===========================================================================
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 1.7.2
-------------
* Do not create invalid block OS devices on very old Linux kernel such
as RHEL4 2.6.9.
* Fix PCI subvendor/device IDs.
* Fix the management of Misc objects inserted by parent.
Thanks to Jirka Hladky for reporting the problem.
* Add a Port<n>State into attribute to OpenFabrics OS devices.
* Add a MICSerialNumber info attribute to Xeon PHI/MIC OS devices.
* Improve verbose error messages when failing to load from XML.
Version 1.7.1
-------------
* Fix a failed assertion in the distance grouping code when loading a XML
file that already contains some groups.
Thanks to Laercio Lima Pilla for reporting the problem.
* Remove unexpected Group objects when loading XML topologies with I/O
objects and NUMA distances.
Thanks to Elena Elkina for reporting the problem and testing patches.
* Fix PCI link speed discovery when using libpciaccess.
* Fix invalid libpciaccess virtual function device/vendor IDs when using
SR-IOV PCI devices on Linux.
* Fix GL component build with old NVCtrl releases.
Thanks to Jirka Hladky for reporting the problem.
* Fix embedding breakage caused by libltdl.
Thanks to Pavan Balaji for reporting the problem.
* Always use the system-wide libltdl instead of shipping one inside hwloc.
* Document issues when enabling plugins while embedding hwloc in another
project, in the documentation section Embedding hwloc in Other Software.
* Add a FAQ entry "How to get useful topology information on NetBSD?"
in the documentation.
* Somes fixes in the renaming code for embedding.
* Miscellaneous minor build fixes.
Version 1.7.0
-------------
* New operating system backends
+ Add BlueGene/Q compute node kernel (CNK) support. See the FAQ in the
documentation for details. Thanks to Jeff Hammond, Christopher Samuel
and Erik Schnetter for their help.
+ Add NetBSD support, thanks to Aleksej Saushev.
* New I/O device discovery
+ Add co-processor OS devices such as "mic0" for Intel Xeon Phi (MIC)
on Linux. Thanks to Jerome Vienne for helping.
+ Add co-processor OS devices such as "cuda0" for NVIDIA CUDA-capable GPUs.
+ Add co-processor OS devices such as "opencl0d0" for OpenCL GPU devices
on the AMD OpenCL implementation.
+ Add GPU OS devices such as ":0.0" for NVIDIA X11 displays.
+ Add GPU OS devices such as "nvml0" for NVIDIA GPUs.
Thanks to Marwan Abdellah and Stefan Eilemann for helping.
These new OS devices have some string info attributes such as CoProcType,
GPUModel, etc. to better identify them.
See the I/O Devices and Attributes documentation sections for details.
* New components
+ Add the "opencl", "cuda", "nvml" and "gl" components for I/O device
discovery.
+ "nvml" also improves the discovery of NVIDIA GPU PCIe link speed.
All of these new components may be built as plugins. They may also be
disabled entirely by passing --disable-opencl/cuda/nvml/gl to configure.
See the I/O Devices, Components and Plugins, and FAQ documentation
sections for details.
* API
+ Add hwloc_topology_get_flags().
+ Add hwloc/plugins.h for building external plugins.
See the Adding new discovery components and plugins section.
* Interoperability
+ Add hwloc/opencl.h, hwloc/nvml.h, hwloc/gl.h and hwloc/intel-mic.h
to retrieve the locality of OS devices that correspond to AMD OpenCL
GPU devices or indexes, to NVML devices or indexes, to NVIDIA X11
displays, or to Intel Xeon Phi (MIC) device indexes.
+ Add new helpers in hwloc/cuda.h and hwloc/cudart.h to convert
between CUDA devices or indexes and hwloc OS devices.
+ Add hwloc_ibv_get_device_osdev() and clarify the requirements
of the OpenFabrics Verbs helpers in hwloc/openfabrics-verbs.h.
* Tools
+ hwloc-info is not only a synonym of lstopo -s anymore, it also
dumps information about objects given on the command-line.
* Documentation
+ Add a section "Existing components and plugins".
+ Add a list of common OS devices in section "Software devices".
+ Add a new FAQ entry "Why is lstopo slow?" about lstopo slowness
issues because of GPUs.
+ Clarify the documentation of inline helpers in hwloc/myriexpress.h
and hwloc/openfabrics-verbs.h.
* Misc
+ Improve cache detection on AIX.
+ The HWLOC_COMPONENTS variable now excludes the components whose
names are prefixed with '-'.
+ lstopo --ignore PU now works when displaying the topology in
graphical and textual mode (not when exporting to XML).
+ Make sure I/O options always appear in lstopo usage, not only when
