Abstract: SAND2011-1446C Concurrency Fundamental assumptions of system software architecture and application design did not anticipate exponential growth in parallelism Courtesy: Al Geist (ORNL) Performance: Single-node (multi-GPUs) • Single workstation with 4 Tesla C1060 cards • 10-50X speed-ups, larger systems -data locality • Super-linear speed-ups for larger systems • Beats 100-200 cores of ORNL Cray XT5 (#1 in Top500) Performance metric (ns/day) Challenge: How do all cores use a single (or limited) GPUs?Solution: Use pipelining strategy* Pipelining: scaling on multi-core/multi-node with GPUs * =
