[OMPI users] mpirun hangs

[Mota, Thyago]

Hello.

I have openmpi 2.0.4 installed on a Cent OS 7. When I try to run "mpirun"
it *hangs*. Below is the output I get using the debug option:

$ mpirun -d

[elm:07778] procdir: /tmp/openmpi-sessions-***@elm_0/12011/0/0

[elm:07778] jobdir: /tmp/openmpi-sessions-***@elm_0/12011/0

[elm:07778] top: openmpi-sessions-***@elm_0

[elm:07778] tmp: /tmp

[elm:07778] sess_dir_cleanup: job session dir does not exist

[elm:07778] procdir: /tmp/openmpi-sessions-***@elm_0/12011/0/0

[elm:07778] jobdir: /tmp/openmpi-sessions-***@elm_0/12011/0

[elm:07778] top: openmpi-sessions-***@elm_0

[elm:07778] tmp: /tmp

If I use "strace mpirun" I get the following lines at the end.

mprotect(0x7f173c619000, 4096, PROT_READ) = 0

munmap(0x7f173cae5000, 2114000) = 0

munmap(0x7f173c8e0000, 2114264) = 0

munmap(0x7f173c3c3000, 2466952) = 0

futex(0x7f1741f1aa00, FUTEX_LOCK_PI, 1, NULL) = -1 ESRCH (No such process)

pause(

Any idea what could be causing the problem?

Thanks.

There can be lots of reasons that this happens. Can you send all the information listed here?

Sorry; I'm still not clear on exactly what you are trying to do, or how it is failing for you. Your copy-n-pasted output in the first mail appeared to be incorrect -- there was no command on the mpirun command line, and the strace output appears to be truncated.

Are you only running on a single node? Are you able to run hostname(1), or the MPI "hello world" or "ring" applications?

Can you upgrade to a newer version of Open MPI? 2.0.x is very old -- 3.1.0 is the most recent.
