Hi.... I have a large program written in FORTRAN 77 with a couple of routines written in C++. It has MPI commands built into it to run on a large scale multiprocessor IBM systems. I am now having the task of transferring this program over to a cluster system. Both the multiprocessor and cluster system has linux hosted on them. The Cluster system has GNU FORTRAN and GNU C compilers on it. I am told the Cluster has openmpi. I am wondering if anybody out there has had to do the same task and if so what I can expect from this. Will I be expected to make some big changes, etc.? Any advice will be appreciated.
Thanks.
