8d161af059 Move hwloc_cpuset_t prettyprint routines down into the hwloc base:
* opal_hwloc_base_cset2str(): Make a human-readable string of a
   hwloc_cpuset_t (e.g., socket 2[core 3[hwt 1]])
 * opal_hwloc_base_cset2mapstr(): Make a map-like string of a
   hwloc_cpuset_t (e.g., [B./..])

9c9d7e77df Commit a fix for hwloc -- still checking with upstream to see if this
will be the final solution.  But I'm committing it now so that
Oracle's Solaris Studio builds can resume.

The issue is that the C++ bindings are now (eventually) including
<hwloc.h>.  We use !__hwloc_inline__ and #define it to an appropriate
value at compile-time.  The issue is that when we're compiling C++
code, we should just set !__hwloc_inline__ to "inline", because that's
a keyword in the C++ language (as opposed to !__inline__, or
somesuch).

de4bbacd13 It turns out that we can't always include the hwloc OpenFabrics verbs
helper file, even if we find that the system has <infiniband/verbs.h>.
The reason is because there are some inline functions in that verbs
helper file that invoke ibv_* functions.  Some linkers (e.g., Solaris
Studio Compilers) will instantiate those static inline functions --
even if we don't use them -- and therefore we need to be able to
resolve the ibv_* symbols at link time.

But since -libverbs is only specified in places where we use other
ibv_* functions (e.g., the OpenFabrics-based BTLs), that means that
linking random executables can/will fail (e.g., orterun).

So instead, introduce a new #define: OPAL_HWLOC_WANT_VERBS_HELPER.  If
this macro is set to 1 before including opal/mca/hwloc/hwloc.h, then
you'll also get the hwloc OpenFabrics verbs helper header file (*if*
hwloc found <infiniband/verbs.h> -- otherwise, it'll #error).

2ba10c37fe Per RFC, bring in the following changes:
* Remove paffinity, maffinity, and carto frameworks -- they've been
   wholly replaced by hwloc.
 * Move ompi_mpi_init() affinity-setting/checking code down to ORTE.
 * Update sm, smcuda, wv, and openib components to no longer use carto.
   Instead, use hwloc data.  There are still optimizations possible in
   the sm/smcuda BTLs (i.e., making multiple mpools).  Also, the old
   carto-based code found out how many NUMA nodes were ''available''
   -- not how many were used ''in this job''.  The new hwloc-using
   code computes the same value -- it was not updated to calculate how
   many NUMA nodes are used ''by this job.''
   * Note that I cannot compile the smcuda and wv BTLs -- I ''think''
     they're right, but they need to be verified by their owners.
 * The openib component now does a bunch of stuff to figure out where
   "near" OpenFabrics devices are.  '''THIS IS A CHANGE IN DEFAULT
   BEHAVIOR!!''' and still needs to be verified by OpenFabrics vendors
   (I do not have a NUMA machine with an OpenFabrics device that is a
   non-uniform distance from multiple different NUMA nodes).
 * Completely rewrite the OMPI_Affinity_str() routine from the
   "affinity" mpiext extension.  This extension now understands
   hyperthreads; the output format of it has changed a bit to reflect
   this new information.
 * Bunches of minor changes around the code base to update names/types
   from maffinity/paffinity-based names to hwloc-based names.
 * Add some helper functions into the hwloc base, mainly having to do
   with the fact that we have the hwloc data reporting ''all''
   topology information, but sometimes you really only want the
   (online | available) data.

aba398ce09 Per RFC
(http://www.open-mpi.org/community/lists/devel/2012/04/10905.php), set
opal_cache_line_size via hwloc data, if we have it.
opal_cache_line_size will be set to an hwloc-inspired value by the end
of orte_init(), but will always have a safe value to use (i.e., a
default value 128) -- even before opal_init() has completed.

Default to the same value of 128 that Open MPI has used for several
years if a) we have no hwloc data, or b) we weren't able to find L2
objects in the hwloc data.

d30bbc2ef9 Fix an old issue: enable hwloc PCI detection except on SuSE 10 64 bit.
Worked with Oracle to verify that hwloc PCI detection is correctly
disabled on the Suse 10/64 bit platform and is enabled by default on
all other platforms.  The --[en|dis]able-hwloc-pci switch is also
available for manual override of the configure decision about hwloc
PCI support.

f84c16bb65 Fixes trac:3043. Looks like some of the improvements to the hwloc132
hwloc component weren't reverse applied to the external hwloc
component.  Additionaly, if we add stuff to LDFLAGS/LIBS, we also may
need to append (DY)LD_LIBRARY_PATH (here in this configure process
only), otherwise future configure tests may fail because they can't
find libhwloc.so (e.g., if you --with-hwloc=/some/path, we need to add
/some/path/lib to (DY)LD_LIBRARY_PATH).

534d70025f Cleanup the detection of process binding during mpi_init. There are several cases that need to be checked:
1. no binding support - indicated by a negative return code from get_cpubind

2. binding supported, but not bound - the bitset returned by get_cpubind is the same as the available cpuset

3. binding supported and bound - bitset from get_cpubind is a subset of available cpuset

4. only one cpu is available - in this case, get_cpubind matches the available cpuset, but we are effectively bound

7f9ae11faf Per http://www.open-mpi.org/community/lists/users/2011/11/17862.php,
to make MPI_IN_PLACE (and other sentinel Fortran constants) work on OS
X, we need to use the following compiler (linker) flag:

    -Wl,-commons,use_dylibs 

So if we're compiling on OS X, test to see if that flag works with the
compiler.  If so, add it to the wrapper FFLAGS and FCFLAGS (note that
per a future update, we'll only have one Fortran compiler anyway).

