Abstract
The resolution of the identity (RT) approximation to the Hartree-Fock method was implemented within the NWChem suite of ab initio programs for parallel computers. After a description of the method, a detailed account of the implementation is given. We present a sample calculation and compare its performance and accuracy to an ''exact'' direct SCF calculation. Problems and limitations of the method are also discussed. (C) 1997 John Wiley & Sons, Inc.
