- # 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.
