one more thing, can you run rpm -qf /usr/lib64/openmpi/lib/openmpi/mca_shmem_mmap.so and make sure this comes from the openmpi rpm ?
if not, you can remove the openmpi rpm, rm -rf /usr/lib64/openmpi/lib/openmpi and then re-install the rpm Cheers, Gilles On Fri, Oct 13, 2017 at 10:49 PM, Gilles Gouaillardet <gilles.gouaillar...@gmail.com> wrote: > can you run ldd on your binary ? > i suspect it might not use the right Open MPI library > > Cheers, > > Gilles > > On Fri, Oct 13, 2017 at 10:41 PM, abhisek Mondal <abhisek.m...@gmail.com> > wrote: >> Hello, >> >> I'm getting this following error: >> [localhost.localdomain:00307] mca_base_component_repository_open: shmem >> "/usr/lib64/openmpi/lib/openmpi/mca_shmem_mmap" uses an MCA interface that >> is not recognized (component MCA v2.0.0 != supported MCA v2.1.0) -- ignored >> [localhost.localdomain:00307] mca_base_component_repository_open: unable to >> open mca_shmem_posix: /usr/lib64/openmpi/lib/openmpi/mca_shmem_posix.so: >> undefined symbol: opal_shmem_base_output (ignored) >> [localhost.localdomain:00307] mca_base_component_repository_open: shmem >> "/usr/lib64/openmpi/lib/openmpi/mca_shmem_sysv" uses an MCA interface that >> is not recognized (component MCA v2.0.0 != supported MCA v2.1.0) -- ignored >> >> I had installed it using yum command: yum install openmpi-1.10.0-10.el7 >> >> My current MCA version is showing 2.1.0. >> >> On Fri, Oct 13, 2017 at 1:24 PM, Gilles Gouaillardet >> <gilles.gouaillar...@gmail.com> wrote: >>> >>> Hi, >>> >>> let's take one or two steps back. >>> >>> which version of Open MPI did you use in order to build your program ? >>> >>> what does "not working under MCA2.1" mean ? >>> link error ? unresolved symbols ? runtime crash ? >>> >>> please detail your environment and post all relevant error messages >>> >>> Cheers, >>> >>> Gilles >>> >>> On Fri, Oct 13, 2017 at 10:17 PM, abhisek Mondal <abhisek.m...@gmail.com> >>> wrote: >>> > >>> > Hi, >>> > >>> > I have installed an openmpi using following command: >>> > yum install openmpi-1.10.0-10.el7 >>> > >>> > When I put ompi_info command it shows me that it is using MCAv.2.1.
