MATLAB Distributed Computing Server Licensing Guide

Prepare On-Site Cluster for MathWorks Hosted License Manager
FlexNetRoot/etc/license.dat
(Your license file name and location might vary.)
2 In the file, locate and remove the entry that begins with the text:
INCREMENT MATLAB_Distrib_Comp_Engine ...
The entry might span more than one line in the file. Remove the entire entry and
save the file.
3 Restart FlexNet for the changes to take effect.
FlexNet utilities such as lmstat can verify that only the proper products are licensed.
Step 3a: Modify License Parameters in Definitions File (MJS Only)
The mdce process uses its parameter definitions file to control the behavior of the
MATLAB job scheduler (MJS) and workers. Where matlabroot indicates the folder of
the cluster MATLAB installation, the definitions file is located at:
matlabroot/toolbox/distcomp/bin/mdce_def.sh (UNIX)
matlabroot\toolbox\distcomp\bin\mdce_def.bat (Windows)
• When using MathWorks hosted license manager, modify the mdce_def file to set the
online licensing parameter value to true.
For R2012b or earlier, the line should read as either one of the following:
ONLINE_LICENSE_MANAGEMENT="true" (UNIX)
set ONLINE_LICENSE_MANAGEMENT=true (Windows)
For R2013a or later, the line should read as either one of the following:
USE_MATHWORKS_HOSTED_LICENSE_MANAGER="true" (UNIX)
set USE_MATHWORKS_HOSTED_LICENSE_MANAGER=true (Windows)
The USE_MATHWORKS_HOSTED_LICENSE_MANAGER parameter automatically releases
licenses when workers are idle. By releasing licenses during idle times, other ondemand
workers can use these licenses, as needed.
With the new settings in the mdce_def file, restart the cluster resources (MJS and
workers) in the usual manner as described in the installation and configuration sections
of the MATLAB Distributed Computing Server documentation.
