Yes Tim it's along these lines, I see, so if I understand correctly we have two options:
1-Using a network file system (it will be the file system's responsibility to export P binaries from C to A and B) 2-manually copy the binaries to the machines that will be executing the program P (in this case machine A and machine B) Since in my case I will not use a distributed file system I will have to go for option 2. I will have to write a script that updates machines A and B each time P is modified. So just to clarify, what you mean is that the P binaries HAVE to reside in machines A and B prior to execution of P from machine C? thank you herbey On Mon, Mar 22, 2010 at 11:06 AM, Timothy Hayes <haye...@tcd.ie> wrote: > If I understood your question correctly, it's not really the MPI > implementation's duty to solve this issue.
