===========================================================================
This file contains the main features as well as overviews of specific
bug fixes (and other actions) for each version of hwloc since version
0.9 (as initially released as "libtopology", then re-branded to "hwloc"
in v0.9.1).
Version 1.2.1
-------------
* Improve support of AMD Bulldozer "Compute-Unit" modules by detecting
logical processors with different core IDs on Linux.
* Fix hwloc-ps crash when listing processes from another Linux cpuset.
Thanks to Carl Smith for reporting the problem.
* Fix build on AIX and Solaris. Thanks to Carl Smith and Andreas Kupries
for reporting the problems.
* Fix cache size detection on Darwin. Thanks to Erkcan Özcan for reporting
the problem.
* Make configure fail if --enable-xml or --enable-cairo is given and
proper support cannot be found. Thanks to Andreas Kupries for reporting
the XML problem.
* Fix spurious L1 cache detection on AIX. Thanks to Hendryk Bockelmann
for reporting the problem.
* Fix hwloc_get_last_cpu_location(THREAD) on Linux. Thanks to Gabriele
Fatigati for reporting the problem.
* Fix object distance detection on Solaris.
* Add pthread_self weak symbol to ease static linking.
* Minor documentation fixes.
Version 1.2.0
-------------
* Major features
+ Expose latency matrices in the API as an array of distance structures
within objects. Add several helpers to find distances.
+ Add hwloc_topology_set_distance_matrix() and environment variables
to provide a matrix of distances between a given set of objects.
+ Add hwloc_get_last_cpu_location() and hwloc_get_proc_last_cpu_location()
to retrieve the processors where a process or thread recently ran.
- Add the corresponding --get-last-cpu-location option to hwloc-bind.
+ Add hwloc_topology_restrict() to restrict an existing topology to a
given cpuset.
- Add the corresponding --restrict option to lstopo.
* Minor API updates
+ Add hwloc_bitmap_list_sscanf/snprintf/asprintf to convert between bitmaps
and strings such as 4-5,7-9,12,15-
+ hwloc_bitmap_set/clr_range() now support infinite ranges.
+ Clarify the difference between inserting Misc objects by cpuset or by
parent.
+ hwloc_insert_misc_object_by_cpuset() now returns NULL in case of error.
* Discovery improvements
+ x86 backend (for freebsd): add x2APIC support
+ Support standard device-tree phandle, to get better support on e.g. ARM
systems providing it.
+ Detect cache size on AIX. Thanks Christopher and IBM.
+ Improve grouping to support asymmetric topologies.
* Tools
+ Command-line tools now support "all" and "root" special locations
consisting in the entire topology, as well as type names with depth
attributes such as L2 or Group4.
+ hwloc-calc improvements:
- Add --number-of/-N option to report the number of objects of a given
type or depth.
- -I is now equivalent to --intersect for listing the indexes of
objects of a given type or depth that intersects the input.
- Add -H to report the output as a hierarchical combination of types
and depths.
+ Add --thissystem to lstopo.
+ Add lstopo-win, a console-less lstopo variant on Windows.
* Miscellaneous
+ Remove C99 usage from code base.
+ Rename hwloc-gather-topology.sh into hwloc-gather-topology
+ Fix AMD cache discovery on freebsd when there is no L3 cache, thanks
Andriy Gapon for the fix.
Version 1.1.2
-------------
* Fix a segfault in the distance-based grouping code when some objects
are not placed in any group. Thanks to Bernd Kallies for reporting
the problem and providing a patch.
* Fix the command-line parsing of hwloc-bind --mempolicy interleave.
Thanks to Guy Streeter for reporting the problem.
* Stop truncating the output in hwloc_obj_attr_snprintf() and in the
corresponding lstopo output. Thanks to Guy Streeter for reporting the
problem.
* Fix object levels ordering in synthetic topologies.
* Fix potential incoherency between device tree and kernel information,
when SMT is disabled on Power machines.
* Fix and document the behavior of hwloc_topology_set_synthetic() in case
of invalid argument. Thanks to Guy Streeter for reporting the problem.
* Add some verbose error message reporting when it looks like the OS
gives erroneous information.
* Do not include unistd.h and stdint.h in public headers on Windows.
* Move config.h files into their own subdirectories to avoid name
conflicts when AC_CONFIG_HEADERS adds -I's for them.
* Remove the use of declaring variables inside "for" loops.
* Some other minor fixes.
* Many minor documentation fixes.
Version 1.1.1
-------------
* Add hwloc_get_api_version() which returns the version of hwloc used
at runtime. Thanks to Guy Streeter for the suggestion.
* Fix the number of hugepages reported for NUMA nodes on Linux.
* Fix hwloc_bitmap_to_ulong() right after allocating the bitmap.
Thanks to Bernd Kallies for reporting the problem.
* Fix hwloc_bitmap_from_ith_ulong() to properly zero the first ulong.
Thanks to Guy Streeter for reporting the problem.
* Fix hwloc_get_membind_nodeset() on Linux.
Thanks to Bernd Kallies for reporting the problem and providing a patch.
* Fix some file descriptor leaks in the Linux discovery.
* Fix the minimum width of NUMA nodes, caches and the legend in the graphical
lstopo output. Thanks to Jirka Hladky for reporting the problem.
* Various fixes to bitmap conversion from/to taskset-strings.
* Fix and document snprintf functions behavior when the buffer size is too
small or zero. Thanks to Guy Streeter for reporting the problem.
* Fix configure to avoid spurious enabling of the cpuid backend.
Thanks to Tim Anderson for reporting the problem.
* Cleanup error management in hwloc-gather-topology.sh.
Thanks to Jirka Hladky for reporting the problem and providing a patch.
* Add a manpage and usage for hwloc-gather-topology.sh on Linux.
Thanks to Jirka Hladky for providing a patch.
* Memory binding documentation enhancements.
