GCR (Generalized Conjugate Residual) and Omin (Orthomin) are iterative methods for approximating the solution of unsymmetric linear systems. The S-step generalization of these methods has been derived and studied in past work. The S-step methods exhibit improved convergence properties. Also, their data locality and parallel properties are enhanced by(More)
Conjugate Gradient-like methods such as Orthomin(k) have been developed to obtain a good numerical approximation to the solution of <italic>Ax</italic> = <italic>f</italic> when the matrix <italic>A</italic> is large, sparse, and nonsymmetric. In s-step variations of these iterative methods, <italic>s</italic> consecutive steps of the one-step methods are(More)
The methods of computational science and engineering have been applied to a wide range of problems such as weather forecasting, cosmology, drug design, and car crash simulation. More recently, high performance computers have been applied to problems in biology (e.g., molecular biology, bioinformatics). The development of CSE as an interdisciplinary field(More)
