STREAM: Analyses and Commentary
This is a new section to gather together a variety of graphs and
comments on the STREAM benchmark results, and on the topic of memory
bandwidth in general.
I have written up my methodology for estimating STREAM Triad bandwidth using
published results from the 171.swim benchmark in SPEC's CPU2000 suite. These
are not publishable STREAM results, but they definitely give a good rough
estimate on a wide variety of systems.
This is a slightly updated version of a presentation that I made at
the TOP500 meeting at SuperComputing2002 in November. The slides
show a methodology for getting reasonably accurate estimates of
SPECfp_rate2000 using only one measurement, plus a set of architectural
parameters of the system.
Papers: (oldies but goodies -- available online again!)
