HPC Resources

The YCRC maintains and supports a number of high performance computing systems for the Yale research community. Our high performance computing systems are named after notable members of the Yale community.

Each YCRC cluster undergoes regular scheduled maintenance twice a year, see our maintenance schedule for more details.

For proposals, we provide a description of our facilities, equipment, and other resources for HPC and research computing.


We maintain and support three Red Hat Linux compute clusters, listed below. Please click on cluster names for more information.


The Farnam and Ruddle clusters were both retired in 2023 and their users are now supported on the McCleary cluster.

Cluster Name Approx. Core Count Approx. Node Count Login Address Purpose
Grace 26,000 740 general and highly parallel, tightly coupled (InfiniBand)
McCleary 13,000 340 medical and life science, YCGA
Milgram 2,400 80 HIPAA and other sensitive data
Misha 2176 40 Wu Tsai Institute


We maintain several high performance storage systems. Listed below are these shared filesystems and the clusters where they are available. We distinguish where clusters store their home directories with an asterisk. The directory /home will always point to your home directory on the cluster you logged into. For more information about storage quotas and purchasing storage see the Cluster Storage page.