Version 1.1.0
-------------
* API
+ Increase HWLOC_API_VERSION to 0x00010100 so that API changes may be
detected at build-time.
+ Add a memory binding interface.
+ The cpuset API (hwloc/cpuset.h) is now deprecated. It is replaced by
the bitmap API (hwloc/bitmap.h) which offers the same features with more
generic names since it applies to CPU sets, node sets and more.
Backward compatibility with the cpuset API and ABI is still provided but
it will be removed in a future release.
Old types (hwloc_cpuset_t, ...) are still available as a way to clarify
what kind of hwloc_bitmap_t each API function manipulates.
Upgrading to the new API only requires to replace hwloc_cpuset_ function
calls with the corresponding hwloc_bitmap_ calls, with the following
renaming exceptions:
- hwloc_cpuset_cpu -> hwloc_bitmap_only
- hwloc_cpuset_all_but_cpu -> hwloc_bitmap_allbut
- hwloc_cpuset_from_string -> hwloc_bitmap_sscanf
+ Add an `infos' array in each object to store couples of info names and
values. It enables generic storage of things like the old dmi board infos
that were previously stored in machine specific attributes.
+ Add linesize cache attribute.
* Features
+ Bitmaps (and thus CPU sets and node sets) are dynamically (re-)allocated,
the maximal number of CPUs (HWLOC_NBMAXCPUS) has been removed.
+ Improve the distance-based grouping code to better support irregular
distance matrices.
+ Add support for device-tree to get cache information (useful on Power
architectures).
* Helpers
+ Add NVIDIA CUDA helpers in cuda.h and cudart.h to ease interoperability
with CUDA Runtime and Driver APIs.
+ Add Myrinet Express helper in myriexpress.h to ease interoperability.
* Tools
+ lstopo now displays physical/OS indexes by default in graphical mode
(use -l to switch back to logical indexes). The textual output still uses
logical by default (use -p to switch to physical indexes).
+ lstopo prefixes logical indexes with `L#' and physical indexes with `P#'.
Physical indexes are also printed as `P#N' instead of `phys=N' within
object attributes (in parentheses).
+ Add a legend at the bottom of the lstopo graphical output, use --no-legend
to remove it.
+ Add hwloc-ps to list process' bindings.
+ Add --membind and --mempolicy options to hwloc-bind.
+ Improve tools command-line options by adding a generic --input option
(and more) which replaces the old --xml, --synthetic and --fsys-root.
+ Cleanup lstopo output configuration by adding --output-format.
+ Add --intersect in hwloc-calc, and replace --objects with --largest.
+ Add the ability to work on standard input in hwloc-calc.
+ Add --from, --to and --at in hwloc-distrib.
+ Add taskset-specific functions and command-line tools options to
manipulate CPU set strings in the format of the taskset program.

Introduction
hwloc provides command line tools and a C API to obtain the hierarchical map of
key computing elements, such as: NUMA memory nodes, shared caches, processor
sockets, processor cores, and processing units (logical processors or
"threads"). hwloc also gathers various attributes such as cache and memory
information, and is portable across a variety of different operating systems
and platforms.
hwloc primarily aims at helping high-performance computing (HPC) applications,
but is also applicable to any project seeking to exploit code and/or data
locality on modern computing platforms.
Note that the hwloc project represents the merger of the libtopology project
from INRIA and the Portable Linux Processor Affinity (PLPA) sub-project from
Open MPI. Both of these prior projects are now deprecated. The first hwloc
release was essentially a "re-branding" of the libtopology code base, but with
both a few genuinely new features and a few PLPA-like features added in. Prior
releases of hwloc included documentation about switching from PLPA to hwloc;
this documentation has been dropped on the assumption that everyone who was
using PLPA has already switched to hwloc.
hwloc supports the following operating systems:
* Linux (including old kernels not having sysfs topology information, with
knowledge of cpusets, offline CPUs, ScaleMP vSMP, and Kerrighed support)
* Solaris
* AIX
* Darwin / OS X
* FreeBSD and its variants, such as kFreeBSD/GNU
* OSF/1 (a.k.a., Tru64)
* HP-UX
* Microsoft Windows
hwloc only reports the number of processors on unsupported operating systems;
no topology information is available.
For development and debugging purposes, hwloc also offers the ability to work
on "fake" topologies:
* Symmetrical tree of resources generated from a list of level arities
* Remote machine simulation through the gathering of Linux sysfs topology
files
hwloc can display the topology in a human-readable format, either in graphical
mode (X11), or by exporting in one of several different formats, including:
plain text, PDF, PNG, and FIG (see CLI Examples below). Note that some of the
export formats require additional support libraries.
hwloc offers a programming interface for manipulating topologies and objects.
It also brings a powerful CPU bitmap API that is used to describe topology
objects location on physical/logical processors. See the Programming Interface
below. It may also be used to binding applications onto certain cores or memory
nodes. Several utility programs are also provided to ease command-line
manipulation of topology objects, binding of processes, and so on.
Installation
hwloc (http://www.open-mpi.org/projects/hwloc/) is available under the BSD
license. It is hosted as a sub-project of the overall Open MPI project (http://
www.open-mpi.org/). Note that hwloc does not require any functionality from
Open MPI -- it is a wholly separate (and much smaller!) project and code base.
It just happens to be hosted as part of the overall Open MPI project.
Nightly development snapshots are available on the web site. Additionally, the
code can be directly checked out of Subversion:
shell$ svn checkout http://svn.open-mpi.org/svn/hwloc/trunk hwloc-trunk
shell$ cd hwloc-trunk
shell$ ./autogen.sh
Note that GNU Autoconf >=2.63, Automake >=1.10 and Libtool >=2.2.6 are required
when building from a Subversion checkout.
