- * - <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:yes
- * --cfg=tracing/uncategorized:yes
- * --cfg=viva/categorized:viva_cat.plist
- * --cfg=viva/uncategorized:viva_uncat.plist
- * (See \ref tracing_tracing_options for details)
