HokieSpeed is a 209 node cpu/gpu cluster housed in Virginia Tech's Advanced Research Computing (ARC) facility. The team that designed and deployed HokieSpeed was led by Dr. Wu Feng of the Department of Computer Science. Each system node contains two 2.40-gigahertz Intel Xeon E5645 6-core CPUs, and two NVIDIA 2050 448-core GPUs, for a total of more than 2,500 CPU cores and more than 185,000 GPU cores. The system has an aggregate 4992 GB of memory and is interconnected with quad data rate (QDR) InfiniBand. It made its debut in November 2011 as the 11th ranked system on the Green500 list.
