Abstract: Apparatus, computer readable medium, and method of servicing memory requests are presented. A read request for a memory block from a requester processing having a processor type may be serviced by providing exclusive access to the requested memory block to the requester processor when the requested memory block was modified a last time it was accessed by a previous requester processor having a same processor type as the processor type of the requester processor. Exclusive access to the requested memory block may be provided to the requester processor based on whether the requested memory block was modified by a previous processor having a same type as the requester processor at least once in the last several times the memory block was in a cache of the previous processor. Exclusive access to the requested memory block may be provided to the requester processor based on a region of the memory block.

Abstract: The described embodiments comprise a first hardware context. The first hardware context receives, from a second hardware context, an indication of a memory location and a condition to be met by the memory location. The first hardware context then sends a signal to the second hardware context when the memory location meets the condition.

Abstract: In some embodiments, a method for improving reliability in a processor is provided. The method can include replicating input data for first and second lanes of a processor, the first and second lanes being located in a same cluster of the processor and the first and second lanes each generating a respective value associated with an instruction to be executed in the respective lane, and responsive to a determination that the generated values do not match, providing an indication that the generated values do not match.
