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.
