I wonder how MPI maps b/w process and computer nodes. For example, I run 10 processes on 3 computers (pc1,pc2,pc3). Is that right if pc1 will have processes with rank=0,3,6,9; pc2 with rank=1,4,7 and pc3 with rank=2,5,8?
For every run, will MPI run with the same mapping?
Could we statically map b/w processes and computer nodes so that I might be easy for us to know which processs are running on which computer node regardless number of runs?
Thank you for your time and consideration.
