Hi,
I installed openmpi-1.10.3rc2 on my "SUSE Linux Enterprise Server
12 (x86_64)" with Sun C 5.13 and gcc-6.1.0. Unfortunately I get
a segmentation fault for "--slot-list" for one of my small programs.
loki spawn 119 ompi_info | grep -e "OPAL repo revision:" -e "C compiler
absolute:"
OPAL repo revision: v1.10.2-201-gd23dda8
C compiler absolute: /usr/local/gcc-6.1.0/bin/gcc

-------------------------------------------------------
Child job 2 terminated normally, but 1 process returned
a non-zero exit code.. Per user-direction, the job has been aborted.
-------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus
causing
the job to be terminated. The first process to do so was:
Process name: [[56340,2],0]
Exit code: 1
--------------------------------------------------------------------------
loki spawn 122
I would be grateful, if somebody can fix the problem. Thank you
very much for any help in advance.
Kind regards
