Evaluating the transport layer of the ALFA framework for the Intel®Xeon Phi™Coprocessor

Aram Santogidis, Andreas Hirstius, Spyros Lalis

Abstract

The ALFA framework supports the software development of major High Energy Physics experiments. As part of our research effort to optimize the transport layer of ALFA, we focus on profiling its data transfer performance for inter-node communication on the Intel Xeon Phi Coprocessor. In this article we present the collected performance measurements with the related analysis of the results. The optimization opportunities that are discovered, help us to formulate the future plans of enabling high performance data transfer for ALFA on the Intel Xeon Phi architecture.
