User manual

This manual is for people using a TrinityX cluster — submitting and monitoring work — rather than administering it. It assumes the cluster has already been set up and that you have an account on it; account creation and cluster configuration are covered in the administration manual.

There are two ways to interact with the cluster, and most users mix them freely:

• the command line, by logging in over SSH to the controller or a dedicated login node, and
• the Open OnDemand portal, a web interface that offers the same everyday tasks — file access, job submission and monitoring — without leaving the browser.

Where to start

• Open OnDemand portal — connecting to the web portal and finding your way around it.
• Job submission — writing a job script and submitting work to the scheduler, from the command line or the portal.
• Job status and overview — checking what your jobs are doing and reviewing what has finished.
• Password change — changing your own password, on the command line or through the portal.

If you are not sure whether your cluster has a separate login node or whether the portal is enabled, ask your cluster administrator — both depend on how your particular TrinityX installation was set up.
