Overview of Platform Architectures,In order to optimize software you need to understand hardware. In this chapter we give you a brief overview of the typical system architectures found in the high-performance computing (HPC) today. We also introduce terminology that will be used throughout the book.

Addressing System Bottlenecks, application in a system. Even if the application is well optimized and it may seem that no additional improvements are possible by tuning it on the other levels, it still has a bottleneck, and that bottleneck is in the system the program runs on. The tuning starts and ends at the system level.
