abstract = {A new class of highly-parallel low-power manycore chips that cope with energy constraints have been unveiled. Sunway's SW26010 and Kalray's MPPA-256 are examples of them, featuring more than two hundred cores in a single low-power chip. Although they may present better energy efficiency than general-purpose multicore processors, architectural characteristics such as their limited amount of distributed on-chip memory make the development of efficient scientific parallel applications a challenging task. In this paper we propose and evaluate a new back-end of PSkel, a framework that provides a single high-level abstraction for stencil programming on CPUs and GPUs, for the low-power manycore MPPA-256 processor. This relieves programmers of the burden of explicitly dealing with communications and the hybrid underlying programming model of MPPA-256. Our results showed that the energy consumption of stencil applications running on MPPA-256 is up to 7.34x and 4.71x lower than on an Intel Xeon E5 multicore and NVIDIA Tesla K40 GPU, respectively.},
