Abstract In this paper we report our experiences in porting the FEASTFLOW
software infrastructure to the Intel Xeon Phi coprocessor. Our efforts involved both the evaluation of
programming models including OpenCL, POSIX threads and OpenMP and typical
optimization strategies like parallelization and vectorization. Since the straightforward
porting process of the already existing OpenCL version of the code
encountered performance problems that require further analysis, we focused our efforts on the ...
