Abstract
A computer-implemented method for cache memory management includes receiving a coherence request message from a requesting processor. The method can further include determining a request type responsive to detecting the transactional conflict. The request type is indicative of whether the coherence request is a prefetch request. The method further includes detecting, with a conflict detecting engine, a transactional conflict with the coherence request message. The method further includes sending, with the adaptive prefetch throttling engine, a negative acknowledgement to the requesting processor responsive to a determination that the coherence request is a prefetch request.
