Additionally, users can cancel their jobs using this tool. To view currently running jobs, first select the **Active Jobs** tool, this will bring you to the interface pictured below.

 Although interactive jobs can be extremely helpful, it is often the case that a user would rather submit their job to a cluster where it can run whenever the resources are available. This is accomplished through [Batch Jobs and Job Scripting](../running-jobs/batch-jobs.md). To provide a simple interface for creating batch jobs and jobs scripting, we include the **Job Composer** tool. This tool allows users to modify and create job scripts, schedule jobs, and manage these jobs all in one central location. To create a job, navigate to the **Job Composer** tool and select **New Job**. When first getting started, it is easiest to select **From Default Template**, which will construct a template job with a default name and submit script (job script). Once a new job has been selected, a user can modify the job to their liking by navigating the provided interface. Below we provide a graphic that highlights some of the key features users may be interested in.

+* Job Options : Click to modify a job's name, account, or cluster
+* Submit : Click to submit the selected batch job(s)
+* Stop : Click to cancel the selected batch job(s)
+* Delete : Click to delete batch job script and its containing directory

+Script location:

+Script name:

 Be sure to select the appropriate cluster when creating a job. Additionally, caution should be taken when selecting the delete button. The delete button will remove the entire directory created for the job. In the example provided above, this means that `/projects/breyes@xsede.org/ondemand/projects/default/1` would be completely deleted.

 This will run an interactive job to the Slurm queue that will start a terminal session that will run on one core of one node on the `acpu` partition for ten minutes. Once the session has started you can run any application or script you may need from the command line.  For example, if you load the Python module using `module load python` and then type `python`, you will open an interactive python shell on a compute node (rather than the login nodes, which is forbidden). When you are finished with your interactive job, you can end the session by typing `exit`. If you do not end your session, the interactive job will run for the full time requested, which will use up part of your allocation.
