On some OSs (e.g., Ubuntu 14.04.2 LTS), the linker is configured such
that the symbols of library dependencies are not available to the
application. Hence, we need to explicitly list such dependencies when
creating the executable.
For this commit, these tests are use OPAL function calls, so we must
explicitly link in libopen-pal.so.
- make the internal structure follow the Open MPI naming convention
- provide a single flag/macro which controls the compilation/utilization of this
feature, to avoid that somebody using this has to modify every single
fcoll component. A configure option could be added later if desired.
this test seems broken :
- some false positive were reported
- it fails to detect some OFED version mismatch
this commit simply removes this test, which means the application
will likely fail if XRC is used ad OFED version is different
between compile time and runtime
configury: fix hcoll, fca and mxm detection and revamp yalla Makefile.am
Thanks to David Shrader and Ake Sandgren for bringing this issue to our attention
* do not add -I/.../include/fca -I /.../include/fca_core to CPPFLAGS
* allow configure --with-fca
* search fca libs in both DIR/lib and DIR/lib64
* fix the description of the --with-fca option
* do not add -I/.../include/hcoll -I /.../include/hcoll/api to CPPFLAGS
* allow configure --with-hcoll
* search hcoll libs in both DIR/lib and DIR/lib64
* fix the description of the --with-hcoll option
mtl_ofi_provider_include (resp. mtl_ofi_provider_exclude) can be used
to specify which provider(s) the OFI MTL can select (resp. ignore).
e.g. --mca mtl_ofi_provider_include "psm,sockets"
By default, mtl_ofi_provider_exclude is set to "sockets,mxm".
This deprecates the old MCA var named "mtl_ofi_provider".
This commit does the following:
* s/ompi_check_treematch/ompi_topo_treematch/ (i.e., abide by the
prefix rule)
* change the value of ompi_topo_treematch_happy from yes/no to 0/1, so
that we can use -eq for numerical comparisons (vs. string
comparisons). It's the little things in life, no?
* Check the valueo f $OPAL_HAVE_HWLOC to ensure that hwloc support is
enabled. If not, disqualify treematch from building.
* Fixes a few places that were underquoted
* Convert from "test ... -a ..." to "test ... && test ..."

Previously, extensions were required to have a config.h for their C
bindings. This commit allows them to have a config.h.in, in case
their C bindings header file is generated.
* don't pass --tree-spawn to the orted cmd line. If someone doesn't want tree-spawn, it shows up as an MCA param anyway
* ensure state/orted component disqualifies itself from CM operations
* clarify the DVM proc_type definitions
* ensure we stop littering the tmp dir with session directories
The prior code was checking string constants (which are #defines from
configure) against NULL. They can never be NULL, so the checks were
overly-defensive. If the preprocessor macros do not exist, we'll get
a different compiler error. So remove the dead code.
This fixes CID 72349.
This code really had no purpose; just assign FI_VERSION(1, 1). This
fixes CID 1315274.
Also clarify the commet about why we still retain libfabric v1.0.0
compatibility code, even though configure.m4 requires libfabric >= v1.1.0.
In short applications, it's possible that the agent (i.e., local rank
0) will finalize after non-local rank 0 procs detect the connectivity
checker named socket, but before they complete a connect() on it. As
such, their connect() gets ECONNREFUSED.
This commit adds a simple counter in the agent that won't let it quit
before it accept()'s from all local procs, or 10 seconds goes by
(whichever occurs first). This is similar to the timeout for the
clients: they'll exit if they don't see the expected named socket
within 10 seconds.
There's no longer any need for the usnic BTL to have its own progress
thread: it can use the opal_progress_thread() infrastructure. This
commit removes the code to startup/shutdown the usnic-BTL-specific
progress thread and instead, just adds its events to the OPAL-wide
progress thread.
This necessitated a small change in the finalization step.
Previously, we would stop the progress thread and then tear down the
events. We can no longer stop the progress thread, and if we start
tearing down events, this will cause shutdown/hangups to be sent
across sockets, potentially firing some of the still-remaining events
while some (but not all) of the data structures have been torn down.
Chaos ensues.
Instead, queue up an event to tear down all the pending events. Since
the progress thread will only fire one event at a time, having a
teardown event means that it can tear down all the pending events
"atomically" and not have to worry that one of those events will get
fired in the middle of the teardown process.
A helper method in Request.java could cause a crash
if the request array that was passed contained nulls.

This commit rewrites parts of libnbc to fix issues identified by
coverity and myself. The changes are as follows:
- libnbc function would return invalid error codes (internal to
libnbc) to the mpi layer. These codes names are of the form
NBC_. They do not match up with the error codes expected by the mpi
layer. I purged the use of all these error codes with the exception
of NBC_OK and NBC_CONTINUE in progress. These codes are used to
identify when a request handle is complete.
- Handles and schedules were leaked by all collective routines on
error. A new routine was added to return a collective handle
(NBC_Return_handle).
- Temporary buffers containting in/out neighbors for neighborhood
collectives were always leaked.
- Neigborhood collectives contained code to handle MPI_IN_PLACE which
is never a valid input for the send or receive buffer. Stipped this
code out.
- Files were inconsistently named. Most are nbc_isomething.c but one
was named coll_libnbc_ireduce_scatter_block.c.
- Made the NBC_Schedule "structure" and object so it can be
retained/released. This may enable the use of schedule caching at a
later time. More testing will be needed to ensure the caching code
works. If it doesn't the code should be stripped out completely.
- Added code to simply common case of scheduling send/recv +
barrier.
- Code cleanup for readability.
The code now passes the clang static analyzer.
