Jeff,
We currently have a set of lam-mpi programs we need to get running and we
haven't spent much time researching OpenMPI. Would our lam-mpi programs be
compatible with OpenMPI? And if so would it make the task of cross-compiling
for the nodes easier? BTW: I'm headint to the openMPI website right now.
