mpisync -- Open MPI timing tools

SYNTAX
       mpisync [options]

       mpirun_prof [options]

       ompi_timing_post [<timing-file>] [<processed-file>]

DESCRIPTION
       mpisync: determines clock offsets relative to Head Node Process (HNP).
       It accepts the following options:

       o -o, --output: The name of output file where offsets related to HNP
         will be written

       o -h, --help: Print help information

       ompi_timing_post takes the timing output file as input parameter.  The
       events are sorted by the timestamps. Next, the timestamps are replaced
       with time offsets relative to the first : previous event.

       mpirun_prof is a wrapper around mpirun that performs clock
       synchronisation and post-processing of the timing output file.

NOTES
       The mpisync code was derived from MPIPerf project:
       http://mpiperf.cpct.sibsutis.ru/index.php/Main/Documentation

FILES
       The output file has following format:

          <hostname> <round-trip-time> <offset-from-hnp>
