Keywords: Intel Xeon Phi coprocessor, offload, Hetero Stream Library, domain decomposition, HTFETI.

Summary

The Intel® Xeon Phi™ coprocessors are representatives of Intel’s Many Integrated Core (MIC) architecture and represent one of the possibilities how to accelerate scientific or engineering codes. There are several runtimes enabling a computation to be offloaded to the coprocessor. In this paper we compare the Intel Language Extension for Offload (LEO) and several approaches utilizing the Hetero Streams Library (hStreams). As a benchmark we use the dense matrix-vector multiplication since it is a crucial part of our method for acceleration of the HTFETI domain decomposition solver Espreso. We provide an overview of the approaches and present results of numerical experiments.
