Rapid computation of all sets of electron-repulsion integrals for large-scale molecules

A concept of nonredundant sets of primitive gaussian basis functions is described, which proved highly efficient for rapid computing all sets of electron-repulsion integrals. Combination of the RT parallel algorithm with the nonredundant method demonstrated performance faster than the G amess progra...
