Abstract: The present disclosure relates to a method for a computer system comprising a plurality of processor cores, wherein a cached data item is assigned to a first core of the processor cores for exclusively executing an atomic primitive by the first core. The method comprises, while the execution of the atomic primitive is not completed by the first core, receiving from a second core at a cache controller a request for accessing the data item. In response to determining that a second request of the data item is received from a third core, of the plurality of processor cores, before receiving the request of the second core, a rejection message may be returned to the second core.
