Abstract
The objective of this work is to obtain the dominant λ-modes of a nuclear power reactor. This is a real generalized eigenvalue problem, which can be reduced to a standard one. The method used to solve it has been the Implicitly Restarted Arnoldi (IRA) method. Due to the dimensions of the matrices, a parallel approach has been proposed, implemented and ported to several platforms. This includes the development of a parallel iterative linear system solver. To obtain the best performance, care must be taken to exploit the structure of the matrices.
This work has been developed under the support of the Spanish (TIC96-1062-C03-01) and Valencian (FPI-97-CM-05-0422-G) governments.