Installation by itself is the fairly common GNU-based process:
shell$ ./configure --prefix=...
shell$ make
shell$ make install
The hwloc command-line tool "lstopo" produces human-readable topology maps, as
mentioned above. It can also export maps to the "fig" file format. Support for
PDF, Postscript, and PNG exporting is provided if the "Cairo" development
package can be found when hwloc is configured and build. Similarly, lstopo's
XML support requires the libxml2 development package.
CLI Examples
On a 4-socket 2-core machine with hyperthreading, the lstopo tool may show the
following graphical output:

Programming Interface
The basic interface is available in hwloc.h. It essentially offers low-level
routines for advanced programmers that want to manually manipulate objects and
follow links between them. Documentation for everything in hwloc.h are provided
later in this document. Developers should also look at hwloc/helper.h (and also
in this document, which provides good higher-level topology traversal examples.
To precisely define the vocabulary used by hwloc, a Terms and Definitions
section is available and should probably be read first.
Each hwloc object contains a cpuset describing the list of processing units
that it contains. These bitmaps may be used for CPU binding and Memory binding.
hwloc offers an extensive bitmap manipulation interface in hwloc/bitmap.h.
Moreover, hwloc also comes with additional helpers for interoperability with
several commonly used environments. See the Interoperability With Other
Software section for details.
The complete API documentation is available in a full set of HTML pages, man
pages, and self-contained PDF files (formatted for both both US letter and A4
formats) in the source tarball in doc/doxygen-doc/.
NOTE: If you are building the documentation from a Subversion checkout, you
will need to have Doxygen and pdflatex installed -- the documentation will be
built during the normal "make" process. The documentation is installed during
"make install" to $prefix/share/doc/hwloc/ and your systems default man page
tree (under $prefix, of course).
Portability
As shown in CLI Examples, hwloc can obtain information on a wide variety of
hardware topologies. However, some platforms and/or operating system versions
will only report a subset of this information. For example, on an PPC64-based
system with 32 cores (each with 2 hardware threads) running a default
2.6.18-based kernel from RHEL 5.4, hwloc is only able to glean information
about NUMA nodes and processor units (PUs). No information about caches,
sockets, or cores is available.
Similarly, Operating System have varying support for CPU and memory binding,
e.g. while some Operating Systems provide interfaces for all kinds of CPU and
memory bindings, some others provide only interfaces for a limited number of
kinds of CPU and memory binding, and some do not provide any binding interface
at all. Hwloc's binding functions would then simply return the ENOSYS error
(Function not implemented), meaning that the underlying Operating System does
not provide any interface for them. CPU binding and Memory binding provide more
information on which hwloc binding functions should be preferred because
interfaces for them are usually available on the supported Operating Systems.
Here's the graphical output from lstopo on this platform when Simultaneous
Multi-Threading (SMT) is enabled:
ppc64-with-smt.png
And here's the graphical output from lstopo on this platform when SMT is
disabled:
ppc64-without-smt.png
Notice that hwloc only sees half the PUs when SMT is disabled. PU #15, for
example, seems to change location from NUMA node #0 to #1. In reality, no PUs
"moved" -- they were simply re-numbered when hwloc only saw half as many.
Hence, PU #15 in the SMT-disabled picture probably corresponds to PU #30 in the
SMT-enabled picture.
This same "PUs have disappeared" effect can be seen on other platforms -- even
platforms / OSs that provide much more information than the above PPC64 system.
This is an unfortunate side-effect of how operating systems report information
to hwloc.
Note that upgrading the Linux kernel on the same PPC64 system mentioned above
to 2.6.34, hwloc is able to discover all the topology information. The
following picture shows the entire topology layout when SMT is enabled:
ppc64-full-with-smt.png
Developers using the hwloc API or XML output for portable applications should
therefore be extremely careful to not make any assumptions about the structure
of data that is returned. For example, per the above reported PPC topology, it
is not safe to assume that PUs will always be descendants of cores.
Additionally, future hardware may insert new topology elements that are not
available in this version of hwloc. Long-lived applications that are meant to
span multiple different hardware platforms should also be careful about making
structure assumptions. For example, there may someday be an element "lower"
than a PU, or perhaps a new element may exist between a core and a PU.
API Example
The following small C example (named ``hwloc-hello.c'') prints the topology of
the machine and bring the process to the first logical processor of the second
core of the machine.

hwloc provides a pkg-config executable to obtain relevant compiler and linker
flags. For example, it can be used thusly to compile applications that utilize
the hwloc library (assuming GNU Make):
CFLAGS += $(pkg-config --cflags hwloc)
LDLIBS += $(pkg-config --libs hwloc)
cc hwloc-hello.c $(CFLAGS) -o hwloc-hello $(LDLIBS)
On a machine with 4GB of RAM and 2 processor sockets -- each socket of which
has two processing cores -- the output from running hwloc-hello could be
something like the following:
shell$ ./hwloc-hello
*** Objects at level 0
Index 0: Machine(3938MB)
*** Objects at level 1
Index 0: Socket#0
Index 1: Socket#1
*** Objects at level 2

Index 2: Core#3

Questions and Bugs
Questions should be sent to the devel mailing list (http://www.open-mpi.org/
community/lists/hwloc.php). Bug reports should be reported in the tracker (
https://svn.open-mpi.org/trac/hwloc/).
If hwloc discovers an incorrect topology for your machine, the very first thing
you should check is to ensure that you have the most recent updates installed
for your operating system. Indeed, most of hwloc topology discovery relies on
hardware information retrieved through the operation system (e.g., via the /sys
virtual filesystem of the Linux kernel). If upgrading your OS or Linux kernel
does not solve your problem, you may also want to ensure that you are running
the most recent version of the BIOS for your machine.
If those things fail, contact us on the mailing list for additional help.
Please attach the output of lstopo after having given the --enable-debug option
to ./configure and rebuilt completely, to get debugging output.
