I have a CFD software(not written by myself), this code can be run parallel using MPI. On compiled it, I try to run it, and I found that on 2 CPUs, it can run properlly, but on more than 3 CPUs, the program will stopped, no errors were reported, there is no restrictions on use of PC cluster, Can anyone help me on this???