using pciutils/libpci.
+ Remove some unneeded Linux specific includes from some interoperability
headers.
+ Fix some inconsistencies in hwloc-distrib and hwloc-assembler-remote
manpages. Thanks to Guy Streeter for the report.
+ Fix a memory leak on AIX when getting memory binding.
+ Fix many small memory leaks on Linux.
+ The `libpci' component is now called `pci' but the old name is still
accepted in the HWLOC_COMPONENTS variable for backward compatibility.
Version 1.6.2
-------------
* Use libpciaccess instead of pciutils/libpci by default for I/O discovery.
pciutils/libpci is only used if --enable-libpci is given to configure
because its GPL license may taint hwloc. See the Installation section
in the documentation for details.
* Fix get_cpubind on Solaris when bound to a single PU with
processor_bind(). Thanks to Eugene Loh for reporting the problem
and providing a patch.
Version 1.6.1
-------------
* Fix some crash or buggy detection in the x86 backend when Linux
cgroups/cpusets restrict the available CPUs.
* Fix the pkg-config output with --libs --static.
Thanks to Erik Schnetter for reporting one of the problems.
* Fix the output of hwloc-calc -H --hierarchical when using logical
indexes in the output.
* Calling hwloc_topology_load() multiple times on the same topology
is officially deprecated. hwloc will warn in such cases.
* Add some documentation about existing plugins/components, package
dependencies, and I/O devices specification on the command-line.
Version 1.6.0
-------------
* Major changes
+ Reorganize the backend infrastructure to support dynamic selection
of components and dynamic loading of plugins. For details, see the
new documentation section Components and plugins.
- The HWLOC_COMPONENTS variable lets one replace the default discovery
components.
- Dynamic loading of plugins may be enabled with --enable-plugins
(except on AIX and Windows). It will build libxml2 and libpci
support as separated modules. This helps reducing the dependencies
of the core hwloc library when distributed as a binary package.
* Backends
+ Add CPUModel detection on Darwin and x86/FreeBSD.
Thanks to Robin Scher for providing ways to implement this.
+ The x86 backend now adds CPUModel info attributes to socket objects
created by other backends that do not natively support this attribute.
+ Fix detection on FreeBSD in case of cpuset restriction. Thanks to
Sebastian Kuzminsky for reporting the problem.
* XML
+ Add hwloc_topology_set_userdata_import/export_callback(),
hwloc_export_obj_userdata() and _userdata_base64() to let
applications specify how to save/restore the custom data they placed
in the userdata private pointer field of hwloc objects.
* Tools
+ Add hwloc-annotate program to add string info attributes to XML
topologies.
+ Add --pid-cmd to hwloc-ps to append the output of a command to each
PID line. May be used for showing Open MPI process ranks, see the
hwloc-ps(1) manpage for details.
+ hwloc-bind now exits with an error if binding fails; the executable
is not launched unless binding suceeeded or --force was given.
+ Add --quiet to hwloc-calc and hwloc-bind to hide non-fatal error
messages.
+ Fix command-line pid support in windows tools.
+ All programs accept --verbose as a synonym to -v.
* Misc
+ Fix some DIR descriptor leaks on Linux.
+ Fix I/O device lists when some were filtered out after a XML import.
+ Fix the removal of I/O objects when importing a I/O-enabled XML topology
without any I/O topology flag.
+ When merging objects with HWLOC_IGNORE_TYPE_KEEP_STRUCTURE or
lstopo --merge, compare object types before deciding which one of two
identical object to remove (e.g. keep sockets in favor of caches).
+ Add some GUID- and LID-related info attributes to OpenFabrics
OS devices.
+ Only add CPUType socket attributes on Solaris/Sparc. Other cases
don't report reliable information (Solaris/x86), and a replacement
is available as the Architecture string info in the Machine object.
+ Add missing Backend string info on Solaris in most cases.
+ Document object attributes and string infos in a new Attributes
section in the documentation.
+ Add a section about Synthetic topologies in the documentation.
Version 1.5.2 (some of these changes are in v1.6.2 but not in v1.6)
-------------
* Use libpciaccess instead of pciutils/libpci by default for I/O discovery.
pciutils/libpci is only used if --enable-libpci is given to configure
because its GPL license may taint hwloc. See the Installation section
in the documentation for details.
* Fix get_cpubind on Solaris when bound to a single PU with
processor_bind(). Thanks to Eugene Loh for reporting the problem
and providing a patch.
* Fix some DIR descriptor leaks on Linux.
* Fix I/O device lists when some were filtered out after a XML import.
* Add missing Backend string info on Solaris in most cases.
* Fix the removal of I/O objects when importing a I/O-enabled XML topology
without any I/O topology flag.
* Fix the output of hwloc-calc -H --hierarchical when using logical
indexes in the output.
* Fix the pkg-config output with --libs --static.
Thanks to Erik Schnetter for reporting one of the problems.
Version 1.5.1
-------------
* Fix block OS device detection on Linux kernel 3.3 and later.
Thanks to Guy Streeter for reporting the problem and testing the fix.
* Fix the cpuid code in the x86 backend (for FreeBSD). Thanks to
Sebastian Kuzminsky for reporting problems and testing patches.
* Fix 64bit detection on FreeBSD.
* Fix some corner cases in the management of the thissystem flag with
respect to topology flags and environment variables.
* Fix some corner cases in command-line parsing checks in hwloc-distrib
and hwloc-distances.
* Make sure we do not miss some block OS devices on old Linux kernels
when a single PCI device has multiple IDE hosts/devices behind it.
* Do not disable I/O devices or instruction caches in hwloc-assembler output.
Version 1.5.0
-------------
* Backends
+ Do not limit the number of processors to 1024 on Solaris anymore.
+ Gather total machine memory on FreeBSD.
+ XML topology files do not depend on the locale anymore. Float numbers
such as NUMA distances or PCI link speeds now always use a dot as a
decimal separator.
+ Add instruction caches detection on Linux, AIX, Windows and Darwin.
+ Add get_last_cpu_location() support for the current thread on AIX.
+ Support binding on AIX when threads or processes were bound with
bindprocessor(). Thanks to Hendryk Bockelmann for reporting the issue
and testing patches, and to Farid Parpia for explaining the binding
interfaces.
+ Improve AMD topology detection in the x86 backend (for FreeBSD) using
the topoext feature.
* API
+ Increase HWLOC_API_VERSION to 0x00010500 so that API changes may be
detected at build-time.
+ Add a cache type attribute describind Data, Instruction and Unified
caches. Caches with different types but same depth (for instance L1d
and L1i) are placed on different levels.
+ Add hwloc_get_cache_type_depth() to retrieve the hwloc level depth of
of the given cache depth and type, for instance L1i or L2.
It helps disambiguating the case where hwloc_get_type_depth() returns
HWLOC_TYPE_DEPTH_MULTIPLE.
+ Instruction caches are ignored unless HWLOC_TOPOLOGY_FLAG_ICACHES is
passed to hwloc_topology_set_flags() before load.
+ Add hwloc_ibv_get_device_osdev_by_name() OpenFabrics helper in
openfabrics-verbs.h to find the hwloc OS device object corresponding to
an OpenFabrics device.
* Tools
+ Add lstopo-no-graphics, a lstopo built without graphical support to
avoid dependencies on external libraries such as Cairo and X11. When
supported, graphical outputs are only available in the original lstopo
program.
- Packagers splitting lstopo and lstopo-no-graphics into different
packages are advised to use the alternatives system so that lstopo
points to the best available binary.
+ Instruction caches are enabled in lstopo by default. User --no-icaches
to disable them.
+ Add -t/--threads to show threads in hwloc-ps.
* Removal of obsolete components
+ Remove the old cpuset interface (hwloc/cpuset.h) which is deprecated and
superseded by the bitmap API (hwloc/bitmap.h) since v1.1.
hwloc_cpuset and nodeset types are still defined, but all hwloc_cpuset_*
compatibility wrappers are now gone.
+ Remove Linux libnuma conversion helpers for the deprecated and
broken nodemask_t interface.
+ Remove support for "Proc" type name, it was superseded by "PU" in v1.0.
+ Remove hwloc-mask symlinks, it was replaced by hwloc-calc in v1.0.
* Misc
+ Fix PCIe 3.0 link speed computation.
+ Non-printable characters are dropped from strings during XML export.
+ Fix importing of escaped characters with the minimalistic XML backend.
+ Assert hwloc_is_thissystem() in several I/O related helpers.
+ Fix some memory leaks in the x86 backend for FreeBSD.
+ Minor fixes to ease native builds on Windows.
+ Limit the number of retries when operating on all threads within a
process on Linux if the list of threads is heavily getting modified.
Version 1.4.3

