Sierra User Guide: Technical Summary

Sierra is a dedicated FutureGrid cluster consisting of 84 compute nodes and two storage nodes. Each compute node contains two sockets, each with a 4-core 2.5 GHz Xeon processor, for a total of 8 cores per node and 672 total cores for the system. Each node has 32 GB of DDR2 and is connected via 20-Gbps DDR InfiniBand interconnect. Sierra has a theoretical peak performance of 7 TFlop/s. Sierra has two Sun x4540 storage servers at 48 TB each for a total of 96 TB of raw storage.

• 84 compute nodes
• Two quad-core 2.5 GHz Xeon processors per node (672 compute cores)
• 32GB of DRAM per node (2.6 TB total DRAM)
• Peak performance of 7 teraflops
• InfiniBand DDR interconnect
• ZFS filesystem with 76.8 TB raid2 storage and 5.4 TB of raid0 (for scratch)
