Hi,
I have installed openmpi-2.0.2rc2 on my "SUSE Linux Enterprise
Server 12 (x86_64)" with Sun C 5.14 beta and gcc-6.2.0. Unfortunately,
I get an error when I run one of my programs. Everything works as
expected with openmpi-master-201612232109-67a08e8. The program
gets a timeout with openmpi-v2.x-201612232156-5ce66b0.
loki spawn 144 ompi_info | grep -e "Open MPI:" -e "C compiler absolute:"
Open MPI: 2.0.2rc2
C compiler absolute: /opt/solstudio12.5b/bin/cc
loki spawn 145 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

A system call failed during shared memory initialization that should
not have. It is likely that your MPI job will now either abort or
experience performance degradation.
Local host: loki
System call: open(2)
Error: No such file or directory (errno 2)

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 ([[55817,2],0]) is on host: loki
Process 2 ([[55817,2],1]) is on host: unknown!
BTLs attempted: self sm tcp vader
Your MPI job is now going to abort; sorry.

It looks like MPI_INIT failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during MPI_INIT; some of which are due to configuration or environment
problems. This failure appears to be an internal failure; here's some
additional information (which may only be relevant to an Open MPI
developer):
ompi_dpm_dyn_init() failed
--> Returned "Unreachable" (-12) instead of "Success" (0)

very much for any help in advance.
