摘要：

The full time-dependent Schrodinger equation for 2-electron atoms in intense laser fields is solved using a mixed finite-difference/basis set approach. We discuss Krylov subspace techniques for the propagation of the equation in time, and numerical methods for optimizing the description of the system on a finite-difference lattice. We describe the implementation of a parallelized code based on these numerical methods, and review performance and scaling results of the code on the Gray T3D/E. (C) 1998 Elsevier Science B.V.
