4.6.4. Configuring a Remote Simulation

Once you have set up the link between Analyst and your cluster, you can configure a simulation to run on your cluster.

  1. On the Simulation ribbon in the Configuration group, choose Properties to display a properties dialog box. On the Job tab of the dialog box, from the Queue menu, choose the remote host on which you would like to run the simulation from the hosts you configured and enabled (see “Creating the Linux Job Scheduler Remote Host”).

  2. Choose the Maximum Number of Processes (cores) on which you would like your job to run (see “Job Configuration”). Note that the default value for Maximum Number of Processes (0) implies "use all available processes" and permits the fullest utilization of available resources. This may not be what you want, as on some clusters your job may be placed at the end of the queue, waiting for prior jobs requesting less resources to finish.

  3. Choose the Number of Threads Per Process (see “Job Configuration”).

  4. Choose the Number of Remote Nodes on which you would like your job to run (see “Job Configuration”). Note that the default value for Number of Remote Nodes (0) implies "use all available nodes" and permits the fullest utilization of available resources. This may not be what you want, as on some clusters your job may be placed at the end of the queue, waiting for prior jobs requesting less resources to finish.

    Analyst will attempt to apportion the maximum number of processes you choose equally over the number of nodes you choose, up to the maximum number of available nodes and processes on your cluster. If you choose to run one process and accept the default value of zero for Number of Remote Nodes, your job will run as a single process on a single node.

  5. Click OK or press ENTER to close the dialog box.

  6. Assuming your simulation configuration is otherwise complete, you are ready to run the simulation as you normally would.
