EOS, CRAY® XC30™
Decommissioned in August 2019, Eos was a 736-node Cray® XC30™ cluster with a total of 47.104TB of memory. Its processor was the Intel® Xeon® E5-2670. It featured 16 I/O service nodes and 2 external login nodes. Its compute nodes were organized in blades. Each blade contained 4 nodes. Every node had 2 sockets with 8 physical cores each. Intel’s Hyper-Threading (HT) Technology allowed each physical core to work as 2 logical cores so each node could function as if it has 32 cores. In total, the Eos compute partition contained 11,776 traditional processor cores (23,552 logical cores with HT Technology enabled).
