## 12.2. Running a Batch Job

A batch job contains a sequence of commands to be executed by the operating system, and is submitted for execution as a single unit. Batch jobs are ideal when you want to run longer processes, or when you are not available to provide input. Once a batch job has been submitted it can run to completion without any intervention from you. The commands are submitted from the EKM server to a cluster via Remote Solve Manager (RSM). A queuing system on the cluster submit host queues the job, allocates processors, and starts and manages the job.

You can start a batch job by launching the default Batch job application on the Applications panel, or by executing a batch job template that has been created in the repository. You can also start a batch job directly from selected simulation files that reside in the EKM repository, or from within the working directory of another job or any folder in the EKM server file system. When you start a batch job you are prompted to accept or specify the job name and then upload files to the working directory. You can upload files from your local computer, the EKM repository, or from another location on the EKM server. Once you have uploaded all necessary files to the working directory, the job will execute automatically by default, and you can monitor its progress on the Job Monitor page.

The Applications panel also contains batch job templates that are specific to certain products (CFX, Fluent, Electronics Desktop, LS-DYNA, MAPDL, Workbench). For more information, see Starting Jobs in EKM.

Note:

- By default, when you submit a batch job, the credentials that you use to sign in to EKM will be used to submit the job to RSM. If you use different credentials to launch RSM services or access a cluster, then you must specify credentials overrides in your EKM settings. See Specifying Job Management Preferences.

- If RSM is running on Windows, the `rsmWindowsDomain` setting must be correctly defined in the ekm.xml file. EKM will prepend the Windows domain name to your `username` when you submit a batch job to RSM.

  For information about defining the `rsmWindowsDomain` setting, see Specifying Remote Process Policies (<remoteProcess>) in the Administration Guide.
