The first part of this paper surveys co-processor approaches for commodity based clusters in general, not only with respect to raw performance, but also in view of their system integration and power consumption. We then extend previous work on a small GPU cluster by exploring the heterogeneous hardware approach for a large-scale system with up to 160 nodes.(More)
Among a variety of grid deformation methods, the method proposed by Liao [4, 6, 18] is one of the most favourables, because it prevents mesh tangling and offers precise control over the element volumes. Its numerical realisation only requires solving a Poisson problem and a system of fully decoupled initial value problems. Many other deformation methods in(More)
