What is Optimizing Communication in SMP Clusters about?

This document discusses communication optimization strategies for SMP clusters. It describes how communication works within a node using shared memory versus between nodes over a network. Key points of optimization include using threads within a node, shared memory segments, and modifying the communication pattern to reduce inter-node traffic. The document also covers bottlenecks like memory copying, network adapters, switches, and how to optimize collective operations and process mapping.
