I got MPI working on a single machine in client/server mode. How do I scale it to multiple machines? Lets say I have 6 processors on server X, 7 on server Y and a single processor client machine. What would I need to do to set this up?

<br>attach a pvclient to it. To try it out on your single machine (and<br>create a 2-processor server), do the following.<br><br>mpirun -np 2 pvserver<br>pvclient<br><br>- Amy<br><br>Gregory, David C CIV NSWCDD, G24 wrote:
