Title The Design of a Parallel Frontal Solver
Abstract In a previous report (Rutherford Technical Report RAL-94-040), Duff and Scott looked at extending the frontal method for finite-element problems to the multiple front method. This generalization method of the frontal method permits coarse-grained parallelism to be exploited in the solution process. In this report, we discuss the design and development of a general purpose software package HSL_MP42 that implements the multiple front algorithm. HSL_MP42 solves unsymmetric systems of finite-element equations on distributed or shared memory parallel computers. The code is written in Fortran 90 and uses MPI for message passing. A key design feature is a user interface that is straightforward to use while offering flexibility through a number of options. Numerical results for both a model problem and a practical problem arising from groundwater flow calculations illustrate the efficiency of the code and the advantages of the multiple front approach.
