Abstract

Theoretical methods in chemistry lead to algorithms for the computation of electronic energies and other properties of electronic wave functions that require large numbers of floating point operations and involve large data sets. Thus, computational chemists are very interested in using massively parallel computer systems and in particular the new petascale systems. In this paper we discuss a new programming paradigm that was developed at the Quantum Theory Project to construct electronic structure software that can scale to large numbers of cores of the order of 100,000 and beyond to solve problems in materials engineering relevant to the problems facing society today.
