9 * - <b>tracing/categories.c</b> This is a master/slave program where the master creates tasks, send them to the slaves.
10 * For each task received, the slave executes it and then destroys it. This program declares several tracing categories
11 * that are used to classify tasks. When the program is executed, the tracing mechanism registers the resource
12 * utilization of hosts and links according to these categories. You might want to run this program with the following
15 * --cfg=tracing/categorized:yes
16 * --cfg=tracing/uncategorized:yes
17 * --cfg=viva/categorized:viva_cat.plist
18 * --cfg=viva/uncategorized:viva_uncat.plist
19 * (See \ref tracing_tracing_options for details)
