# 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.
