Hi,
I have installed openmpi-dev-4691-g277c319 on my "SUSE Linux
Enterprise Server 12 (x86_64)" with Sun C 5.14 beta and gcc-6.1.0.
Unfortunately I get an internal error for all my spawn programs.
loki spawn 147 ompi_info | grep -e "Open MPI repo revision" -e "C compiler
absolute"
Open MPI repo revision: dev-4691-g277c319

loki spawn 148
loki spawn 151 mpiexec -np 1 --host loki --slot-list 0:0-5,1:0-5 spawn_master
Parent process 0 running on loki
I create 4 slave processes

--------------------------------------------------------------------------
At least one pair of MPI processes are unable to reach each other for
MPI communications. This means that no Open MPI device has indicated
that it can be used to communicate between these processes. This is
an error; Open MPI requires that all MPI processes be able to reach
each other. This error can sometimes be the result of forgetting to
specify the "self" BTL.
Process 1 ([[46948,1],0]) is on host: loki

Your MPI job is now going to abort; sorry.

I would be grateful, if somebody can fix the problem. Thank you
very much for any help in advance.
Kind regards
