Services

At the heart of Advanced Research Computing is a range of state of the art high performance computers that all do slightly different things. You may find that the application which you plan to use has already been installed on some of them but not others. Alternatively, you may have a new application but are unsure of the best system to run it on. If in doubt, please contact the ARC staff.

The host name you require for connecting to each facility is shown in the table below. If you are unsure which service to use, please contact the ARC staff.
