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.

摘要:
A method of optimally deploying virtual images in a system of servers having different architectures and resources automatically deploys a first virtual image to each of a plurality of servers in the heterogeneous system of servers. The method monitors performance of the first virtual image on each of the servers. The method calculates a quality of service metric for the first virtual image on each server. The method ranks the servers in terms of said quality of service metric for the first virtual image. The method automatically deploys the first virtual image to a highest ranked server in terms of quality of service metric for the first virtual image.
