Profile parallel communication and execution times
Syntax
mpiprofile
mpiprofile on <options>
mpiprofile off
mpiprofile resume
mpiprofile clear
mpiprofile status
mpiprofile reset
mpiprofile info
mpiprofile viewer
mpiprofile('viewer', <profinfoarray>)
Description
mpiprofile enables or disables the parallel profiler data collection on a MATLAB
worker running a communicating job. mpiprofile aggregates statistics on execution
time and communication times. The statistics are collected in a manner similar to
running the profile command on each MATLAB worker. By default, the parallel
profiling extensions include array fields that collect information on communication with
each of the other workers. This command in general should be executed in pmode or as
part of a task in a communicating job.
mpiprofile on <options> starts the parallel profiler and clears previously recorded
profile statistics.
mpiprofile takes the following options.
Option Description
-detail mmex
-detail builtin
This option specifies the set of functions
for which profiling statistics are gathered.
-detail mmex (the default) records
information about functions, local functions,
and MEX-functions. -detail builtin
