pl-mpi-dtime(1) OpenBSD Reference Manual pl-mpi-dtime(1) NAME pl-mpi-dtime - pl-mpi run-time trace profiler SYNOPSIS pl-mpi-dtime [-b] [-i interval] file ... DESCRIPTION THe pl-mpi-dtime utility processes files produced by pl-mpi(1) or pl-mpi-test(1) with the -t switch. It produces detailed metrics on the operation of the underlying system during processing. The options are as follows: -b Show the per-index breakdown. The pl-mpi-dtime utility dis- plays both median and mean, but this will force display of each index's statistics in addition. -i interval If interval is 0 (the default), statistics will be gathered and displayed once, and the system will exit. If greater than 0, the utility will poll at the requested interval (in seconds) and update a display like top(1), showing only the most recent results if terminal rows are exhausted. The pl-mpi-dtime utility accepts as arguments trace files generated by pl-mpi(1) and pl-mpi-test(1), which are in the format of dump-rank.txt, where ``rank'' is the MPI rank of the generating node. AUTHORS The pl-mpi-dtime utility was developed at the University of Latvia's IMCS by Kristaps Dzonsons <kristaps.dzonsons@latnet.lv>. BUGS Breakdown mode (with the -b switch) doesn't display properly in polling mode. The system also cannot check whether trace files are from differ- ent run-times.
