Decommission Notice: Eos was decommissioned on August 2, 2019.

Eos is a 736-node Cray® XC30™ cluster with a total of 47.104TB of memory. Its processor is the Intel® Xeon® E5-2670. It features 16 I/O service nodes and 2 external login nodes. Its compute nodes are organized in blades. Each blade contains 4 nodes. Every node has 2 sockets with 8 physical cores each. Intel’s Hyper-Threading (HT) Technology allows each physical core to work as 2 logical cores so each node can function as if it has 32 cores. In total, the Eos compute partition contains 11,776 traditional processor cores (23,552 logical cores with HT Technology enabled).
