SAS partners with the Office of Advanced Research Computing (OARC) to provide HPC resources.  The Amarel HPC cluster operates under a condo model where compute servers can be purchased and will leverage the existing networking and storage infrastructure maintained by OARC.  Membership in this condo cluster is much cheaper than maintaining your own system and provides access to free cycles that aren't being used by other condo participants as well as access to the support personnel and staff scientists in OARC.
