Abstract

Methods and arrangements to assign locks to threads are discussed. Embodiments include transformations, code, state machines or other logic to assign locks to threads. Embodiments may include setting a window of time at the end of a time slice of a thread. The embodiment may also involve prohibiting the thread from acquiring a lock during the window of time, based upon determining that the thread is within the window of time and determining that the thread does not hold any locks. Other embodiments include an apparatus to assign locks to threads and a computer program product to assign locks to threads.
