Hi Mike, Stock MPICH2 does not use hwloc directly inside the MPI library. It is only used by the hydra process manager. MVAPICH2 appears to be using hwloc directly inside the library, so you'll need to ask the OSU folks for a fix.
They can be contacted at [email protected]. http://mail.cse.ohio-state.edu/mailman/listinfo/mvapich-discuss -Dave On Sep 10, 2010, at 1:42 PM CDT, Mike Heinz wrote: > Hello all, > > I'm trying to build mvapich2-1.5.1 on an RHEL 5 update 3 system.
