Memory Trace Compression and Replay for SPMD Systems Using Extended PRSDs

Abstract

Concurrency levels in large-scale supercomputers are rising exponentially, and shared-memory nodes with hundreds of cores and non-uniform memory access latencies are expected within the next decade. However, even current petascale systems with tens of cores per node suffer from memory bottlenecks. As core counts increase, memory issues become critical for… (More)
