Re: [OMPI devel] OMPI performance competitiveness
Hi Eugene, We have licenses of HPMPI, IntelMPI and SpecMPI with us. We usually do comparison tests periodically like recently we did collective performance test on our cluster. I would like to help openmpi community to benchmark their collectives and other calls if given the opportunity. I am using openmpi from last 2 years and have decent understanding of its code-base. I think it would be interesting as well as challenging stuff to make openmpi better then all existing MPI flavours and i would love to work in this direction.

Does anyone have licenses for other MPI implementations (HP, Intel, Platform/Scali, etc.) or individual test suites (SpecMPI, etc.)?

[OMPI devel] selectively bind MPI to one HCA out of available ones
Hi all, I have a cluster where both HCA's of blade are active, but connected to different subnet. Is there an option in MPI to select one HCA out of available one's? I know it can be done by making changes in openmpi code, but i need clean interface like option during mpi launch time to select mthca0 or mthca1? Any help is appreciated. Btw i just checked Mvapich and feature is there inside. Regards Neeraj Chourasia (MTS) Computational Research Laboratories Ltd.