pciutils/libpci is only used if --enable-libpci is given to configure
because its GPL license may taint hwloc. See the Installation section

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.

* Solaris fix for non-contiguous cpu numbers. Thanks to Rolf vandeVaart for
reporting the issue.
* Darwin 10.4 fix. Thanks to Olivier Cessenat for reporting the issue.

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, processing units (logical processors or "threads")
and even I/O devices. hwloc also gathers various attributes such as cache and
memory information, and is portable across a variety of different operating
systems and platforms. Additionally it may assemble the topologies of multiple
machines into a single one so as to let applications consult the topology of an
entire fabric or cluster at once.
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)
* NetBSD
* OSF/1 (a.k.a., Tru64)
* HP-UX
* Microsoft Windows
* IBM BlueGene/Q Compute Node Kernel (CNK)
Since it uses standard Operating System information, hwloc's support is mostly
independant from the processor type (x86, powerpc, ...) and just relies on the
Operating System support. The only exception to this is kFreeBSD, which does
not support topology information, and hwloc thus uses an x86-only CPUID-based
backend (which can be used for other OSes too, see the Components and plugins
section).
To check whether hwloc works on a particular machine, just try to build it and
run lstopo or lstopo-no-graphics. If some things do not look right (e.g. bogus
or missing cache information), see Questions and Bugs below.
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.
Perl bindings are available from Bernd Kallies on CPAN.
Python bindings are available from Guy Streeter:
* Fedora RPM and tarball.
* git tree (html).
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 (usually cairo-devel or libcairo2-dev) can be found in "lstopo" when
hwloc is configured and build.
The hwloc core may also benefit from the following development packages:
* libnuma for memory binding and migration support on Linux (numactl-devel or
libnuma-dev package).
* hwloc can use one of two different libraries for I/O device discovery:
1. libpciaccess (BSD). The relevant development package is usually
libpciaccess-devel or libpciaccess-dev.
2. libpci, from the pciutils package (GPL). The relevant development
package is usually pciutils-devel or libpci-dev.
* the AMD OpenCL implementation for OpenCL device discovery.
* the NVIDIA CUDA Toolkit for CUDA device discovery.
* the NVIDIA Tesla Development Kit for NVML device discovery.
* the NV-CONTROL X extension library (NVCtrl) for NVIDIA display discovery.
* libxml2 for full XML import/export support (otherwise, the internal
minimalistic parser will only be able to import XML files that were
exported by the same hwloc release). See Importing and exporting topologies
from/to XML files for details. The relevant development package is usually
libxml2-devel or libxml2-dev.
* libtool's ltdl library for dynamic plugin loading. The relevant development
package is usually libtool-ltdl-devel or libltdl-dev.
PCI and XML support may be statically built inside the main hwloc library, or
as separate dynamically-loaded plugins (see the Components and plugins
section).
Note that because of the possibility of GPL taint (remember that hwloc is
BSD-licensed), hwloc's configure script will prefer libpciaccess to the
pciutils package. Indeed, if libpciaccess is not found, hwloc will not use
pciutils unless it is specifically requested via the --enable-libpci flag is
provided.
Also note that if you install supplemental libraries in non-standard locations,
hwloc's configure script may not be able to find them without some help. You
may need to specify additional CPPFLAGS, LDFLAGS, or PKG_CONFIG_PATH values on
the configure command line.
For example, if libpciaccess was installed into /opt/pciaccess, hwloc's
configure script may not find it be default. Try adding PKG_CONFIG_PATH to the
./configure command line, like this:
./configure PKG_CONFIG_PATH=/opt/pciaccess/lib/pkgconfig ...

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.

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

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. Also attach the
/proc + /sys tarball generated by the installed script hwloc-gather-topology.sh
when submitting problems about Linux, or send the output of kstat cpu_info in
the Solaris case, or the output of sysctl hw in the Darwin or BSD cases.
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.

