Attention

SCARF is migrating to Rocky 9, please see Rocky 9 Migration for details on the Rocky 9 cluster

SCARF Configuration

The hardware for SCARF is purchased on a yearly basis, with each new addition added to the same set of computational job queues so as to give the users a seamless experience. This has the advantage of meaning that no large outlay of money is needed in a single year, as well as enabling us to get the best quality hardware for our money on each occasion.

The original cluster was a 256 core, 128 node cluster purchased in 2004, which has since been retired from service and completely replaced with the incremental expansions listed below.

Current Hardware Configuration

The SCARF computational cluster is comprised of a number of host groups which are listed in the table below (Scroll to see all of table).
