+ * - <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)
