ABSTRACT:
A processor communication register (PCR) contained within a multiprocessor cluster system provides enhanced processor communication. The PCR stores information that is useful in pipelined or parallel multi-processing. Each processor cluster has exclusive rights to store to a sector within the PCR and has continuous access to read its contents. Each processor cluster updates its exclusive sector within the PCR, instantly allowing all of the other processors within the cluster network to see the change within the PCR data, and bypassing the cache subsystem. Efficiency is enhanced within the processor cluster network by providing processor communications to be immediately networked and transferred into all processors without momentarily restricting access to the information or forcing all the processors to be continually contending for the same cache line, and thereby overwhelming the interconnect and memory system with an endless stream of load, store and invalidate commands.
