Hi there!
I have a cluster with 1 compute node rocks 5.4.3.
I want to run a program that located in /opt/mpi-tests/bin with mpirun. when i type the command:
"
mpirun -np 2 -machinefile machines /opt/mpi-tests/bin/ring
"
i receive the error:
"
mpirun was unable to launch the specified application as it could not access or execute an executable:/opt/mpi-tests/bin/ring
node: compute-0-2
"
however when i run the mpi-ring that is a sample on the cluster, in the same way, there isn't any error.

please help me. i'm in a deadline.
