Abstract:
A method includes performing one or more operations as requested by a thread executing on a processor, the thread having a thread context; receiving a park request from the thread, the park request received following a request from the thread for a low latency resource, wherein the cache response time is less than or equal to a resource response threshold so as to allow the thread context to be stored and retrieved from the cache in less time than the portion of time it takes to complete the request for the low latency resource; storing the thread context in the cache; detecting that the resume condition has occurred; retrieving the thread context from the cache; and resuming execution of the thread.
