 #  This file describes the mapping of the multi-threaded "raycast" application 
 #  on a multi-clusters, multi-processors architecture.
-#  The mapping of tasks on processors is the following:
-#    - one "main" task on (0,0,0)
-#    - one "render" task per processor but (0,0,0)
+#  The mapping of threads on processors is the following:
+#    - one "main" thread on (0,0,0)
+#    - one "render" thread per processor but (0,0,0)
 #  The mapping of virtual segments is the following:
 #    - There is one shared data vseg in cluster[0][0]
