.SH DESCRIPTION
|
|
.sp
|
|
\fBmpisync\fP: determines clock offsets relative to Head Node Process
|
|
(HNP). It accepts the following options:
|
|
.INDENT 0.0
|
|
.IP \(bu 2
|
|
\fB\-o\fP, \fB\-\-output\fP: The name of output file where offsets related
|
|
to HNP will be written
|
|
.IP \(bu 2
|
|
\fB\-h\fP, \fB\-\-help\fP: Print help information
|
|
.UNINDENT
|
|
.sp
|
|
\fBompi_timing_post\fP 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 \fBfirst\fP : \fBprevious\fP
|
|
event.
|
|
.sp
|
|
\fBmpirun_prof\fP is a wrapper around \fI\%mpirun\fP that
|
|
performs clock synchronisation and post\-processing of the timing
|
|
output file.
|
|
.SH NOTES
