Logging send/receive events evaluates the rank local within the active communicator, and matches events only if they take place in the same communicator (in other words, it is the same behavior as in MPI).
This User and Reference Guide provides you with the description of the features of the Intel® Trace Collector. This information is provided in the two main sections:
