+ * For each task received, the slave executes it and then destroys it. This program declares several tracing categories
+ * that are used to classify tasks. When the program is executed, the tracing mechanism registers the resource
+ * utilization of hosts and links according to these categories. You might want to run this program with the following
+ * parameters:
+ * --cfg=tracing:yes
+ * --cfg=tracing/categorized:yes
+ * --cfg=tracing/uncategorized:yes
+ * --cfg=viva/categorized:viva_cat.plist
