With the introduction of an mpi benchmark (thanks Peter), I would like to start a thread on this which would help me and perhaps others. Some questions: 1) Has anyone tested Intel's mpi to see how much better (if at all) it is? 2) Is there much difference between mpich-1 and mpich-2? 3) Is there much effect for 1) and 2) with ethernet versus myrinet or infiniband? 4) Should one use rsh/ssh or something different for multiple CPU's on one computer?
