Question:

How do I know that the process migration works

Answer:

Run "mosmon" in one screen. Then run several copies of a test (CPU bound) program, e.g.,

mosrun -e awk 'BEGIN {for(i=0;i<100000;i++)for(j=0;j<100000;j++);}'

First you should see an increase of the load in one node. After a few seconds, if the process migration works you will see how the load is spread among the nodes.

If your nodes are not of the same speed then more processes will run in the faster nodes.
