Hi, Lenny,

So rank file map will be supported in OpenMPI 1.3? I'm using OpenMPI1.2.6 and did not find parameter "rmaps_rank_file_".
Do you have idea when OpenMPI 1.3 will be available? OpenMPI 1.3 has quite a few features I'm looking for.

Re: [OMPI users] Working with a CellBlade cluster


If I understand you correctly the most suitable way to do it is by paffinity that we have in Open MPI 1.3 and the trank.
how ever usually OS is distributing processes evenly between sockets by it self.

There still no formal FAQ due to a multiple reasons but you can read how to use it in the attached scratch ( there were few name changings of the params, so check with ompi_info )

shared memory is used between processes that share same machine, and openib is used between different machines ( hostnames ), no special mca params are needed.

Best Regards
