Abstract
A measurement-based approach for characterizing concurrency present in a workload is developed, and the effect of this concurrency on system performance indices such as cache miss rate and bus activity is quantified. Hardware and software instrumentation of an Alliant FX/8 was used to obtain data from a real workload environment. Results show that 35% of the workload is concurrent, with the concurrent periods typically using all available processors. Probability of a cache miss is seen to increase with concurrency. Regression models are developed to quantify the relationships between cache miss rate, bus activity, and the concurrency measures.
