I am slightly confused. I guess I had inferred the openmpi issues from the various mailing lists. But I just looked at the latest mpich2 prerelease and found no mentioning of (s)xcpu(2). I thought that some patches/support on the side of the mpi library are necessary (as, e.g., openmpi provides for bproc ...) Or am I completely misunderstanding something here, and this is somehow handled by xcpu itself ... I guess there is some difference between xrx 192.168.19.2 /bin/date and xrx 192.168.19.2 <pathto>/mpiexec ... and the latter seems too magic to me to run out of the box (it sure would be nice though ...)
