Yes. I have implemented more or less the same program in C and Java.
tyr hello_1 131 mpiexec -np 2 -host linpc0,linpc1 hello_1_mpi
Process 0 of 2 running on linpc0
Process 1 of 2 running on linpc1
Now 1 slave tasks are sending greetings.
Greetings from task 1:
message type: 3
msg length: 132 characters
message:
hostname: linpc1
operating system: Linux
release: 3.1.10-1.16-desktop
processor: x86_64
tyr hello_1 132 mpiexec -np 2 -host linpc0,linpc1 java HelloMainWithBarrier

It looks like opal_init failed for some reason; your parallel process is
likely to abort. There are many reasons that a parallel process can
fail during opal_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):
mca_base_open failed
--> Returned value -2 instead of OPAL_SUCCESS
...
Thank you very much for any help in advance.
Kind regards
Siegmar
