According to Jeff's comment, OpenMPI compiled with --enable-heterogeneous is broken even in an homogeneous cluster.
as a first step, MTT could be ran with OpenMPI compiled with --enable-heterogenous and running on an homogeneous cluster (ideally on both little and big endian) in order to identify and fix the bug/regression. /* this build is currently disabled in the MTT config of the cisco-community cluster */ Gilles On 2014/04/26 9:41, Ralph Castain wrote: > So it sounds like we may have a test platform, which leaves the question of > repair > > George: can you give us some idea of what was broken and/or pointers on what > needs to be done to repair it? >
