@@ -8,66 +12,450 @@ 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:
+hwloc provides command line tools and a C API to obtain the hierarchical map of
+key computing elements within a node, such as: NUMA memory nodes, shared
+caches, processor packages, dies and 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.
 
-  * 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).
+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.
 
-See also the Related pages tab above for links to other sections.
+hwloc supports the following operating systems:
 
-Netloc may be disabled, but the original hwloc cannot. Both hwloc and netloc
-APIs are documented after these sections.
+  * Linux (with knowledge of cgroups and cpusets, memory targets/initiators,
+ etc.) on all supported hardware, including Intel Xeon Phi, ScaleMP vSMP,
+ and NumaScale NumaConnect.
+  * Solaris (with support for processor sets and logical domains)
+  * AIX
+  * Darwin / OS X
+  * FreeBSD and its variants (such as kFreeBSD/GNU)
+  * NetBSD
+  * HP-UX
+  * Microsoft Windows
+  * IBM BlueGene/Q Compute Node Kernel (CNK)
 
-Installation
+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 main exception is BSD operating systems (NetBSD,
+FreeBSD, etc.) because they do not provide support topology information, hence
+hwloc uses an x86-only CPUID-based backend (which can be used for other OSes
+too, see the Components and plugins section).
 
-hwloc (https://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 (https:/
-/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.
+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.
 
-Basic Installation
+hwloc only reports the number of processors on unsupported operating systems;
+no topology information is available.
 
-Installation is the fairly common GNU-based process:
+For development and debugging purposes, hwloc also offers the ability to work
+on "fake" topologies:
 
-shell$ ./configure --prefix=...
-shell$ make
-shell$ make install
+  * Symmetrical tree of resources generated from a list of level arities, see
+ Synthetic topologies.
+  * Remote machine simulation through the gathering of topology as XML files,
+ see Importing and exporting topologies from/to XML files.
 
-hwloc- and netloc-specific configure options and requirements are documented in
-sections hwloc Installation and Netloc Installation respectively.
+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, LaTeX tikzpicture, PDF, PNG, and FIG (see Command-line Examples
+below). Note that some of the export formats require additional support
+libraries.
 
-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.
+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.
 
-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:
+Bindings for several other languages are available from the project website.
 
-./configure PKG_CONFIG_PATH=/opt/pciaccess/lib/pkgconfig ...
+Command-line Examples
 
-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.

+Programming Interface
+
+The basic interface is available in hwloc.h. Some higher-level functions are
+available in hwloc/helper.h to reduce the need to manually manipulate objects
+and follow links between them. Documentation for all these is provided later in
+this document. Developers may also want to look at hwloc/inlines.h which
+contains the actual inline code of some hwloc.h routines, and at 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 Git clone, 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
+
+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.
+
+Similarly, the ability of reporting topology information varies from one
+platform to another. As shown in Command-line 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 8 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, packages, or cores is available.
+
+Here's the graphical output from lstopo on this platform when Simultaneous
+Multi-Threading (SMT) is enabled:
+
+[ppc64-with]
+
+And here's the graphical output from lstopo on this platform when SMT is
+disabled:
+
+[ppc64-with]
+
+Notice that hwloc only sees half the PUs when SMT is disabled. PU L#6, 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 (see
+also Logical index in Indexes and Sets). Hence, PU L#6 in the SMT-disabled
+picture probably corresponds to PU L#12 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]
+
+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, a new element may someday exist between a
+core and a PU.

+hwloc is the evolution and merger of the libtopology project and the Portable
+Linux Processor Affinity (PLPA) (https://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
