Multiprocessor Hardware Configurations

At any point in time, there exist CPU designs that represent the best performance that can be obtained with current technology at a reasonable price. The cost and technical difficulty of pushing the technology further means that the most cost-effective way of increasing computer power is to use several processors. There have been many attempts to harness multiple CPUs and, today, there are many different machines on the market. Software has been the problem for these machines. It is hard to design software that will be portable across a large range of machines and that will scale up well when large number of CPUs are configured. Over many years, Sun has shipped high unit volumes of large-scale multiprocessor ...
