I'm sure it's well explained on openmpi page. Anyway, your OpenMPI eb file should include --with-verbs in configopts and the host you build it on should have ibverbs headers installed. Only tinkering required is to point it to the proper "optimized" ibverbs library, that is possibly specific to the installed infiniband hardware, if that library is somewhere else than standrad locations. -- Jurij Pečar HPC Engineer, IT Operations, IT Services EMBL Heidelberg, Meyerhofstraße 1, 69117, Heidelberg, Germany Room 13-401
