I'm afraid I really don't know what problem the Irix MPI_MSGS_PER_PROC is
trying to solve, so let's try going at this from another angle. What
exactly is happening to your program? Is LAM displaying any error
messages? If, so what are they?
Also, some info on your application might not be a bad thing. Such as how
many processes you are running, what the configuration of the machines are
(uni-processor, dual, quad, etc). You mentioned that you have some
asynchronous send/recv operations. How many would you say are outstanding
at any given time?
Thanks,
Brian
