Abstract

Method, apparatus, and program means for a programmable event driven yield mechanism that may activate other threads. In one embodiment, an apparatus includes execution resources to execute a plurality of instructions and a monitor to detect a condition indicating a low level of progress. The monitor can disrupt processing of a program by transferring to a handler in response to detecting the condition indicating a low level of progress. In another embodiment, thread switch logic may be coupled to a plurality of event monitors which monitor events within the multithreading execution logic. The thread switch logic switches threads based at least partially on a programmable condition of one or more of the performance monitors.
