In the present article we describe the implementation of the finite element numerical integration algorithm for the Xeon Phi coprocessor. The coprocessor is an extension of the idea of the many-core specialized unit for calculations and, by assumption, its performance has to be competitive with the current families of GPUs. Its main advantage is the built-in set of 512-bit vector registers and the ease of transferring existing codes from normal x86 architectures. In the article we verify the performance of previously developed OpenCL algorithms for finite element numerical integration, ported to the new Xeon Phi coprocessor architecture. The algorithm is tested for standard FEM approximations of selected problems. The obtained timing results allow to compare the performance of the OpenCL kernels executed on the Xeon Phi and the contemporary GPUs.(original abstract)
