Abstract
An apparatus is described comprising a cluster of processing elements. The cluster having a split mode in which the processing elements are configured to process independent processing workloads, and a lock mode in which the processing elements comprise at least one primary processing element and at least one redundant processing element, each redundant processing element configured to perform a redundant processing workload for checking correctness of a primary processing workload performed by the primary processing element. Each processing element has an associated local memory comprising a plurality of memory locations. A local memory access control mechanism is configured, during the lock mode, to allow the at least one primary processing element to access memory locations within the local memory associated with the at least one redundant processing element.
