Hi,
I am getting a "oob-tcp: Communication retries exceeded" error
message when I run a 238 MPI slave code
/opt/openmpi/i386/bin/mpirun -mca btl_openib_verbose 1 --mca btl ^tcp
--mca pls_ssh_agent ssh -mca oob_tcp_peer_retries 1000 --prefix
/usr/lib/openmpi/1.2.8-gcc/bin -np 239 --app procgr
Hi,
I am having trouble using the --app option with OpenMPI's mpirun
command. The MPI processes launched with the --app option get launched
on the linux node that mpirun command is executed on.
The same MPI executable works when specified on the command line using
the -np option.
Please let
