- Abstract
- In this paper we address ourselves to the problem of finding efficient
parallel preconditioner for the interior generalized eigenvalue problem Ax =
λBx, where A and B are large sparse symmetric positive definite matrices. We
consider incomplete LU(ILU)(0) in two variants, Multi-Color block successive
over-relaxation(SOR), and Point-symmetric SOR(SSOR). Our results show that
for small number of processors the Multi-Color ILU(0) gives the best performance,
while for large number of processors the Multi-Color Block SOR does.
