If you consider MPI rank ID as process identifier, clog2 file or slog2
generated from clog2 may be what you are looking for.  If you have
difficulty in understand clog2 format, you may want to read the clog2
READ API's java source code. You can find the code in the directory:

mpe2/src/slog2sdk/src/logformat/clog2

Reading the self-contained java code is the simplest/easiest way to
understand clog2 format. clog2print is compiled from Print.java.
