Efficient Parallel Generation of Partitioned , Unstructured Meshes
In this paper we introduce a method for generating unstructured meshes in parallel which are partitioned in a \good" way. When solving a partial dierential equation on a parallel distributed memory machine, the mesh should be decomposed so that the communication requirement of the numerical solver is minimised and also the amount of work to be performed on each processor is approximately equal....
متن کاملParallel Partitioning of Unstructured Meshes
A method is outlined for optimising graph partitions which arise in mapping unstructured mesh calculations to parallel computers. The method employs a combination of iterative techniques to both evenly balance theworkload andminimise the number and volume of interprocessor communications. They are designed to work efficiently in parallel as well as sequentially and when combined with a fast dir...
متن کاملParallel Refinement of Unstructured Meshes
In this paper we describe a parallel h-refinement algorithm for unstructured finite element meshes based on the longest-edge bisection of triangles and tetrahedrons. This algorithm is implemented in PARED, a system that supports the parallel adaptive solution of PDEs. We discuss the design of such an algorithm for distributed memory machines including the problem of propagating refinement acros...

متن کاملAn Element-Based Concurrent Partitioned for Unstructured Finite Element Meshes
A concurrent partilionerforpartitioning Unstructured finite element meshes on distributed memory architectures is developed. The partitioned uses an element-based partitioning strategy 1[s main advantage over the more conventional node-based partitioning strategy is its modular programing approach to the development of parallel applications. The partitionerfirst partitions element centroids ioi...
