+Introduction
+
+The Hardware Locality (hwloc) software project aims at easing the process of
+discovering hardware resources in parallel architectures. It offers
+command-line tools and a C API for consulting these resources, their locality,
+attributes, and interconnection. 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.
+
+hwloc is actually made of two subprojects distributed together:
+
+  * The original hwloc project for describing the internals of computing nodes.
+ It is described in details starting at section Hardware Locality (hwloc)
+ Introduction.
+  * The network-oriented companion called netloc (Network Locality), described
+ in details starting with section Network Locality (netloc).
+
+See also the Related pages tab above for links to other sections.
+
+Netloc may be disabled, but the original hwloc cannot. Both hwloc and netloc
+APIs are documented after these sections.
+
+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.
+
+Basic Installation
+
+Installation is the fairly common GNU-based process:
+
+shell$ ./configure --prefix=...
+shell$ make
+shell$ make install
+
+hwloc- and netloc-specific configure options and requirements are documented in
+sections hwloc Installation and Netloc Installation respectively.
+
+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 ...
+
+Running the "lstopo" tool is a good way to check as a graphical output whether
+hwloc properly detected the architecture of your node. Netloc command-line
+tools can be used to display the network topology interconnecting your nodes.
+
+Installing from a Git clone
+
+Additionally, the code can be directly cloned from Git:
+
+shell$ git clone https://github.com/open-mpi/hwloc.git
+shell$ cd hwloc
+shell$ ./autogen.sh
+
+Note that GNU Autoconf >=2.63, Automake >=1.11 and Libtool >=2.2.6 are required
+when building from a Git clone.
+
+Nightly development snapshots are available on the web site, they can be
+configured and built without any need for Git or GNU Autotools.
+
+Questions and Bugs
+
+Bugs should be reported in the tracker (https://github.com/open-mpi/hwloc/
+issues). Opening a new issue automatically displays lots of hints about how to
+debug and report issues.
+
+Questions may be sent to the users or developers mailing lists (http://
+www.open-mpi.org/community/lists/hwloc.php).
+
+There is also a #hwloc IRC channel on Freenode (irc.freenode.net).
+
+
+
+See https://www.open-mpi.org/projects/hwloc/doc/ for more hwloc documentation.

+/** \defgroup hwlocality_bitmap The bitmap API
+ *
+ * The ::hwloc_bitmap_t type represents a set of integers (positive or null).
+ * A bitmap may be of infinite size (all bits are set after some point).
+ * A bitmap may even be full if all bits are set.
+ *
+ * Bitmaps are used by hwloc for sets of OS processors
+ * (which may actually be hardware threads) as by ::hwloc_cpuset_t
+ * (a typedef for ::hwloc_bitmap_t), or sets of NUMA memory nodes
+ * as ::hwloc_nodeset_t (also a typedef for ::hwloc_bitmap_t).
+ * Those are used for cpuset and nodeset fields in the ::hwloc_obj structure,
+ * see \ref hwlocality_object_sets.
+ *
+ * <em>Both CPU and node sets are always indexed by OS physical number.</em>
+ * However users should usually not build CPU and node sets manually
+ * (e.g. with hwloc_bitmap_set()).
+ * One should rather use existing object sets and combine them with
+ * hwloc_bitmap_or(), etc.
+ * For instance, binding the current thread on a pair of cores may be performed with:
+ * \code
+ * hwloc_obj_t core1 = ... , core2 = ... ;
+ * hwloc_bitmap_t set = hwloc_bitmap_alloc();
+ * hwloc_bitmap_or(set, core1->cpuset, core2->cpuset);
+ * hwloc_set_cpubind(topology, set, HWLOC_CPUBIND_THREAD);
+ * hwloc_bitmap_free(set);
+ * \endcode
+ *
+ * \note Most functions below return an int that may be negative in case of
+ * error. The usual error case would be an internal failure to realloc/extend
+ * the storage of the bitmap (\p errno would be set to \c ENOMEM).
+ *
+ * \note Several examples of using the bitmap API are available under the
+ * doc/examples/ directory in the source tree.
+ * Regression tests such as tests/hwloc/hwloc_bitmap*.c also make intensive use
+ * of this API.

+/** \defgroup hwlocality_shmem Sharing topologies between processes
+ *
+ * These functions are used to share a topology between processes by
+ * duplicating it into a file-backed shared-memory buffer.
+ *
+ * The master process must first get the required shared-memory size
+ * for storing this topology with hwloc_shmem_topology_get_length().
+ *
+ * Then it must find a virtual memory area of that size that is available
+ * in all processes (identical virtual addresses in all processes).
+ * On Linux, this can be done by comparing holes found in /proc/\<pid\>/maps
+ * for each process.
+ *
+ * Once found, it must open a destination file for storing the buffer,
+ * and pass it to hwloc_shmem_topology_write() together with
+ * virtual memory address and length obtained above.
+ *
+ * Other processes may then adopt this shared topology by opening the
+ * same file and passing it to hwloc_shmem_topology_adopt() with the
+ * exact same virtual memory address and length.
+ *
+ * @{

+/* (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.

+
+   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.
