Matlab MCDS

Matlab MCDS

This section will detail any specific customization made during the installation and configuration of the Matlab

MCDS service.

Matlab Installation

The installation followed the steps documented here:-

http://uk.mathworks.com/help/install/ug/install-mathworks-software.html

The default install locations were chosen.

All products that were made available from the Matlab portal were installed.

The supplied key was for "MATLAB Distributed Computing Server"

The software was installed on a vApp comprising of a single VM with 4 vCPUs (2 core), 16Gb memory and

120Gb disk.

Manually starting Matlab DCSE

Starting the FlexNET licence server

Place client license file in default location:

<MATLAB_HOME>/licenses/license.dat

The license file must contain the following two lines:only

SERVER server_name server_MAC 27000

USE_SERVER

Open port for licence server and DCSE, add the following to /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 27000 -j ACCEPT -A INPUT -m

state --state NEW -m tcp -p tcp --dport 27352 -j ACCEPT

Start the license daemon (using erw user)

<MATLAB_HOME>/etc/lmstart -u erw

Note: The licence server cannot be started as

root, it must be started either from a shell

as an unprivileged or using the '-u' switch to 

specify a non-root user If no errors are show when starting the server, confirm the license is available by running:

FlexLM Licence Service

The FlexLM service will have been mostly configured during installation but no startup scripts are provided.

Create the init file

touch /etc/init.d/flexlm

Mark file as executable

chmod a+x /etc/init.d/flexlm

Copy the following into the file:

#!/bin/bash

 

### BEGIN INIT INFO

MDCE Service

You must manually start the MDCE service at least once in order to use the 'admincenter' GUI to configure the

worker nodes. When MDCE has been confiured a service script must be created.

Create the init file

touch /etc/init.d/matlab-mdce

Mark file as executable

chmod a+x /etc/init.d/matlab-mdce

Copy the following into the file:

MATLAB User Settings

The default MATLAB configuration will attempt to use a 'local' 'distcomp' engine. To pre-configure new users to

use the MDCE engine, the following file must be added to /etc/skel

 /etc/skel/.matlab/R2015a/parallel.settings

Add the following to the parallel.settings file:
