Chapter 5. Scalar Optimization and Usability

Key Points

  • Before beginning a parallel optimization project, make sure a good effort at scalar performance optimization has already been invested.

  • A compiler that targets your processor and features advanced optimizations such as automatic vectorization, interprocedural optimization, and profile-guided optimization can substantially improve performance of your application.

  • Applying usability features of your compiler such as those aiding compatibility, compile time, and code size, can substantially improve development efficiency.

As discussed in Chapter 4, a variety of tools are available to help with multi-core software development. After reading that chapter you may be led to believe the next step is ...
