Resolving The Problem
Why do my jobs using Intel MPI implementation fail to run?
Symptom: Jobs using the Intel MPI implementation failed to run.
Explanation: By default, the Intel MPI uses rsh to communicate between nodes.
Solution: If you did not configure rsh, you need to explicitly pass the --rsh=ssh command to manually use ssh. For example,
# mpdboot --rsh=ssh -n 6 -f mpd.hosts
# mpirun --rsh=ssh -n 6 benchmarks/hpl/bin/GBE-intel-mpi/xhpl
