Because of permission reason (OpenMPI can not write temporary file to the default /tmp directory), I change the TMPDIR to my local directory (export TMPDIR=/home/user/tmp ) and then the MPI program can run. But the CPU utilization is very low under 20% (8 MPI rank running in Intel Xeon 8-core CPU).
And I also got some message when I run with OpenMPI: [cn3:28072] 9 more processes have sent help message help-opal-shmem-mmap.txt / mmap on nfs [cn3:28072] Set MCA parameter "orte_base_help_aggregate" to 0 to see all help / error messages Any idea? Thanks VIncent
