The Numerical Algorithms Group Ltd is currently participating in the European HPCN Fourth Framework project on Parallel
Industrial
Num
Erical
Applications and
Portable
Libraries (PINEAPL). One of the main goals of the project is to increase the suitability of the existing 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 appropriate parallel library routines.
A substantial part of the library material being developed is concerned with the solution of PDE problems using parallel sparse
linear algebra modules. This talk provides a number of performance results which demonstrate the efficiency and scalability
of core computational routines — in particular, the iterative solver, the preconditioner and the matrixvector multiplication
routines. Most of the software described in this talk has been incorporated into the recently launched Release 1 of the PINEAPL
Library.