History / Credits
hwloc is the evolution and merger of the libtopology (http://
runtime.bordeaux.inria.fr/libtopology/) project and the Portable Linux
Processor Affinity (PLPA) (http://www.open-mpi.org/projects/plpa/) project.
Because of functional and ideological overlap, these two code bases and ideas
were merged and released under the name "hwloc" as an Open MPI sub-project.
libtopology was initially developed by the INRIA Runtime Team-Project (http://
runtime.bordeaux.inria.fr/) (headed by Raymond Namyst (http://
dept-info.labri.fr/~namyst/). PLPA was initially developed by the Open MPI
development team as a sub-project. Both are now deprecated in favor of hwloc,
which is distributed as an Open MPI sub-project.

# serial 5 lt~obsolete.m4
# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

===========================================================================
This file contains the main features as well as overviews of specific
bug fixes (and other actions) for each version of PLPA since
version 1.0.
1.3.2
-----
- Removed a clause from AMD's license notice in plpa_map.c by
direction from Barry S. Newberger, Ph.D., Assistant General Counsel,
Advanced Micro Devices, Inc. per a Red Hat licensing concern
(initiated at https://bugzilla.redhat.com/show_bug.cgi?id=530230).
Removing this clause alleviates Red Hat's concern, even though this
resolution not shown on the above-cited bugzilla ticket.
- Julian Seward noticed that PLPA's use of the Valgrind API in the
affinity API probe was incorrect and suggested an improvement. Even
though we're ramping down PLPA development, I couldn't really ignore
the Valgrind author's suggestion!
1.3.1
-----
- Fixed bug identified by Eugene Loh at Sun; plpa-taskset -c ranges
were accidentally excluding the processor ID at the top of the
range.
- For standalone PLPA builds, the .so library is now versioned
according to the GNU Libtool guidelines.
1.3
---
- Added --with-valgrind support that allows building support for
Valgrind into PLPA (i.e., tell Valgrind to not warn about things
that we know are ok).
1.2
---
- Allow mapping from simple/contiguous processor, socket, and core
numbers to the corresponding back-end Linux ID (and clean up
documentation references between "X number" and "X ID", where X is
one of processor, socket, core).
- Support CPU hot plugging.
- Add explicit control over the PLPA topology information cache.
1.1.1
-----
- Ensure that --enable-included also disables executables by default.
Thanks to Brian Curtis for identifying the problem and supplying a
patch.
- Add ENABLE_EXECUTABLES m4 macro to allow behavior in m4
configuration analogous to "--enable-included --enable-executables".
1.1
---
- New command: plpa-taskset. It is intended as a drop-in replacement
for the "taskset" command, except it also understands sockets and
cores. See "plpa-taskset --help" for more details
- Renamed "plpa_info" to "plpa-info".
- Added PLPA_{MAJOR|MINOR|RELEASE}_VERSION integer macros in plpa.h.
This release, they have the values of 1, 1, and 0, respectively.
- Add new API functions to map from (socket,core) back and forth from
the Linux virtual processor ID. Thanks to AMD for the initial code
contribution that made this possible. See the documentation for
plpa_map_to_processor_id() as a starting point for more
information.
- Various fixes to "included" mode.
1.0.5
-----
- Fix an issue where the PLPA get/set affinity functions would only
operate on the current process; the PID argument to these functions
was effectively ignored.
1.0.4
-----
- Fix some 64 bit issues. Thanks to David Creasy for reporting the
problems.
- Fix plpa.h to be C++-friendly. Thanks to Emmanuel Paris for
pointing out this problem.
1.0.3
-----
- Resolve some sizing / units ambiguities that mistakenly did not make
it into 1.0.1. Thanks to Bert Wesarg for pointing these problems out.
1.0.2
-----
- Ensure that plpa_sched_[set|get]affinity() returns 0 upon success.
Thanks to David Creasy for bringing this to our attention.
1.0.1
-----
- Specify that cpusetsize should be in units of bytes and add some
missing "* 8"'s in plpa_dispatch.c.
1.0
---
- Initial release.
0.9a2
-----
- Change the back-end type of the plpa_bitmask_t to unsigned long
instead of unsigned char to avoid an endian problem.
- No longer attempt to set the affinity in plpa_api_probe() to avoid a
possible race condition (setting it after getting it).
- Fix PLPA_CPU_ZERO macro. Thanks to Bogdan Costescu for pointing
this out.
0.9a1
-----
Initial public release.

===========================================================================
This is the Portable Linux Processor Affinity (PLPA) package
(pronounced "pli-pa"). The PLPA has evolved over time to provide the
following capabilities:
1. Provide a stable API on Linux for processor affinity (Linux has
provided three different API signatures over time).
2. Provide a simple API that translates between Linux processor ID and
(socket ID, core ID) tuples, and allows querying processor topology
information on supported platforms.
3. Provide a command-line executable (plpa-taskset(1)) that provides
all the same functionality as the venerable taskset(1) command, and
several extensions, including the ability to bind processes to
specific (socket, core) tuples on supported platforms.
Note that the PLPA is fully embeddable, meaning that it can be wholly
contained in larger software packages that wish to have a single,
stable version of processor affinity API functionality. See below for
more details on embedding.
Also note that PLPA's socket/core and other topology information is
only available on certain platforms. Specifically, PLPA reads the
/sys filesystem to glean its information; if your system does not
export processor topology information through /sys, the PLPA cannot
provide that information. For example, AMD/Intel processor topology
support was included in Linux kernel v2.6.16, but POWER processor
topology information is not yet supported as of Linux kernel v2.6.26.
In a world where the processor counts in hosts are [again] increasing,
particularly where at least some of them are NUMA-based architectures,
processor affinity is becoming more important. We hope that the PLPA
is helpful to you. Enjoy.
Note that if you're looking into processor affinity, and if you're on
a NUMA machine, you probably also want to look into libnuma:
ftp://ftp.suse.com/pub/people/ak/numa/
If you are a developer, keep reading. If you are a system
administrator or other end-user, you're probably more interested in
using the plpa-info(1) and plpa-taskset(1) executable commands; see
the output of "plpa-info" and "plpa-taskset --help" for more
information.
===========================================================================
The following text is specific technical information about the
original problem that PLPA Was created to solve.
The original intent for the PLPA was for developers who wished to use
Linux processor affinity via the sched_setaffinity() and
sched_getaffinity() library calls, but don't want to wade through the
morass of 3 different APIs that have been offered through the life of
these calls in various Linux distributions and glibc versions.
Specifically, to compile for any given Linux system, you need some
complex compile-time tests to figure out which of the 3 APIs to use.
And if you want your application to be binary portable across
different Linux distributions, more complex run-time tests (and horrid
compile-time trickery) are required to figure out which API the system
you are running on uses.
These problems all stem from the fact that the same 2 symbols have had
three different APIs (with different numbers and types of
parameters) throughout their life in Linux. Ick.
The PLPA is an attempt to solve this problem by providing a single API
that developers can write to. It provides three things:
1. A single API that developers can write to, regardless of what
back-end API the system you are compiling on has.
2. A run-time test and dispatch that will invoke the Right back-end
API depending on what back-end API the system you are running on
has.
3. Mapping information between (socket ID, core ID) tuples and Linux
virtual processor IDs.
===========================================================================
What, exactly, is the problem? History.
----------------------------------------
There are at least 3 different ways that sched_setaffinity is
implemented in glibc (only one of which is documented in the
sched_setaffinity(2) man page), and some corresponding changes
to what the kernel considers to be valid arguments:
1. int sched_setaffinity(pid_t pid, unsigned int len, unsigned
long *mask);
This originated in the time period of 2.5 kernels and some distros
back-ported it to their 2.4 kernels and libraries. It's unknown if
this version was ever packaged with any 2.6 kernels.
2. int sched_setaffinity (pid_t __pid, size_t __cpusetsize,
const cpu_set_t *__cpuset);
This appears to be in recent distros using 2.6 kernels. We don't
know exactly when #1 changed into #2. However, this prototype is nice
because the cpu_set_t type is accompanied by fdset-like CPU_ZERO(),
CPU_SET(), CPU_ISSET(), etc. macros.
3. int sched_setaffinity (pid_t __pid, const cpu_set_t *__mask);
(note the missing len parameter) This is in at least some Linux
distros (e.g., MDK 10.0 with a 2.6.3 kernel, and SGI Altix, even
though the Altix uses a 2.4-based kernel and therefore likely
back-ported the 2.5 work or originated it in the first place).
Similar to #2, the cpu_set_t type is accompanied by fdset-like
CPU_ZERO(), CPU_SET(), CPU_ISSET(), etc. macros.
But wait, it gets worse.
Remember that getting/setting processor affinity has to involve the
kernel. The sched_[sg]etaffinity() glibc functions typically do a
little error checking and then make a syscall down into the kernel to
actually do the work. There are multiple possibilities for problems
here as the amount of checking has changed:
1. The glibc may support the affinity functions, but the kernel may
not (and vice versa).
This is typically only an issue with slightly older Linux distributions.
Mandrake 9.2 is an example of this. PLPA can detect this at run-time
and turn its internal functions into no-ops and return appropriate error
codes (ENOSYS).
2. The glibc affinity functions may be buggy (i.e., they pass bad data
down to the syscall).
This is fortunately restricted to some older versions of glibc, and
is relatively easy to check for at run-time. PLPA reliably detects
this situation at run-time and returns appropriate error codes
(ENOSYS).
The original SuSE 9.1 version seems to have this problem, but it was
fixed it somewhere in the SuSE patching history (it is unknown exactly
when). Specifically, updating to the latest SuSE 9.1 patch level
(as of Dec 2005) seems to fix the problem.
3. The CPU_* macros for manipulating cpu_set_t bitmasks may not
compile because of typo bugs in system header files.
PLPA avoids this problem by providing its own PLPA_CPU_* macros for
manipulating CPU bitmasks. See "How do I use PLPA?", below, for
more details.
The PLPA avoids all the glibc issues by using syscall() to directly
access the kernel set and get affinity functions. This is described
below.
===========================================================================
How does PLPA work?
-------------------
Jeff Squyres initially sent a mail to the Open MPI developer's mailing
list explaining the Linux processor affinity problems and asking for
help coming up with a solution (particularly for binary
compatibility):
http://www.open-mpi.org/community/lists/devel/2005/11/0558.php
Discussion on that thread and others eventually resulted in the
run-time tests that form the heart of the PLPA. Many thanks to Paul
Hargrove and Bogdan Costescu for their time and effort to get these
tests right.
PLPA was written so that other developers who want to use processor
affinity in Linux don't have to go through this mess. The PLPA
provides a single interface that can be used on any platform,
regardless of which back-end API variant it has. This includes both
the sched_setaffinity() and sched_getaffinity() calls as well as the
CPU_*() macros.
The PLPA avoids glibc altogether -- although tests were developed that
could *usually* figure out which glibc variant to use at run time,
there were still some cases where it was either impossible to
determine or the glibc interface itself was buggy. Hence, it was
decided that a simpler approach was simply to use syscall() to invoke
the back-end kernel functions directly.
The kernel functions have gone through a few changes as well, so the
PLPA does a few run-time tests to determine which variant to use
before actually invoking the back-end functions with the
user-specified arguments.
NOTE: The run-time tests that the PLPA performs involve getting the
current affinity for the process in question and then attempting to
set them back to the same value. By definition, this introduces a
race condition (there is no atomic get-and-set functionality for
processor affinity). The PLPA cannot guarantee consistent results if
multiple entities (such as multiple threads or multiple processes) are
setting the affinity for a process at the same time. In a worst case
scenario, the PLPA may actually determine that it cannot determine the
kernel variant at run time if another entity modifies a process'
affinity while PLPA is executing its run-time tests.
