Resum
The work is devoted to the development of efficient parallel algorithms for large-scale simulations of incompressible flows on hybrid supercomputers based on massively-parallel accelerators. The governing equations are discretized using a high-order finite-volume scheme for Cartesian staggered meshes with the only restriction that, at least, one direction is periodic. Its “classical” MPI + OpenMP parallel implementation for CPUs was designed to scale till 100,000 CPU cores. The new hybrid al...
