Data processing system having novel interconnect for supporting both technical and commercial workloads

摘要

A processor book designed to support both commercial workloads and technical workloads based on a dynamic or static mechanism of reconfiguring the external wiring interconnect. The processor book is configured as a building block for commercial workload processing systems with external connector buses (ECBs). The processor book is also provided with routing logic to enable to ECBs to be utilized for either book-to-book routing or routing within the same processor book. A table specific wiring scheme is provided for coupling the ECBs running off the chips of one MCM to the chips of the second MCM on the processor book so that the chips of the first MCM are connected directly to the chips of a second MCM that is logically furthest away and vice versa. Once the wiring of the ECBs are completed according to the wiring scheme, the operational and functional characteristics reflect those of a processor book configured for technical workloads.
