How to set up MARS license server on Linux (e.g. HPC clusters).

[ES3]

On HPC clusters (Quest@NU, CCI@RPI, VS3@BOKU, etc), a program called MARS license daemon (marsld) needs to be started. It can either run on a dedicated license server or on the front node of the cluster, as long as it can communicate with the computing nodes.

MARS version > 2015.1.56

1. Our user provides the MAC address of the license server, ES3 will provide the license daemon executable (e.g. marsld). The license daemon prints license information and exits if it runs with option -I.
2. Add
   

   Code: Select all

   export MARS_LICENSE_SERVER=21630@[server_name]


   
   to bash profile (e.g. ~/.bash_profile). Notice: replace [server_name] with IP address or hostname.
3. Run

   Code: Select all

   source ~/.bash_profile

   to update MARS_LICENSE_SERVER.
4. Start MARS license daemon (marsld) by running

   Code: Select all

   ./marsld

   Note: if permission denied, run "chmod 755 marsld".
5. Run

   Code: Select all

   ps aux |grep marsld

   to check if marsld is started successfully.

MARS version <= 2015.1.56

1. Download MARS license daemon (marsld) from http://mars.es3inc.com/protected/MARS/.
2. Add
   

   Code: Select all

   export MARS_LICENSE_PATH=[license_file_path]
export MARS_LICENSE_SERVER=21630@[server_name]


   
   to bash profile (e.g. ~/.bash_profile). Notice: replace [license_file_path] with the absolute path of the license file received from ES3, replace [server_name] with IP address or hostname.
3. Run

   Code: Select all

   source ~/.bash_profile

   to update MARS_LICENSE_PATH and MARS_LICENSE_SERVER.
4. Start MARS license daemon (marsld) by running

   Code: Select all

   ./marsld

   Note: if permission denied, run "chmod 755 marsld".
5. Run

   Code: Select all

   ps aux |grep marsld

   to check if marsld is started successfully.