===========================================================================
Does PLPA make truly portable binaries?
---------------------------------------
As much as Linux binaries are portable, yes. That is, if you have
within your power to make a binary that is runnable on several
different Linux distributions/versions/etc., then you may run into
problems with the Linux processor affinity functions. PLPA attempts
to solve this problem for you by *also* making the Linux processor
affinity calls be binary portable.
Hence, you need to start with something that is already binary
portable (perhaps linking everything statically) -- then PLPA will be
of help to you. Do not fall into the misconception that PLPA will
magically make your executable be binary portable between different
Linux variants.
===========================================================================
How do I use PLPA?
------------------
There are three main uses of the PLPA:
1. Using the plpa-info(1) executable to check if your system supports
processor affinity and the PLPA can determine which to use at
run-time.
2. Developers using the PLPA library both to enable source and binary
Linux processor affinity portability, and to write
processor-topology-aware applications.
3. Using the plpa-taskset(1) executable to bind arbitrary executables
to Linux virtual processor IDs and/or specific socket/core tuples.
In more detail:
1. The plpa-info(1) executable is a few simple calls into the PLPA
library that checks which API variant the system it is running on
has. If the kernel supports processor affinity and the PLPA is
able to figure out which API variant to use, it prints "Kernel
affinity support: no". Other responses indicate an error. The
"--topo" switch will print out basic topology information about
your system, if supported.
Since the PLPA library abstracts this kind of problem away, this is
more a diagnostic tool than anything else.
See "plpa-info --help" for more information. A man page does not
yet exist, unfortunately.
Note that plpa-info is *only* compiled and installed if PLPA is
installed as a standalone package (see below).
2. Developers can use this package by including the <plpa.h> header
file and using the following prototypes for setting and getting
processor affinity:
int plpa_sched_setaffinity(pid_t pid, size_t cpusetsize,
const plpa_cpu_set_t *cpuset);
int plpa_sched_getaffinity(pid_t pid, size_t cpusetsize,
const plpa_cpu_set_t *cpuset)
These functions perform run-time tests to determine which back-end
API variant exists on the system and then dispatch to it correctly.
The units of cpusetsize is number of bytes. This should normally
just be sizeof(*cpuset), but is made available as a parameter to
allow for future expansion of the PLPA (stay tuned).
The observant reader will notice that this is remarkably similar to
the one of the Linux API's (the function names are different and
the CPU set type is different). PLPA also provides several macros
for manipulating the plpa_cpu_set_t bitmask, quite similar to FDSET
macros (see "What, Exactly, Is the Problem?" above for a
description of problems with the native CPU_* macros):
- PLPA_CPU_ZERO(&cpuset): Sets all bits in a plpa_cpu_set_t to
zero.
- PLPA_CPU_SET(num, &cpuset): Sets bit <num> of <cpuset> to one.
- PLPA_CPU_CLR(num, &cpuset): Sets bit <num> of <cpuset> to zero.
- PLPA_CPU_ISSET(num, &cpuset): Returns one if bit <num> of
<cpuset> is one; returns zero otherwise.
Note that all four macros take a *pointer* to a plpa_cpu_set_t, as
denoted by "&cpuset" in the descriptions above.
Also note that he PLPA distinguishes between Linux processor,
socket, and core IDs and processor, socket, and core numbers. The
*Linux IDs* are kernel-assigned integer values that do not
necessarily start with zero and are not necessarily contiguous.
The *numbers* start with 0 and are contiguous to (N-1). The
numbers are therefore mainly a human convenience; they may or may
not exactly correspond to the Linux IDs; it is safest to assume
that they do not.
The following API functions are also available on supported
platforms with kernels that support topology information (e.g.,
AMD/Intel platforms with Linux kernel v2.6.16 or later). The list
below is a summary only; see plpa.h for a specific list of function
signatures:
- plpa_have_topology_information()
Will return 1 if the PLPA is able to provide topology
information, 0 otherwise. If 0 is returned, all the functions
below will return a negative value to signify a graceful failure.
- plpa_map_to_processor_id()
Take a (socket ID, core ID) tuple and map it to a Linux processor
ID
- plpa_map_to_socket_core()
Take a Linux processor ID and map it to a (socket ID, core ID)
tuple
- plpa_get_processor_info()
Return the number of processors and the max Linux processor ID
- plpa_get_processor_id()
Return the Linux processor ID for the Nth processor (starting
with 0)
- plpa_get_processor_flags()
Return whether a Linux processor ID exists, and if so, if it is
online
- plpa_get_socket_info()
Return the number of sockets and the max Linux socket ID
- plpa_get_socket_id()
Return the Linux socket ID for the Nth socket (starting with 0)
- plpa_get_core_info()
For a given socket ID, return the number of cores and the max
Linux core ID
- plpa_get_core_id()
For a given socket ID, return the Linux core ID of the Nth core
(starting with 0)
- plpa_get_core_flags()
Return whether a (socket ID,core ID) tuple exists, and if so, if
it is online
- plpa_set_cache_behavior()
Tell PLPA to use (or not) a local cache for the topology
information, or to refresh the cache right now
- plpa_finalize()
Release all internal resources allocated and maintained by the
PLPA. It is permissible to invoke other PLPA functions after
plpa_finalize(), but if you want to release PLPA's resources, you
will need to invoke plpa_finalize() again. Note that it is not
necessary (but harmless) to invoke plpa_finalize() on systems
where plpa_have_topology_information() returns that the topology
information is not supported.
*** NOTE: Topology information (i.e., (socket ID, core ID) tuples)
may not be reported for offline processors. Hence, if any
processors are offline, the socket/core values returned by PLPA
will likely change once the processor is brought back online.
