Hi, I'm bit confused now. When I supply ompi_info, it gives: *[user@localhost openmpi-x86_64]$ ompi_info * *[localhost.localdomain:11068] Error: Unable to get the current working directory* * Package: Open MPI root@3fecdf07461e Distribution* * Open MPI: 2.1.1* * Open MPI repo revision: v2.1.0-100-ga2fdb5b* * Open MPI release date: May 10, 2017* * Open RTE: 2.1.1* * Open RTE repo revision: v2.1.0-100-ga2fdb5b* * Open RTE release date: May 10, 2017* * OPAL: 2.1.1* * OPAL repo revision: v2.1.0-100-ga2fdb5b* * OPAL release date: May 10, 2017* * MPI API: 3.1.0* * Ident string: 2.1.1* * Prefix: /home/user/EMAN2* * Configured architecture: x86_64-unknown-linux-gnu*
Form the Bold line, I assume it is sourcing this version and loading 2.1.1 by default. But when I provide:* rpm -qf /usr/lib64/openmpi/lib/openmpi/mca_shmem_mmap.so* It gives me: *openmpi-1.10.0-10.el7.x86_64* So, I think I'm having some sort of path issue. Is that right ? The program I wish to run will go fine with MCA 2.0.
