The Sapelo2 Cluster

The cluster currently has more than 12,300 cores, spanning general-purpose compute nodes (128GB, 192GB RAM), high-memory nodes (256GB, 512GB & 1TB RAM), CPU/GPU hybrid nodes (nvidia K20X, K40 & P100 GPUs). Additionally, the cluster hosts an ever-growing number of researcher-owned compute nodes obtained through the GACRC Buy-In Program. For more information, please see the GACRC wiki.

High-Performance Storage

Data storage for the GACRC-supported cluster is currently provided by a number of storage environments. Notably, the following devices provide $HOME, $SCRATCH, $WORK and $PROJECT capabilities for the GACRC cluster.
