Parallel Library for Unstructured Mesh Problems (PLUMP)

The growing class of applicationswhich solve partial differential equations (PDEs) on unstructured adaptive meshes is considered. Solution to such sparse, non-symmetric and in most cases ill-conditioned systems is often obtained using iterative methods. This paper describes the specification and implementationof the Parallel Library for Unstructured Mesh Problems (PLUMP), which supports the tra...

Parallel Unstructured Mesh Partitioning

Scalable Unstructured Mesh Decomposition

As the e ciency of parallel software increases it is becoming common to measure near linear speedup for many applications. For a problem size N on P processors then with software running at O(N=P ) the performance restrictions due to le i/o systems and mesh decomposition running at O(N) become increasingly apparent especially for large P . For distributed memory parallel systems an additional l...

76 Parallel Unstructured Mesh

The use of unstructured mesh codes on parallel machines can be one of the most e cient ways to solve large Computational Fluid Dynamics (CFD) and Computational Mechanics (CM) problems. Completely general geometries and complex behaviour can readily be modelled and, in principle, the inherent sparsity of many such problems can be exploited to obtain excellent parallel e ciencies. An important co...
