We present a portable platform, called PIC_ENGINE, for accelerating Particle-In-Cell (PIC) codes on heterogeneous many-core architectures such as Graphic Processing Units (GPUs). The aim of this development is efficient simulations future exascale systems by allowing different parallelization strategies depending the application problem and specific architecture. To end, platform contains basic steps PIC algorithm has been designed test bed algorithmic options data structures. Among that...
We present new results on the strong parallel scaling for OpenACC-accelerated implementation of high-order spectral element fluid dynamics solver Nek5000. The test case considered consists a direct numerical simulation fully-developed turbulent flow in straight pipe, at two different Reynolds numbers Reτ = 360 and 550, based friction velocity pipe radius. is tested several GPU-enabled HPC systems, including Swiss Piz Daint system, TACC's Longhorn, Jülich's JUWELS Booster, Berzelius Sweden....
