3 # Simple timing test for the MPI library. Basically, we use prime
4 # generation as a timing test, since it exercises most of the pathways
5 # of the library fairly heavily. The 'primegen' tool outputs a line
6 # summarizing timing results. We gather these and process them for
7 # statistical information, which is collected into a file.
