In this paper we present a new scheme for parallelization of the Successive Over-Relaxation method for solving the Poisson equation over a 3-D volume. Our new scheme is both simple and effective, outperforming the conventional Red-Black scheme by a factor of 16 on an NVIDIA GeForce GTX 590 GPU, a factor of 11 on an NVIDIA GeForce TITAN Black GPU and a factor of 5 on an Intel Xeon Phi. The speed-up...
There is a growing need for ever more accurate climate and weather simulations to be delivered in shorter timescales. Hardware Acceleration using GPUs or FPGAs could potentially result in much reduced run times or higher accuracy simulations. We studied the Weather Research and Forecasting Model in order to assess if GPU acceleration of this type of Numerical Weather Prediction code is both feasible...
In this paper we report our work on the parallelisation of a Nested Sampling Monte Carlo algorithm used in the nuclear physics field of hadron spectroscopy. The purpose of the application is to fit a set of parameters in a nuclear physics model based on the observations of the beam properties. We used both OpenCL and OpenMP to parallelise the existing code. Our aims were to achieve parallelisation...
