1.1 Introduction to Heterogeneous Computing
Heterogeneous computing includes both serial and parallel processing. With heterogeneous computing, tasks that comprise an application are mapped to the best processing device available on the system. The presence of multiple devices on a system presents an opportunity for programs to utilize concurrency and parallelism, and improve performance and power. Open Computing Language (OpenCL) is a programming language ...
