Parallel Computer Architecture

828 CHAPTER 10 Interconnection Network Design

depends heavily on the cost model associated with the target technology and the

characteristics of the communication pattern in the target workload. Finally, as with

many other aspects of architecture, there is significant room for debate as to how

much of the higher-level semantics of the node-to-node communication abstraction

should be embedded in the hardware design of the network

itself.

The entire area of

network design for parallel computers is bound to be exciting for many years to

come. In particular, there is a strong flow of ideas and technology between parallel

computer networks and advancing ...
