Abstract

High Performance Computing (HPC) environments, by definition, require that systems deliver optimal performance. Given the central role that system memory plays in server performance, deploying high-performance, high- density system memory can improve overall system performance, and ultimately, improve the return on investment (ROI) for HPC systems.

Netlist, Inc. commissioned Tolly to benchmark HPC systems outfitted first with standard registered dual in-line memory modules (RDIMM) and then with Netlist HyperCloud Virtual Dual-Rank RDIMMs. Testing was centered on the industry-standard Standard Performance Evaluation Corp. (SPEC) CPU2006 benchmark suite, the most current available. SPEC CPU2006 benchmark profiles were run in various combinations of 8GB and 16GB RDIMMs running, at 800, 1066 and 1333 MT/s in 2 DIMMs per channel (2DPC) and 3DPC configurations on a SuperMicro server.
