Abstract

In accordance with some embodiments, spatial and temporal locality between threads executing on graphics processing units may be analyzed and tracked in order to improve performance. In some applications where a large number of threads are executed and those threads use common resources such as common data, affinity tracking may be used to improve performance by reducing the cache miss rate and to more effectively use relatively small-sized caches.
