The First Intel Xeon Phi Coprocessor
This paper describes the first Intel Xeon Phi coprocessor, known by the code name “Knights Corner”, and describes its architecture, features and uses. The reader will be presented this information in an easy to read manner written specifically for a technically-attuned person. While programming should not be called easy, and neither should parallel programming, this paper keeps the fundamentals in clear view: maximizing parallel computations and minimizing data movement. It explains how parallel computations are enabled through scaling (more cores and threads) and vector processing (more data processed at once).
