A simple separated layout program
Write a simple MPI program that is able to put a rank to a specific node.Brief requirements:
- discover the layout of physical nodes.
- put a specific rank to a specific node.
- print out the layout info (rank number and its node)
This program should have nothing to do with MILC. The advantage of doing this is that I can learn how to layout a program and isolate the complexity of MILC. After finishing this tiny program, it will be easy to copy this layout code to original MILC.
