mpiSettings
Configure options for MPI communication
Syntax
mpiSettings('DeadlockDetection','on')
mpiSettings('MessageLogging','on')
mpiSettings('MessageLoggingDestination','CommandWindow')
mpiSettings('MessageLoggingDestination','stdout')
mpiSettings('MessageLoggingDestination','File','filename')
Description
mpiSettings('DeadlockDetection','on') turns on deadlock detection during calls
to labSend and labReceive. If deadlock is detected, a call to labReceive might cause
an error. Although it is not necessary to enable deadlock detection on all workers, this
is the most useful option. The default value is 'off' for communicating jobs, and 'on'
inside pmode sessions or spmd statements. Once the setting has been changed within a
pmode session or an spmd statement, the setting stays in effect until either the pmode
session ends or the parallel pool is closed.
mpiSettings('MessageLogging','on') turns on MPI message logging. The default
is 'off'. The default destination is the MATLAB Command Window.
mpiSettings('MessageLoggingDestination','CommandWindow') sends
MPI logging information to the MATLAB Command Window. If the task within a
communicating job is set to capture Command Window output, the MPI logging
information will be present in the task's CommandWindowOutput property.
mpiSettings('MessageLoggingDestination','stdout') sends MPI logging
information to the standard output for the MATLAB process. If you are using a MATLAB
job scheduler (MJS), this is the mdce service log file.
mpiSettings('MessageLoggingDestination','File','filename') sends MPI
logging information to the specified file.
