mpiprofile
11-175
Option Description
additionally records information about built-in
functions such as eig or labReceive.
-messagedetail default
-messagedetail simplified
This option specifies the detail at which
communication information is stored.
-messagedetail default collects
information on a per-lab instance.
-messagedetail simplified turns off
collection for *PerLab data fields, which
reduces the profiling overhead. If you have
a very large cluster, you might want to use
this option; however, you will not get all the
detailed inter-lab communication plots in the
viewer.
For information about the structure of
returned data, see mpiprofile info below.
-history
-nohistory
-historysize <size>
mpiprofile supports these options in the
same way as the standard profile.
No other profile options are supported by
mpiprofile. These three options have no
effect on the data displayed by mpiprofile
viewer.
mpiprofile off stops the parallel profiler. To reset the state of the profiler and disable
collecting communication information, you should also call mpiprofile reset.
mpiprofile resume restarts the profiler without clearing previously recorded function
statistics. This works only in pmode or in the same MATLAB worker session.
mpiprofile clear clears the profile information.
mpiprofile status returns a valid status when it runs on the worker.
mpiprofile reset turns off the parallel profiler and resets the data collection back to
the standard profiler. If you do not call reset, subsequent profile commands will collect
MPI information.
