When completed, Stampede will comprise several thousand Dell “Zeus” servers with each server having dual 8-core processors from the forthcoming Intel® Xeon® Processor E5 Family (formerly codenamed “Sandy Bridge-EP”) and each server with 32 gigabytes of memory. This production system will offer almost 2 petaflops of peak performance, which is double the current top system in XD, and the real performance of scientific applications will see an even greater performance boost due to the newer processor and interconnect technologies. The cluster will also include a new innovative capability: Intel® Many Integrated Core (MIC) co-processors codenamed “Knights Corner,” providing an additional 8 petaflops of performance. Intel MIC co-processors are designed to process highly parallel workloads and provide the benefits of using the most popular x86 instruction set. This will greatly simplify the task of porting and optimizing applications on Stampede to utilize the performance of both the Intel Xeon processors and Intel MIC co-processors.
