| 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. | |
