Memory bandwidth: 1991-2009
The Stream benchmark is a measure of sustained memory bandwidth; the target systems are high performance computers. Sustained in the sense of distance running, rather than a short sprint (the term for this is peak memory bandwidth and occurs when the requested data is in cache), and bandwidth in the sense of bytes of memory […]

Techniques used for analyzing basic performance measurements
The statistical design and analysis of experiments is a relatively recent invention (around 150 years old; verifying scientific hypotheses using experiments was first proposed over 1,000 years ago). Once an experiment has been run, and performance measurements collected, what techniques are available to analyse the data? Before electronic computers were invented, the practical statistical techniques […]
