urn:hdl:2117/105006 An OpenCL-based parallel CFD code for simulations on hybrid systems with massively-parallel accelerators Gorobets, Andrei Trias Miquel, Francesc Xavier Oliva Llena, Asensio Àrees temàtiques de la UPC::Enginyeria mecànica::Mecànica de fluids Computational fluid dynamics OpenCL MPI OpenMP GPU Parallel CFD Finite-volume Structured mesh Dinàmica de fluids computacional A parallel finite-volume CFD algorithm for modeling of incompressible flows on hybrid supercomputers is presented. It is based on a symmetry-preserving high-order numerical scheme for structured meshes. A multilevel approach that combines di erent parallel models is used for large-scale simulations on computing systems with massively-parallel accelerators. MPI is used on the first level within the distributed memory model to couple computing nodes of a supercomputer. On the second level OpenMP is used to engage multiple CPU cores of a computing node. The third level exploits the computing potential of massively-parallel accelerators such as GPU (Graphics Processing Units) of AMD and NVIDIA, or Intel Xeon Phi accelerators of the MIC (Many Integrated Core) architecture. The hardware independent OpenCL standard is used to compute on accelerators of di erent architectures within a general model for a combination of a central processor and a math co-processor.
