Hi,
I've tried to install openmpi-v2.0.x-201709300323-7b3806e on my "SUSE Linux
Enterprise Server 12.2 (x86_64)" with Sun C 5.15 (Oracle Developer Studio
12.6). Unfortunately I still get the following error that I reported some
time ago.
loki openmpi-v2.0.x-201709300323-7b3806e-Linux.x86_64.64_c

I think he cited a typo in his email. The actual file he is referring to is
-
$ find . -name pmix_mmap.c
./opal/mca/pmix/pmix2x/pmix/src/sm/pmix_mmap.c
-
From his log file, there appear to be two problems:
-
sm/pmix_mmap.c(66): warning #266: function "posix_fallocate" dec
I correctly understood the file and the errors. I’m just pointing out that the
referenced file cannot possibly contain a pointer to opal/threads/condition.h.
There is no include in that file that can pull in that path.

I think that file does get included indirectly, but the real issue is the old
Intel compiler not supporting (struct argparse). I.e., the solution might well
be "use a newer compiler."

Update... Problem of all processes runing on first node (oversubscribed
dual-core machine) is NOT resolved.
Changing the mpirun command in the Torque batch script ("pbs_hello" - See
previous) to
mpirun --nooversubscribe --display-allocation hostname
Then submitting to PBS/Torque using
qs
One thing I can see is that the local host (where mpirun executed) shows as
“node21” in the allocation, while all others show their FQDN. This might be
causing some confusion.
You might try adding "--mca orte_keep_fqdn_hostnames 1” to your cmd line and
see if that helps.

I noticed that too. Though the submitting host for torque is a different
host (main head node, "shrek"), "node21" is the host that torque runs the
batch script (and the mpirun command) it being the first node in the
"dualcore" resource group.
Adding option...
It fixed the hostname in the alloca
Anthony,
in your script, can you
set -x
env
pbsdsh hostname
mpirun --display-map --display-allocation --mca ess_base_verbose 10
--mca plm_base_verbose 10 --mca ras_base_verbose 10 hostname
and then compress and send the output ?
Cheers,

The stdin and stdout are saved to separate channels.
It is interesting that the output from pbsdsh is node21.emperor 5 times,
even though $PBS_NODES is the 5 individual nodes.
Attached are the two compressed files, as well as the pbs_hello batch used.

Anthony,
we had a similar issue reported some times ago (e.g. Open MPI ignores
torque allocation),
and after quite some troubleshooting, we ended up with the same behavior
(e.g. pbsdsh is not working as expected).
