摘要： A method of operating a central cache controller (“CCC”) in a first cell of a multiprocessor system comprising multiple cells each including globally shared memory (“GSM”), wherein the first cell is disposed in a first partition and the CCC is connected to a plurality of CPUs of the first cell. In one embodiment, the method comprises, responsive to a new transaction request from one of the CPUs, logging the transaction in a transaction table; determining whether an identity marker in a timeout map corresponding to a cell to which the transaction was issued is set; and, responsive to the corresponding identity marker in the timeout map being set, immediately returning a special error to the one of the CPUs that requested the transaction.
