Abstract
In a multiprocessor system level 2 caches are positioned on the memory side of a routing crossbar rather than on the processor side of the routing crossbar. This configuration permits the processors to store messages directly into each other's caches rather than into system memory or their own coherent caches. Therefore, inter-processor communication latency is reduced.