Sorry; this is how the Linux kernel works -- there's nothing
PLPA can do about it.
The above functions are slightly more documented in plpa.h.
Contributions of real man pages would be greatly appreciated.
3. The plpa-taskset(1) executable represents an evolution of the
venerable "taskset(1)" command. It allows binding of arbitrary
processes to specific Linux processor IDs and/or specific (socket
ID, core ID) tuples. It supports all the same command line syntax
of the taskset(1) command, but also supports additional syntax for
specifying socket and core IDs. Hence, you can launch
processor-bound jobs without needing to modify their source code to
call the PLPA library. See "plpa-taskset --help" for more
information on the command line options available, and brief
examples of usage. A man page does not yet exist, unfortunately.
===========================================================================
How do I compile / install the PLPA as a standalone package?
------------------------------------------------------------
The PLPA uses the standard GNU Autoconf/Automake/Libtool toolset to
build and install itself. This means that generally, the following
works:
shell$ ./configure --prefix=/where/you/want/to/install
[...lots of output...]
shell$ make all
[...lots of output...]
shell$ make install
Depending on your --prefix, you may need to run the "make install"
step as root or some other privileged user.
There are a few noteworthy configure options listed below. The
enable/disable options are shown in their non-default form. For
example, if --enable-foo is shown below, it is because --disable-foo
is the default.
--enable-emulate: allow using PLPA on platforms that do not have
__NR_sched_setaffinity (e.g., OS X); usually only useful in
development / testing scenarios.
--disable-executables: do not build the PLPA executables; only build
the library.
--enable-included-mode: build PLPA in the "included" mode (see
below).
--enable-debug: this option is probably only helpful for PLPA
developers.
--with-plpa-symbol-prefix=STRING: a string prefix to add to all public
PLPA symbols. This is usually only useful in included mode (see
below).
--with-valgrind(=DIR): require building PLPA with Valgrind support
(requires finding include/valgrind/memcheck.h). This will add a
small number of Valgrind annotations in the PLPA code base that
remove false/irrelevant Valgrind warnings. The =DIR clause is only
necessary if Valgrind's header files cannot be found by the
preprocessor's default search path.
"make install" will install the following:
- <plpa.h> in $includedir (typically $prefix/include)
- libplpa.la and libplpa.a and/or libplpa.so in $libdir (typically
$prefix/lib)
- plpa-info(1) executable in $bindir (typically $prefix/bin)
- plpa-taskset(1) executable in $bindir (typically $prefix/bin)
Note that since PLPA builds itself with GNU Libtool, it can be built
as a static or shared library (or both). The default is to build a
shared library. You can enable building a static library by supplying
the "--enable-static" argument to configure; you can disable building
the shared library by supplying the "--disable-shared" argument to
configure. "make install" will install whichever library was built
(or both).
"make uninstall" will fully uninstall PLPA from the prefix directory
(again, depending in filesystem permissions, you may need to run this
as root or some privileged user).
===========================================================================
How do I include/embed PLPA in my software package?
---------------------------------------------------
It can be desirable to include PLPA in a larger software package
(be sure to check out the LICENSE file) so that users don't have to
separately download and install it before installing your software
(after all, PLPA is a tiny little project -- why make users bother
with it?).
When used in "included" mode, PLPA will:
- not install any header files
- not build or install any executables
- not build libplpa.* -- instead, it will build libplpa_included.*
There are two ways to put PLPA into "included" mode. From the
configure command line:
shell$ ./configure --enable-included-mode ...
Or by directly integrating PLPA's m4 configure macro in your configure
script and invoking a specific macro to enable the included mode.
Every project is different, and there are many different ways of
integrating PLPA into yours. What follows is *one* example of how to
do it.
Copy the PLPA directory in your source tree and include the plpa.m4
file in your configure script -- perhaps with the following line in
acinclude.m4 (assuming the use of Automake):
m4_include(path/to/plpa.m4)
The following macros can then be used from your configure script (only
PLPA_INIT *must* be invoked if using the m4 macros):
- PLPA_STANDALONE
Force the building of PLPA in standalone mode. Overrides the
--enable-included-mode command line switch.
- PLPA_INCLUDED
Force the building of PLPA in included mode.
- PLPA_SET_SYMBOL_PREFIX(foo)
Tells the PLPA to prefix all types and public symbols with "foo"
instead of "plpa_". This is recommended behavior if you are
including PLPA in a larger project -- it is possible that your
software will be combined with other software that also includes
PLPA. If you both use different symbol prefixes, there will be no
type/symbol clashes, and everything will compile and link
successfully. If you both include PLPA and do not change the symbol
prefix, it is likely that you will get multiple symbol definitions
when linking if an external PLPA is linked against your library /
application. Note that the PLPA_CPU_*() macros are *NOT* prefixed
(because they are only used when compiling and therefore present no
link/run-time conflicts), but all other types, enum values, and
symbols are. Enum values are prefixed with an upper-case
translation if the prefix supplied. For example,
PLPA_SET_SYMBOL_PREFIX(foo_) will result in foo_init() and
FOO_PROBE_OK. Tip: It might be good to include "plpa" in the
prefix, just for clarity.
- PLPA_DISABLE_EXECUTABLES
Provides the same result as the --disable-executables configure
flag, and is implicit in included mode.
- PLPA_ENABLE_EXECUTABLES
Provides the same result as the --enable-executables configure flag.
If used in conjunction with PLPA_INCLUDED, it must be specified
*after* PLPA_INLCLUDED to have effect, as PLPA_INCLUDED *disables*
executables.
- PLPA_INIT(config-prefix, action-upon-success, action-upon-failure)
Invoke the PLPA tests and setup the PLPA to build. A traversal of
"make" into the PLPA directory should build everything (it is safe
to list the PLPA directory in the SUBDIRS of a higher-level
Makefile.am, for example). ***PLPA_INIT must be invoked after the
STANDALONE, INCLUDED, SET_SYMBOL_PREFIX, DISABLE_EXECUTABLES, and
ENABLE_EXECUTABLES macros.*** The first argument is the prefix to
use for AC_OUTPUT files. Hence, if your embedded PLPA is located in
the source tree at contrib/plpa, you should pass [contrib/plpa] as
the first argument.
