Replace our old, clunky timing setup with a much nicer one that is only available if configured with --enable-timing. Add a tool for profiling clock differences between the nodes so you can get more precise timing measurements. I'll ask Artem to update the Github wiki with full instructions on how to use this setup.

1. It is not sufficient to put the result of m4_toupper() in a
variable and use that variable as the variable name in
AC_DEFINE_UNQUOTED. Instead, just use m4_toupper() directly in
AC_DEFINE_UNQUOTED. Also, save the result value in a "permanent"
variable that isn't erased, just in case autoconf decides to be lazy
about instantiating the body AC_DEFINE_UNQUOTED and move it later
(this is probably overkill :-) ).
1. Use the OMPI Way of always defining macros (to 0 or 1). Then also
slightly change the logic in util/basename.c to just check
OPAL_HAVE_DIRNAME (because it will always be defined).

When we know that the storage is properly aligned, we can cast the

We used to do this assignment via a union, but clang's

The question of whether or not the openib BTL supports loopback is a separate question. It may be more appropriate to make the modex be PMIX_GLOBAL for cases where openib can support loopback so someone can run without a shared memory component. I'll leave that decision to the IB vendors.

WHAT: Merge the PMIx branch into the devel repo, creating a new
OPAL “lmix” framework to abstract PMI support for all RTEs.
Replace the ORTE daemon-level collectives with a new PMIx
server and update the ORTE grpcomm framework to support
server-to-server collectives
WHY: We’ve had problems dealing with variations in PMI implementations,
and need to extend the existing PMI definitions to meet exascale
requirements.
WHEN: Mon, Aug 25
WHERE: https://github.com/rhc54/ompi-svn-mirror.git
Several community members have been working on a refactoring of the current PMI support within OMPI. Although the APIs are common, Slurm and Cray implement a different range of capabilities, and package them differently. For example, Cray provides an integrated PMI-1/2 library, while Slurm separates the two and requires the user to specify the one to be used at runtime. In addition, several bugs in the Slurm implementations have caused problems requiring extra coding.
All this has led to a slew of #if’s in the PMI code and bugs when the corner-case logic for one implementation accidentally traps the other. Extending this support to other implementations would have increased this complexity to an unacceptable level.
Accordingly, we have:
* created a new OPAL “pmix” framework to abstract the PMI support, with separate components for Cray, Slurm PMI-1, and Slurm PMI-2 implementations.
* Replaced the current ORTE grpcomm daemon-based collective operation with an integrated PMIx server, and updated the grpcomm APIs to provide more flexible, multi-algorithm support for collective operations. At this time, only the xcast and allgather operations are supported.
* Replaced the current global collective id with a signature based on the names of the participating procs. The allows an unlimited number of collectives to be executed by any group of processes, subject to the requirement that only one collective can be active at a time for a unique combination of procs. Note that a proc can be involved in any number of simultaneous collectives - it is the specific combination of procs that is subject to the constraint
* removed the prior OMPI/OPAL modex code
* added new macros for executing modex send/recv to simplify use of the new APIs. The send macros allow the caller to specify whether or not the BTL supports async modex operations - if so, then the non-blocking “fence” operation is used, if the active PMIx component supports it. Otherwise, the default is a full blocking modex exchange as we currently perform.
* retained the current flag that directs us to use a blocking fence operation, but only to retrieve data upon demand

Thanks to Ashley Pittman for pointing the modex should now be zero'ed

It turns out that we ''can'' get to the endpoint destructor with the
endpoint still on the "endpoints needing ACKs" list. So if it's on
the list, remove it first, and then DESTRUCT the opal_list_item_t.
This prevents an assert() fail in debug builds. We'd like to let this
soak over the weekend.

Rarely -- but it happens -- the connectivity client gets ECONNREFUSED
because the connectivity agent listen() backlog is too small. Rather
than put in a loop on the client side, take the simple way out for
now: increase the backlog size to an arbitrarily-large number.

The _strdup usage in opal/util/basename looks like it was a product of
Windows compatibility (see r11336), which we don't care about any
more. Further, opal/win32/win_compat.h, which we sitll maintain for
cygwin compatibility, #define's strdup to _strdup (which is what
Microsoft wants you to use).
So this old _strdup in opal/util/basename.c (and its corresponding
check in configure.ac) should just be removed.

This commit was SVN r32449.
In core library portions of the configury (e.g., top-level
configure.ac itself), we were calling AC_CHECK_LIB and
OPAL_CHECK_FUNC_LIB to check for various libraries.
'''SIDENOTE:''' It turns out that modern Autoconf has AC_SEARCH_LIBS,
which does just about exactly what OPAL_CHECK_FUNC_LIB does. So this
commit effectively replaces OPAL_CHECK_FUNC_LIB with AC_SEARCH_LIBS.
However, we never bothered to add these found libraries to the wrapper
compiler list of libraries used for static linking (doh!). We've been
getting lucky for quite a while that components were adding the same
libraries to their wrapper compiler LIBS list.
This is problematic, however, if we don't build some of these
components. For example, Paul Hargrove noticed that if he configured
with --disable-shared --enable-static --disable-io-romio, ROMIO was no
longer adding some libraries to the wrapper LIBS list -- libraries
that just happened to also be needed by core OPAL/ORTE/OMPI layers.
The solution is not to use AC_CHECK_LIB or OPAL_CHECK_FUNC_LIB, but
use a pair of new macros:
* OPAL_SEARCH_LIBS_CORE: a wrapper around AC_SEARCH_LIBS. If we add
something to $LIBS, then also add it to the wrapper list of static
libraries. This is the main piece of functionality that was
wrong/missing.
* OPAL_SEARCH_LIBS_COMPONENT: similar to OPAL_SEARCH_LIBS_CORE, but
instead of directly adding it to the wrapper list of static
libaries, add it to <framework>_<component>_LIBS (which eventually
gets slurped up into the wrapper list of static libraries. See the
lengthy comment in config/opal_setup_wrappers.m4 near the beginning
of OPAL_SETUP_WRAPPER_INIT() for a more detailed explanation).
Most components did this correctly already, but one or two weren't
right, so I implemented this second macro quite similar to the
first and put it everywhere we already used AC_SEARCH_LIBS or
OPAL_CHECK_FUNC_LIB.
This needs to soak for a day or two on the trunk before moving to the
v1.8 branch.
