Behavior of MDynaMix on Intel Xeon Phi Coprocessor

Over the years, computational science has witnessed exceptional growth, but still lagging in efficient programming to effectively undertake research activities. Today, developments in almost all areas of Science & Technology heavily rely on computational capabilities. The latest TOP500 supercomputing list shows the relevance of computational simulation & modeling using accelerator technologies. Porting, optimization, scaling and tuning of existing High Performance Computing (HPC) Applications on such hybrid architectures is the norm for reaping the benefits of extreme scale computing. This paper gauges the performance of MDynaMix application from Molecular Dynamic domain on Intel Xeon Processor along with Intel Xeon Phi coprocessor. Different test cases were carried out to explore the performance of Intel Xeon Phi cards within the node as well as across the nodes.
