A future version of Open MPI may include support for compiler-specific / non-portable C types. For example, the Intel compiler has specific options for creating a C type that is the same as REAL*16, but we did not have time to include this support in Open MPI v1.3.0.

Mar 14, 2018 · Well, I just downloaded and built Torque master (which is somewhere on the 6.1 path), and then built OMPI master by simply pointing --with-tm=DIR where DIR is the install location I used for Torque. OMPI correctly picked up the Torque support and built all tm components. I can't try executing it, of course, but things seem to build just fine.

(6 replies) The OpenMPI package that ships with CentOS 5.1 does not seem to be compiled with torque support. It does, however, seem to be compiled with gridengine and slurm support. Would it be possible to get this changed?

The OpenMPI project mentions Torque integration in its FAQs on building and running OpenMPI. Similarly, Torque doesn't actually restrict access to CPUs unless cpuset support is enabled. Again, this seems absent in most distro packages. This is why your OpenMPI app, when compiled without Torque integration, can hit all the cores without restriction.

I've tested multiple CPUs with multiple nodes (2x2) and am able to run MPI jobs just fine. However, the RHEL/CentOS version of openmpi is built without torque support. This means that you have to setup your hostsfile and specify the `-np` option to mpirun in order to use OpenMPI in a run and make it work.

The current versions of Slurm and Open MPI support task launch using the srun command. It relies upon Slurm managing reservations of communication ports for use by the Open MPI version 1.5. If OpenMPI is configured with --with-pmi either pmi or pmi2, the OMPI jobs can be launched directly using the srun command. This is the preferred mode of ...

Nov 30, 2012 · However, apparently OpenMPI (where the suffix comes from) auto-detects whether OFED support is available or not, and since we don't explicitly disable OFED/openib support, the suffix is very confusing because you may end up with an OpenMPI that does have OFED support, i.e., what @besserox reports. So, we should do the following:
