Overview

When logging into hydra you will find yourself on the head node, which is the part of the hydra cluster reserved for interactive use (i.e. tasks such as compilation, job submission and control).

You must apply for an account before logging on. There is no access to the system by default. See the quick links at left for information on applying for an account.

If you have issues with this then let us know. Typical issues are the browser not being able to run the java applet that provides the login, either because the java plugin is not enabled in your browser or you do not have java installed. Refer to Oracle's Java pages for more information.
