Systems and methods for efficiently processing data in a non-uniform memory access (NUMA) computing system are disclosed. A computing system includes multiple nodes connected in a NUMA configuration. Each node includes a processing unit which includes one or more processors. A processor in a processing unit executes an instruction that identifies an address corresponding to a data location. The processor determines whether a memory device stores data corresponding to the address. A response is returned to the processor. The response indicates whether the memory device stores data corresponding to the address. The processor completes processing of the instruction without retrieving the data.
