.SH "DESCRIPTION"
.PP
The
TAU_PROFILE_SET_NODE
macro sets the node identifier of the executing task for profiling and tracing. Tasks are identified using node, context and thread ids. The profile data files generated will accordingly be named profile.<node>.<context>.<thread>. Note that it is not necessary to call
TAU_PROFILE_SET_NODE
when using the TAU MPI wrapper library.
