Xeon Phi Application Design and Implementation Considerations

Parallel programming on any general-purpose processor such as Intel Xeon Phi requires careful consideration of the various aspects of program organization, algorithm selection, and implementation to achieve the maximum performance on the hardware.

One of the key challenges in developing a parallel code for the Xeon Phi coprocessor is to develop and parallelize offload computations on as many as 244 threads to exploit the massive parallel computing power provided by the coprocessor. To achieve that degree of parallelism, application developers often face the following challenges: ...
