Default On parallel
Posts: n/a
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???

It is difficult to identify which kinds of problem your code have according to your information.
