Horowitz, F. Department of Energy, Office of Science, Advanced Scientific Computing Research. eigensolver is integrated with NWChem successfully. Benchmarks performed with NWChem. Cost scales as N atm^2 to store the data. NWChem aims to provide its users with computational chemistry tools that are scalable both in their ability to treat large scientific computational chemistry problems efficiently, and in their use of available parallel computing resources from high-performance parallel supercomputers to conventional workstation clusters. linear-response property code in NWChem, the first parallel implementation thereof, and applied it to previously impossible problems. "Anyone can build a fast CPU. The NWCHEM codes run from 44 percent to 141 percent faster than on InfiniBand EDR. The GPU-accelerated code is available from GitHub here. The Beta5 release includes very efficient Density Fitted and Cholesky Decomposition (DF/CD) CCSD(T), written by Eugene DePrince. Carry out a significant implementation of a single application or an application suite.
