The Mercury Cluster

View of back of Mercury Cluster Illinois Rocstar LLC operates a 256-core compute cluster dedicated to production simulations. The machine, Mercury, is an AMAX Intel Xeon E5530 (64 quad-core) Nehalem-based, 2.4 GHz processor, Linux cluster utilizing QDR InfiniBand interconnect technology. The 32 dual-processor, quad-core 2.4GHz Intel Nahelem-based nodes have 16 GB of RAM each, for a total of 256 cores and 512 GB of RAM. The cluster head-node has dual quad-core 2.66 GHz Nahelem processors and 32 GB of RAM, with 4TB of hard disk in a RAID 5 configuration. Communications are facilitated by both a Gb ethernet management fabric and a Quad-data rate (QDR) Infiniband high speed interconnect. The cluster is protected by online UPS units and has 20 TB of online network accessible storage available.

Illinois Rocstar LLC also owns and operates a group of high-performance engineering workstation-class computers for daily operations. A dual-processor, quad-core (8 total cores), 32 GB RAM machine is configured with dual-NVIDIA Fermi-class GPU cards for use in high-performance simulation GPU research. Each engineer has access to their own quad-core, 8 to 16 GB RAM, dual-monitor Linux-based engineering workstation. Several server-class machines and an additional 15 TB network accessible storage unit are also configured for daily computational use. Computational resources used solely by Illinois Rocstar LLC are located at our business address in the University of Illinois Research Park.

Additional computational resources are available through the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. Illinois Rocstar is a formal NCSA Private Sector Program Partner and has full access to their world-class computational resources. NCSA has recently installed Blue Waters, one of the most powerful supercomputers in the world. It includes more than 400,000 cores and has a peak performance of over 10 petaflops (10 quadrillion calculations per second) and achieves sustained performance of 1 petaflop running a range of science and engineering codes.
