ab: Summary: The Scalasca toolset has successfully demonstrated measurement and
    analysis scalability on the largest computer systems, however,
    applications have growing complexity and increasing demands on
    performance tools. One such application is the PFLOTRAN code for
    simulating multiphase subsurface flow and reactive transport. While
    PFLOTRAN itself and Scalasca runtime summarization both scale well, MPI
    communicator management becomes critical for trace collection with tens
    of thousands of processes. Re-design and re-engineering of key
    components of the Scalasca measurement system are presented which
    encompass the representation of communicators, communicator definition
    tracking and unification, and translation of ranks recorded in event
    traces.
