摘要
An efficient parallel algorithm is developed for second-order Moller-Plesset perturbation theory with the resolution-of-identity approximation of two-electron repulsion integrals (RI-MP2) to perform MP2 energy calculations of large molecules on distributed memory processors. Benchmark calculations are carried out for taxol (C47H51NO14), valinomycin (C54H90N6O18), and two-layer nanographene sheets (C96H24)(2),which show the high parallel efficiency of the developed algorithm.
