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: ‐

FILES
The output file has following format:
<hostname> <round-trip-time> <offset-from-hnp>