- PLPA_DO_AM_CONDITIONALS
If you embed PLPA in a larger project and build it conditionally
(e.g., if PLPA_INIT is in a conditional), you must unconditionally
invoke PLPA_DO_AM_CONDITIONALS to avoid warnings from Automake (for
the cases where PLPA is not selected to be built). This macro is
necessary because PLPA uses some AM_CONDITIONALs to build itself;
AM_CONDITIONALs cannot be defined conditionally. It is safe (but
unnecessary) to call PLPA_DO_AM_CONDITIONALS even if PLPA_INIT is
invoked unconditionally.
Here's an example of integrating with a larger project named sandbox:
----------
shell$ cd sandbox
shell$ cp -r /somewhere/else/plpa-<version> plpa
shell$ edit acinclude.m4
...add the line "m4_include(plpa/config/plpa.m4)"...
shell$ edit Makefile.am
...add "plpa" to SUBDIRS...
...add "$(top_builddir)/plpa/src/libplpa/libplpa_included.la" to
my executable's LDADD line...
...add "-I$(top_builddir)/plpa/src/libplpa" to AM_CPPFLAGS
shell$ edit configure.ac
...add "PLPA_INCLUDED" line...
...add "PLPA_SET_SYMBOL_PREFIX(sandbox_plpa_)" line...
...add "PLPA_INIT([./plpa], [plpa_happy=yes], [plpa_happy=no])" line...
...add error checking for plpa_happy=no case...
shell$ edit src/my_program.c
...add #include <plpa.h>...
...add calls to sandbox_plpa_sched_setaffinity()...
shell$ aclocal
shell$ autoconf
shell$ libtoolize --automake
shell$ automake -a
shell$ ./configure
...lots of output...
shell$ make
...lots of output...
----------
===========================================================================
How can I tell if PLPA is working?
----------------------------------
Run plpa-info; if it says "Kernel affinity support: yes", then PLPA is
working properly.
If you want to compile your own test program to verify it, try
compiling and running the following:
---------------------------------------------------------------------------
#include <stdio.h>
#include <plpa.h>
int main(int argc, char* argv[]) {
plpa_api_type_t p;
if (0 == plpa_api_probe(&p) && PLPA_PROBE_OK == p) {
printf("All is good!\n");
} else {
printf("Looks like PLPA is not working\n");
}
return 0;

---------------------------------------------------------------------------
You may need to supply appropriate -I and -L arguments to the
compiler/linker, respectively, to tell it where to find the PLPA
header and library files. Also don't forget to supply -lplpa to link
in the PLPA library itself. For example, if you configured PLPA with:
shell$ ./configure --prefix=$HOME/my-plpa-install
Then you would compile the above program with:
shell$ gcc my-plpa-test.c \
-I$HOME/my-plpa-install/include \
-L$HOME/my-plpa-install/lib -lplpa \
-o my-plpa-test
shell$ ./my-plpa-test
If it compiles, links, runs, and prints "All is good!", then all
should be well.
===========================================================================
What license does PLPA use?
---------------------------
This package is distributed under the BSD license (see the LICENSE
file in the top-level directory of a PLPA distribution). The
copyrights of several institutions appear throughout the code base
because some of the code was directly derived from the Open MPI
project (http://www.open-mpi.org/), which is also distributed under
the BSD license.
===========================================================================
How do I get involved in PLPA?
------------------------------
The PLPA continues to evolve, particularly as core counts increase and
internal host topology becomes more important. We want to hear your
opinions.
The best way to report bugs, send comments, or ask questions is to
sign up on the user's mailing list:
plpa-users@open-mpi.org
Because of spam, only subscribers are allowed to post to this list
(ensure that you subscribe with and post from exactly the same e-mail

# This is the VERSION file for PLPA, describing the precise version of
# PLPA in this distribution. The various components of the version
# number below are combined to form a single version number string.
# major, minor, and release are generally combined in the form
# <major>.<minor>.<release>. If release is zero, then it is omitted.
major=1
minor=3
release=2
# greek is used for alpha or beta release tags. If it is non-empty,
# it will be appended to the version number. It does not have to be
# numeric. Common examples include a1 (alpha release 1), b1 (beta
# release 1), sc2005 (Super Computing 2005 release). The only
# requirement is that it must be entirely printable ASCII characters
# and have no white space.
greek=
# If want_svn=1, then the SVN r number will be included in the overall
# PLPA version number in some form.
want_svn=0
# If svn_r=-1, then the SVN r numbere will be obtained dynamically at
# run time, either 1) via the "svnversion" command (if this is a
# Subversion checkout) in the form "r<svn_r>", or b) with the date (if
# this is not a Subversion checkout, and the svnversion command cannot
# be used) in the form of "svn<date>". Alternatively, if svn_r is not
# -1, the value of svn_r will be directly appended to the version
# string. This happens during "make dist", for example: if the
# distribution tarball is being made from an SVN checkout, the value
# of svn_r in this file is replaced with the output of "svnversion".
svn_r=r264
# The shared library version of PLPA's public library. This version
# is maintained in accordance with the "Library Interface Versions"
# chapter from the GNU Libtool documentation. PLPA v<=1.3 reported
# version 0:0:0; the next release after v1.3 will explicitly set its
# .so version numbers according to the rules in the Libtool
# documentation. Notes:
# 1. Since version numbers are associated with *releases*, the version
# number maintained on the PLPA SVN trunk (and developer branches) is
# always 0:0:0.
# 2. Version numbers are described in the Libtool current:revision:age
# format.
