STREAM and the Performance Impact of Compiler Optimization

Fintan Ryan, September 13, 2007

Introduction

A couple of weeks back there was a discussion on the perf-discuss alias over on opensolaris.orgaround memory bandwidth/throughput benchmarks, and as is customary in such a discussion STREAM got a mention.
