We recently installed Monolix, a model based drug development computing package by Lixoft.

Intallation of a floating cluster license was required to support multiple users making use of the software simultaneously.

Procedure to install a floating license:

Start an X session
Install Monlix and at the end of the install process cancel all license request windows. The software should be installed in <base>/Lixoft/

Download and install the license management server to a server with the same common network software folder into <base>/Lixoft/tools/rlm

Make all relevant files executable.

Edit rlmd.sh

rlmuser=root
rlmdir=<base>/Lixoft/tools
rlmlic=<base>/Lixoft/MonolixSuite2016R1/config/system/access/activate.lic

Run rlm (in the foreground for now)

In a browser open “license.server.ip”:5054 and start the license application

Enter activate.lixoft.net
Enter lixoft
Enter key: xxxx-xxxx-xxxx-xxxx

Enter number of licenses, we choose 18 as we have 18 nodes.

The license folder <base>/Lixoft/tools/rlm
and then copy activate.lic to <base>/Lixoft/MonolixSuite2016R1/config/system/access

Now restart the rlm server, this time as a background daemon and leave it running forever.

Make sure that all relevant files in <base>/Lixoft/MonolixSuite2016R1/bin are set executable.

Login to the cluster as a normal user, export a display and run monolix.sh
