Abstract

Composing a representative multi-program multi-core workload is non-trivial. A multi-core processor can execute multiple independent programs concurrently, and hence, any program mix can form a potential multi-program workload. Given the very large number of possible multi-program workloads and the limited speed of current simulation methods, it is impossible to evaluate all possible multi-program workloads.
