Hi OMPI_Developers,
It seems that I am unable to establish an MPI communication between two
independently started MPI programs using the simplest client/server call
sequence I can imagine (see the two attached files) when the client and server
process are started on different machines. Note tha
Try running it with “—mca oob_base_verbose 100” on both client and server - it
will tell us why the connection was refused.

Thanks Ralph for this quick response.
In the two attachements you will find the output I got when running the
following commands:
[audet@fn1 mpi]$ mpiexec --mca oob_base_verbose 100 -n 1 ./simpleserver 2>&1 |
tee server_out.txt
[audet@linux15 mpi]$ mpiexec --mca oob_base_verbose 100 -n 1 ./sim
I see the problem - it’s a race condition, actually. I’ll try to provide a
patch for you to test, if you don’t mind.
