That is simpler. It works on OMPI 1.4.3 too: cat >/usr/common/bin/dumpev.sh <<EOD #!/bin/bash set EOD mpirun -np 4 --host monkey01 --mca plm_rsh_agent rsh /usr/common/bin/dumpenv.sh | grep LOCAL_RANK OMPI_COMM_WORLD_LOCAL_RANK=0 OMPI_COMM_WORLD_LOCAL_RANK=1 OMPI_COMM_WORLD_LOCAL_RANK=2 OMPI_COMM_WORLD_LOCAL_RANK=3 Thanks, David Mathog mat...@caltech.edu Manager, Sequence Analysis Facility, Biology Division, Caltech
