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