When using the Unity Cluster service you may want to look at automating your processes. A login service has been created to handle automatic requests and procedures. This server provides the ability to use the at and cron commands with Unity.
The unity-autobot server should be used for automation that you want to occur at a specific time. Examples include downloading a daily dataset, or scheduling a job on the cluster to happen daily or weekly.
The autobot system is not meant for heavy computation and is very limited on CPU/memory. It is not meant to replace the cluster job scheduler for automation. To connect to autobot system in order to set up your at or cron job:
$ ssh name.#@unity-autobot.asc.ohio-state.edu
