- * - <b>tracing/ms.c</b> This is a master/slave program where the master creates
- * tasks, send them to the slaves. For each task received, the slave executes
- * it and then destroys it. This program uses several tracing functions that
- * enable the tracing of categorized resource utilization, the use of trace marks,
- * and user variables associated to the hosts of the platform file.
- * You might want to run this program with the following parameters:
- * --cfg=tracing/categorized:1
- * --cfg=tracing/uncategorized:1
- * --cfg=triva/categorized:triva_cat.plist
- * --cfg=triva/uncategorized:triva_uncat.plist