# This is the VERSION file for hwloc, describing the precise version
# of hwloc 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=7
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=rc1
# If want_repo_rev=1, then the SVN r number will be included in the overall
# hwloc version number in some form.
want_repo_rev=0
# If repo_rev=-1, then the repository version number 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
# 2) via the "hg -v -R tip" command (if this is a Mercurial clone)
# in the form of "hg<hash>", using the hash tag at the tip
# 3) via the "git log -1" command (if this is a Git clone) in the form
# of "git<hash>", using the hash tag at the HEAD
# 4) with the date (if none of the above work) in the form of
# "date<date>".
#
# Alternatively, if repo_rev is not -1, the value of repo_rev_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, if repo_rev=-1, then its value is replaced
# with the output of "svnversion".
repo_rev=r5771M
# The date when this release was created
date="Aug 29, 2013"
# The shared library version of hwloc's public library. This version
# is maintained in accordance with the "Library Interface Versions"
# chapter from the GNU Libtool documentation. Notes:
# 1. Since version numbers are associated with *releases*, the version
# number maintained on the hwloc SVN trunk (and developer branches) is
# always 0:0:0.
# 2. Version numbers are described in the Libtool current:revision:age
# format.

## Note that this doesn't just cater to obsosete pre-3.x GCC compilers.
## but also to in-use compilers like IMB xlc/xlC and the HP C compiler.
## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

# hwloc note: Per https://svn.open-mpi.org/trac/hwloc/ticket/55, keep
# the environment variable $PKG_CONFIG (vs. renaming it
# $HWLOC_PKG_CONFIG). Short explanation: $PKG_CONFIG is a well-known
# environment variable that can be set by users to override what these
# .m4 macros do. There's no reason we should have a different env
# variable name (e.g., $HWLOC_PKG_CONFIG). So leave it named
# $PKG_CONFIG both here in this specific macro, and all the other
# macros that use it.

# lt~obsolete.m4 -- aclocal satisfying obsolete definitions. -*-Autoconf-*-
#
# Copyright (C) 2004, 2005, 2007, 2009 Free Software Foundation, Inc.
# Written by Scott James Remnant, 2004.
#
# This file is free software; the Free Software Foundation gives
# unlimited permission to copy and/or distribute it, with or without
# modifications, as long as this notice is preserved.
# 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.

Open MPI doesn't need this tree from hwloc. But automake *requires*
that this directory has to be here. So we have an empty directory
with a README in it, a) just to explain why it's here, and b) so that
hg clones won't delete the directory (because it's empty).

/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
The following encoding technique is taken from RFC 1521 by Borenstein
and Freed. It is reproduced here in a slightly edited form for
convenience.
A 65-character subset of US-ASCII is used, enabling 6 bits to be
represented per printable character. (The extra 65th character, "=",
is used to signify a special processing function.)
The encoding process represents 24-bit groups of input bits as output
strings of 4 encoded characters. Proceeding from left to right, a
24-bit input group is formed by concatenating 3 8-bit input groups.
These 24 bits are then treated as 4 concatenated 6-bit groups, each
of which is translated into a single digit in the base64 alphabet.
Each 6-bit group is used as an index into an array of 64 printable
characters. The character referenced by the index is placed in the
output string.
Table 1: The Base64 Alphabet
Value Encoding Value Encoding Value Encoding Value Encoding
0 A 17 R 34 i 51 z
1 B 18 S 35 j 52 0
2 C 19 T 36 k 53 1
3 D 20 U 37 l 54 2
4 E 21 V 38 m 55 3
5 F 22 W 39 n 56 4
6 G 23 X 40 o 57 5
7 H 24 Y 41 p 58 6
8 I 25 Z 42 q 59 7
9 J 26 a 43 r 60 8
10 K 27 b 44 s 61 9
11 L 28 c 45 t 62 +
12 M 29 d 46 u 63 /
13 N 30 e 47 v
14 O 31 f 48 w (pad) =
15 P 32 g 49 x
16 Q 33 h 50 y
Special processing is performed if fewer than 24 bits are available
at the end of the data being encoded. A full encoding quantum is
always completed at the end of a quantity. When fewer than 24 input
bits are available in an input group, zero bits are added (on the
right) to form an integral number of 6-bit groups. Padding at the
end of the data is performed using the '=' character.
Since all base64 input is an integral number of octets, only the
-------------------------------------------------
following cases can arise:
(1) the final quantum of encoding input is an integral
multiple of 24 bits; here, the final unit of encoded
output will be an integral multiple of 4 characters
with no "=" padding,
(2) the final quantum of encoding input is exactly 8 bits;
here, the final unit of encoded output will be two
characters followed by two "=" padding characters, or
(3) the final quantum of encoding input is exactly 16 bits;
here, the final unit of encoded output will be three
characters followed by one "=" padding character.
