Solving PDE Problems On Parallel and Distributed Computer Systems Using the NAG Parallel Library

. The NAG Parallel Library enables users to take advantage of the increased computing power and memory capacity offered by multiple processors. It provides parallel subroutines in some of the areas covered by traditional numerical libraries, such as dense and sparse linear algebra, optimization, quadrature and random number generation, as well as utility routines for data distribution, input/output and process management. NAG has recently initiated and is currently participating in the HPCN Fourth Framework project on Parallel I ndustrial NumErical Applica- tions and Portable Libraries (PINEAPL). One of the main goals of the project is to increase the suitability of the NAG Parallel Library for dealing with computationally intensive industrial applications by appropriately extending the range of library routines. Additionally, several industrial applications are being ported onto parallel computers within the PINEAPL project by replacing sequential code sections with calls to appropri..