Fixes trac:1982.

6310361532 At long last, the fabled revision to the affinity system has arrived. A more detailed explanation of how this all works will be presented here:
https://svn.open-mpi.org/trac/ompi/wiki/ProcessPlacement

The wiki page is incomplete at the moment, but I hope to complete it over the next few days. I will provide updates on the devel list. As the wiki page states, the default and most commonly used options remain unchanged (except as noted below). New, esoteric and complex options have been added, but unless you are a true masochist, you are unlikely to use many of them beyond perhaps an initial curiosity-motivated experimentation.

In a nutshell, this commit revamps the map/rank/bind procedure to take into account topology info on the compute nodes. I have, for the most part, preserved the default behaviors, with three notable exceptions:

1. I have at long last bowed my head in submission to the system admin's of managed clusters. For years, they have complained about our default of allowing users to oversubscribe nodes - i.e., to run more processes on a node than allocated slots. Accordingly, I have modified the default behavior: if you are running off of hostfile/dash-host allocated nodes, then the default is to allow oversubscription. If you are running off of RM-allocated nodes, then the default is to NOT allow oversubscription. Flags to override these behaviors are provided, so this only affects the default behavior.

2. both cpus/rank and stride have been removed. The latter was demanded by those who didn't understand the purpose behind it - and I agreed as the users who requested it are no longer using it. The former was removed temporarily pending implementation.

3. vm launch is now the sole method for starting OMPI. It was just too darned hard to maintain multiple launch procedures - maybe someday, provided someone can demonstrate a reason to do so.

As Jeff stated, it is impossible to fully test a change of this size. I have tested it on Linux and Mac, covering all the default and simple options, singletons, and comm_spawn. That said, I'm sure others will find problems, so I'll be watching MTT results until this stabilizes.

b44f8d4b28 Complete implementation of the ess.proc_get_locality API. Up to this point, the API was only capable of telling if the specified proc was sharing a node with you. However, the returned value was capable of telling you much more detailed info - e.g., if the proc shares a socket, a cache, or numa node. We just didn't have the data to provide that detail.
Use hwloc to obtain the cpuset for each process during mpi_init, and share that info in the modex. As it arrives, use a new opal_hwloc_base utility function to parse the value against the local proc's cpuset and determine where they overlap. Cache the value in the pmap object as it may be referenced multiple times.

Thus, the return value from orte_ess.proc_get_locality is a 16-bit bitmask that describes the resources being shared with you. This bitmask can be tested using the macros in opal/mca/paffinity/paffinity.h

951c745590 We always have hwloc xml support (now that it's built into to hwloc
without needing libxml2).  So OPAL_HAVE_HWLOC_XML is no longer
necessary.

970a75a7b6 Update to a custom OMPI roll of hwloc v1.2.2. Upgrade the configry to
match similar stuff in the event framework; only add CPPFLAGS /
LDFLAGS / LIBS / and WRAPPER_EXTRA_* of the same for the one, single,
winning component (because this framework is compile-time,
one-of-many).

82c93611e6 Fix some problems with the libevent and hwloc frameworks:
* change components from setting <framework>_base_include to
   opal_<framework>_<component>_include; the framework m4 will figure
   out the winning component and pick the right "include" shell
   variable.  Ditto for the other shell variables (cppflags, ldflags,
   etc.). 
 * misc fixes to hwloc/external
 * add a bunch of missing "opal_" prefixes to shell variables
 * add a few more / update a few comments in framework m4's

51129cc2a8 If built without hwloc xml support, we cannot currently pass the local topology from the daemon to an MPI app. This makes it impossible to set affinity, for example. In this case, have the app get its own copy of the topology at startup.
For safety sake, protect hwloc-based affinity modules from NULL topology

9db4542c2b Move maffinity_base_alloc_policy and
maffinity_base_bind_failure_action MCA params to the hwloc base
(hwloc_base_alloc_polocy and hwloc_base_bind_failure_action).  Since
these MCA parameters were never on a release branch, I'm just
moving/renaming them outright and not leaving aliases to the old
names.

Note that some upper layer needs to call
opal_hwloc_base_set_process_membind_policy() to set the
set-by-MCA-param process-wide memory affinity policy.  We can't do
this automatically during hwloc_base_open() because, for reasons
described elsewhere, opal_hwloc_topology is not automatically filled
during hwloc_base_open() (in short: potential scalability issues when
launching many MPI processes simultaneously on a single machine, for
example).

4771c36061 * With some m4 trickery, if no form of --with-hwloc is specified on
the command line, hwloc is just like any other external dependency
   in OMPI: if we find it, we'll use it. If we don't find it, we'll
   ignore it.  See comments in opal/mca/hwloc/configure.m4 for an
   explanation. 
 * Fix some copy-n-paste errors in opal/mca/hwloc/configure.m4
   w.r.t. flags coming in from the winning component.
 * Add another line in ompi_info's output about whether hwloc support
   is included or not.

92c7372e20 Per the RFC from Jeff, move hwloc from opal/mca/common to its own static framework ala libevent. Have ORTE daemons collect the topology info at startup and, if --enable-hwloc-xml is set, send that info back to the HNP for later use. The HNP only retains unique topology "templates" to reduce memory footprint. Have the daemon include the local topology info in the nidmap buffer sent to each app so the apps don't all hammer the local system to discover it for themselves.
Remove the sysinfo framework as hwloc replaces that functionality.
