Using Modern Multi-/Many-core Architecture for the Engineering Simulations

Abstract

The paper presents authorial method for computer simulation of the process of the casting solidification process using modern multi-/many-core architectures. The authors have focused above all on the GPU compatible with CUDA architecture. Presented in the article method enables division the process of the building a global matrix of coefficients in two independent phases. The first one is performed only once before the start of a computer engineering simulation, the second phase is performed at each time step of computer simulation. The reason for such division is decoupling of computations realised on the GPU from the spatial informations (e.g. physical coordinates of the nodes) contained in the mesh of finite elements. Application of presented method enables the computer scientific simulation in a variety of multicore architectures, such as multi-core CPUs, GPUs, APUs and Intel Phi. The use of computer engineering simulations multi-core processor allows significant acceleration computation, thereby also reduces costs. Presented in the work results have been obtained by using authorial software built by authors from scratch.
