Claim One:
1. A multiprocessing system comprising: a plurality of processors having a plurality of high-bandwidth point-to-point links; a plurality of processor clusters, each processor cluster having a predefined number of the processors residing therein, each of the high-bandwidth point-to-point links being from one respective processor residing in one of the plurality of processor clusters to another respective processor residing in one of plurality of the processor clusters, each of the processor clusters having a number of link groups equal to the number of processor clusters minus one; and a plurality of crossbars, one of the crossbars coupling each of the processors of one of the plurality of processor clusters to each of the processors of another of the plurality of processor clusters, such that all processors are communicatively coupled to each of the other processors, and such that the number of crossbars is equal to [X*(X−1)/2], wherein X equals the number of processor clusters.
