DESCRIPTION

This command is encapsulated in a CMPITclPackagedCommand. It only actually does something if the process has a histogrammer, and that's currently only MPI_EVENT_SINK_RANK In all other processes, this command is a no-op that does not set the result and returns TCL_OK as its status. Thus in the -get, since the non empty MPI_EVENT_SINK_RANK result will be the longest, it will be the command result, which is correct.
