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*
* Ope
>From the output you supplied, it looks like you are running Open MPI v2.1.x.
Did you install Open MPI v2.1.x from source, and install it into the same
directory that you had previously installed Open MPI v2.0.x?
If so, the warnings you are seeing (not errors) are likely the fact that there
are
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

Abhisek ... Gilles asked which program you re trying to run, and how it
was linked with OpenMPI
Also please realise that you do not HAVE to use the openmpi packages
provided by your linux distribution.
It is perfectly OK to download, compile and install another version.

can you run ldd on your binary ?
i suspect it might not use the right Open MPI library
Cheers,

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

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

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. Is
there any way I can use MCA2.0 ?
My program is not working under MCA2.1.
Please help me out here.
Thank you.
