ACC Cluster Computing

In January 2025, the Exacloud Cluster (a unique computational resource that was developed collaboratively with an Oregon corporate partner Intel) was decommissioned and replaced by the currently available ARC cluster*.

ARC is a high performance computing cluster at OHSU. The goal of this resource is to provide unique capabilities to OHSU researchers for supporting large-scale, computational and data intensive workflows.

The primary ARC cluster includes over 6,400 Xeon cores with over 130 TB of memory distributed across 160 compute nodes. This computational resource includes dedicated, large-memory GPU nodes with advanced GPUs. Internally, the cluster primarily uses a 200 Gb/s Infiniband interconnect between the compute nodes and storage systems. These storage systems include ACC's Fortera and Object platforms.

ACC clusters are housed at OHSU’s state-of-the art West Campus data center (DCW).
