ACC and the Exacloud Cluster

Exacloud is a unique computational resource that was developed collaboratively with an Oregon corporate partner Intel. The goal of this resource was to provide unique capabilities to OHSU researchers for supporting large-scale, computational and data intensive workflows.

The primary Exacloud cluster includes over 6,400 Xeon cores with 86 TB of memory distributed across 172 compute nodes. This computational resource has 26 dedicated, large-memory GPU nodes with 112 advanced GPU's.  There are an additional 16 GPU's in 4 condo (lab-owned) GPU nodes, as well.  The Exacloud architecture includes a Lustre parallel file system, currently with 1.8 Petabytes of usable storage, which can provide users of the cluster with high-speed data access even when cluster utilization is high.  Internally, the cluster uses a combination of 100 Gb/s Infiniband and 1 Gb/s copper Ethernet to interconnect the compute nodes with each other and with the Lustre storage system.

Adjacent to Exacloud is an OpenStack virtualization environment, currently comprised of 10 dedicated hypervisor nodes.  An additional special purpose cluster was developed from the Exacloud Cluster in order to support clinical genomic workflows for the Knight Cancer Institute.

These clusters are housed at OHSU’s state-of-the-art Data Center (DCW) at our West Campus.
