Abstract
A computer implemented method, apparatus and program product automatically optimizes hash function operation by recognizing when a first hash function results in an unacceptable number of cache misses, and by dynamically trying another hash function to determine which hash function results in the most cache hits. In this manner, hardware optimizes hash function operation in the face of changing loads and associated data flow patterns.
