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