Hi Howard,
Is this new behavior?
Do you see the error if you set PSM_DEVICES=shm,self ? The PSM MTL should be
setting this on its own, but maybe something changed.

Hi,
I'm seeing an issue running various tests from the Intel MPI test suite. Has
anyone else seen this? Any ideas? RHEL7, master git hash
090922887b92c9764cc5, no CFLAGS set, no special configure options. The mpirun
command and output are included below.

Hi,
I've run into a problem with the IMB-RMA exchange_get test. At this point I
suspect it's an issue in Open MPI or the test itself. Could someone take a
look?
I'm running Open MPI 1.8.5 and IMB 4.0.2. MVAPICH2 is able to run all of
IMB-RMA successfully.

Hi Howard,
The PSM MTL sets PSM_EP_OPEN_AFFINITY_SKIP, so if I understand right, OMPI
already has the fix for you.

Is there anything written up about recent Open MPI one-sided work? Looking for
something beyond just the code that I can study up on.. papers, design docs,
future plans, etc.

I care and can attend at that time.

No this is not expected behavior.
The PSM MTL code has not changed in 2 months, when I fixed that unused variable
warning for you. That suggests something above the PSM MTL broke things. I
see no reason your older software install should suddenly stopping working if
all you are updating is

OK, I'm able to reproduce this now, not sure why I couldn't before. I took a
look at the diff of the PSM MTL from 1.6.5 to 1.8.1, and nothing is standing
out to me.
Question more for the general group: Did anything related to the
behavior/usage of MTL add_procs() change in this time window?

Hi,
I'm reporting a performance (message rate 16%, latency 3%) regression when
using PSM that occurred between OMPI v1.6.5 and v1.8.1. I would guess it
affects other networks too, but I haven't tested. The problem stems from the
--enable-smp-locks and --enable-opal-multi-threads options.
Hi Adrian,
I'm unable to reproduce here with OMPI v1.8.3 (I assume you're doing this with
one 8-core node):
$ mpirun -np 32 -mca pml cm -mca mtl psm ./mpi_test_suite -t "environment"
(Rank:0) tst_test_array[0]:Status
(Rank:0) tst_test_array[1]:Request_Null
(Rank:0) tst_test_array[2]:Type_dup
Is there any prior written outline/discussion on this topic that someone could
point me to? Any plans to apply this work to the MTLs as well?
Thanks,
Andrew

Hi,
I'm looking at the OMPI svn mirror on github and there don't appear to be any
release tags for v1.8.x; the most recent appears to be v1.7.2. Are there any
plans to add tags for any more releases?
Thanks,
Andrew
