NACS hosts and manages the Middle Performance Computing (MPC) “Beowulf” Cluster on behalf of campus researchers who need substantial computational power.

MPC comprises private nodes and shared nodes, including a part-time shared cluster using NACS PC lab systems. MPC systems feature a mix of architectures to provide high computational throughput.

A feature of the MPC service is the opportunity for researchers to join their own systems to the cluster. In exchange for system administration, housing, and 24/7 oversight provided by NACS, researchers allow 25% of their systems to be configured as part of a campus computational resource. (The remaining 75% is configured to be a cluster, or “queue”, dedicated to the owner.) Contributors may, of course, make use of systems designated for campus use.

Contributors also become voting members of the MPC Advisory Board. The purpose of the MPCAB is to advise NACS on the governance, policies, procedures, and technical aspects of the MPC cluster.

Researchers may request accounts on MPC (and other NACS resources) online. Any future changes that impact MPC users will be posted on the MPC website.

NACS also hosts the GradEA Beowulf Cluster for the exclusive use of UCI graduate students.
