A Scala Prototype to Generate Multigrid Solver Implementations for Different Problems and Target Multi-Core Platforms. |
Abstract | ||
|---|---|---|
Many problems in computational science and engineering involve partial differential equations and thus require the numerical solution of large, sparse nonlinear systems of equations. Multigrid is known to be one of the most efficient methods for this purpose. However, the concrete multigrid algorithm and its implementation depend highly on the underlying problem and hardware. Therefore, changes in the code or many different variants are necessary to cover all relevant cases. We report on a prototype implementation in Scala for a framework that enables abstract descriptions of PDEs, their discretisation, and their numerical solution via multigrid algorithms. From these, data structures and implementations of multigrid components required to solve elliptic PDEs on structured grids can be generated automatically. Two different test problems illustrate the potential of our approach for both CPU and GPU target platforms. |
