REGULATING ATOMIC MEMORY OPERATIONS TO PREVENT DENIAL OF SERVICE ATTACK

In one embodiment, the present invention includes a method for identifying a termination sequence for an atomic memory operation executed by a first thread, associating a timer with the first thread, and preventing the first thread from execution of a memory cluster operation after completion of the atomic memory operation until a prevention window has passed. This method may be executed by regulation logic associated with a memory execution unit of a processor, in some embodiments. Other embodiments are described and claimed.
