Hi Steve,

I am attempting to duplicate the problem that you reported with today's OFED build (on Sles11, if that matters). I have rarely
used openMPI, so suggestions would be helpful. Here is what I see:

elm3b199:/usr/lib # /usr/mpi/gcc/openmpi-1.4.1/bin/mpirun -np 2 --bynode --mca btl_openib_cpc_include rdmacm ring
--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not find an executable:

Executable: ring
Node: elm3b199

while attempting to start process rank 0.
--------------------------------------------------------------------------
elm3b199:/usr/lib #

Incidentally tvflash did not build (this is a ppc64 machine).

Thanks
Pradeep
