Remove stale solaris configure references

[rhc54]

A prior commit (PR #13163) removed the stale Solaris components as we no longer support that environment. However, the PR left the Solaris configure references in the code base.

This PR removes those references. It also removes a duplicate m4 file (opal_check_os_flavors.m4) that exists in the OAC configure area. All references to the OPAL version have been updated to OAC.

Not sure the failure has anything to do with this PR - the singleton test is timing out. I do see the following:

testHIndexed (test_util_dtlib.TestUtilDTLib.testHIndexed) ... �20 more processes
have sent help message help-mca-bml-r2.txt / unreachable proc

Any ideas?

This was not a typo. The compiler emitted a warning about unknown flags hreads, because the t was consumed as part of the -mt parsing.

[rhc54]

Done - I put quotes around the word so it is a little more obviously intentional.

Something is messed up in your main branch - I'm seeing a bunch of errors like this one:

testCreateGroup (test_exceptions.TestExcSession.testCreateGroup) ... --------------------------------------------------------------------------
Your application has invoked an MPI function that is not supported in
this environment.

  MPI function: MPI_Group_from_session_pset
  Reason:       PMIx server unreachable
--------------------------------------------------------------------------

Looks like you are trying to test comm_spawn related functions and the "mpirun" server isn't getting spawned for some reason. The tests don't always just fail - you get lots of "proc not reachable" for the child job. Since it takes time for all those individual comm_spawn tests to fail, the overall CI test eventually times out.

Again, I can't see how this is related to what is being done here. Did something sneak into your main branch?

This is expected behavior. Nothing to do at all with spawning processes. Just no server to handle pmix group construct ops.

Okay - so how do you guys get this CI to pass? I didn't touch the yaml file.

Check the mpi4py testcreatefromgroup unit test. That’s where the exception is special cased.

[rhc54]

Just running it by hand, the problem is that mpi4py is running a bunch of singleton comm_spawn tests - and those are generating errors and an eventual hang. Here is a sample of them:

testArgsOnlyAtRoot (test_spawn.TestSpawnSingleWorld.testArgsOnlyAtRoot) ... 64 more processes have sent help message help-mca-bml-r2.txt / unreachable proc
testCommSpawn (test_spawn.TestSpawnSingleWorldMany.testCommSpawn) ... ERROR
testErrcodes (test_spawn.TestSpawnSingleWorldMany.testErrcodes) ... ERROR
testNoArgs (test_spawn.TestSpawnSingleWorldMany.testNoArgs) ... ERROR
testToMemory (test_status.TestStatus.testToMemory) ... ERROR
test_util_dtlib (unittest.loader._FailedTest.test_util_dtlib) ... ERROR

and here is the traceback for the test that eventually hangs - note that it has called spawn 40 times!

test_apply (test_util_pool.TestProcessPool.test_apply) ... 17 more processes have sent help message help-mca-bml-r2.txt / unreachable proc

[rhc-node01:10447] dpm_disconnect_init: error -12 in isend to process 0

...bunch of error outputs like the one below:

--------------------------------------------------------------------------
At least one pair of MPI processes are unable to reach each other for
MPI communications.  This means that no Open MPI device has indicated
that it can be used to communicate between these processes.  This is
an error; Open MPI requires that all MPI processes be able to reach
each other.  This error can sometimes be the result of forgetting to
specify the "self" BTL.

  Process 1 ([[24043,0],0]) is on host: rhc-node01
  Process 2 ([[51572,40],0]) is on host: rhc-node01
  BTLs attempted: self sm smcuda

Your MPI job is now going to abort; sorry.
