So far our discussion has been centered on how to build a correct and efficient shared memory multiprocessor, by providing cache coherence, memory consistency, and synchronization primitives. We have assumed that messages are reliably sent from one processor to another with a low latency. However, we have not discussed how messages can be sent reliably and fast from one node to another.

The objective of this chapter is to discuss ...
