Abstract:
The paper considers the performance and energy consumption of Parallella board with Epiphany coprocessor for molecular dynamics simulation. The coprocessor has cacheless many-core architecture, which is a promising energy efficient technology for the evolution of modern supercomputers. The paper describes the development and verification of molecular dynamics simulation program for new platform. It reveals the capabilities of effective parallelization of the code on currently available system taking into account the future development. Comparison of the energy consumption with a modern general-purpose processor Cortex-A53 shows the advantage of the Parallella platform, while there are still opportunities to improve the software.
