The New Cluster

The cluster currently has 8,240 compute cores, spanning general-purpose compute nodes (128GB RAM), high-memory nodes (512GB & 1TB RAM), CPU/GPU hybrid nodes (nvidia K40 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.

Legacy Cluster (zcluster)

The penultimate cluster (named zcluster) deployed by the GACRC over the period 2009-2012 is comprised of an assembly of components sourced through different manufacturers.

The zcluster is comprised of compute nodes with 4, 6, 8, and 12-core processors from both Intel and AMD. Subsets of nodes have "large memory" (e.g., 128, 256, and 512GB of RAM), while others have infiniband connectivity, and GPU capabilities. Total CPU compute power is 25.9 Tflops. 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 and $PROJECT capabilities to both GACRC clusters. 

  • Panasas ActiveStor12 (156TB) -  $HOME and $SCRATCH on zcluster.  
  • Seagate ClusterStor1500 Lustre appliance (480TB) - $SCRATCH on New Cluster.
  • Penguin IceBreakers storage chains running ZFS (100TB) - $HOME on New Cluster.
  • Penguin IceBreakers storage chains running ZFS (560TB) -  $PROJECT research groups' long-term space on both GACRC clusters.
  • Penguin IceBreakers storage chain running ZFS (720TB) -  backup environment for $HOME and $PROJECT.
