Large-Scale Gas Turbine Simulations on GPU Clusters
Tobias Brandvik and Graham Pullan
In this chapter, we present a strategy for implementing solvers for partial differential equations (PDEs) that rely heavily on stencil computations on three-dimensional, multiblock structured grids. As a starting point, a simple stencil computation arising from the discretization of the three-dimensional heat diffusion equation is considered. Building on this example, the steps taken to redevelop a complete computational fluid dynamics solver originally written in Fortran 77 that consists of many complicated stencil computations are then described. The new solver makes extensive use of automatic source code generation for the implementation of its ...
