Abstract

We consider a variety of solvers for the spline collocation equations arising from the discretisation of elliptic Partial Differential Equations. We study the convergence properties of semi-iterative and conjugate gradient acceleration methods applied to the system of spline collocation equations. The preconditioners tested include incomplete factorisation and SSOR for both the natural and multicolour orderings, domain decomposition based on Schur complement methods with nonoverlapping subdomains, or Schwarz methods with overlapping subdomains, and multigrid methods.

We study the parallelisation of some of the above iterative methods and discuss their advantages and disadvantages. The communication requirements of the methods are discussed when the methods are implemented on distributed memory machines. Results which show that spline collocation methods are very competitive for the solution of BVPs are presented.
