HCC offers Priority Access on a cost-recovery basis to the HCC user community. Costs recovered include the purchase price plus a University approved $600/year administration fee per server. These resources are in-practice owned by particular research groups. For storage this is implemented as a quota; for computing resources we utilize partitions in the SLURM scheduler. Only specific groups are allowed to submit jobs to a Priority Access partition. When otherwise idle, the broader HCC user community may use Priority Access resources, but the jobs are preempted when the resources are needed by the resource owners.
As of January 2017, HCC offers substantially subsidized pricing on its Priority Access offerings by utilizing NRI funding. HCC subsidizes new purchases by 10% of the already negotiated competitive bid price. This subsidy program also covers the annual administration fee as well as networking and infrastructure costs for the warrantied lifetime of the resource. Annual lease prices are also available that are subsidized by at least 20%. This program is available to all University of Nebraska faculty and staff, and applies to equipment managed by HCC and housed at one of its data centers.
- Subsidies are greater for older or out of warranty systems.
- CraneOPA refers to our most recently purchased machines connected by OmniPath Architecture (OPA). These nodes utilize existing Crane infrastructure such as the login node and the /home and /work filesystems.
- Attic is designed for users who need long-term storage for large amount of data.
- Anvil is HCC's cloud machine; nodes and additional storage may be reserved.
