PCCP Perspective Published
Developers of NWChem at EMSL were the lead authors on a perspective article in the highly ranked PCCP journal on utilizing high performance computing for chemistry and parallel computational chemistry. The article and cover were published in Phys. Chem. Chem. Phys. 12, 6896 (2010).
NWChem released as open-source
On September 30, 2010 NWChem version 6.0 was released. This version marks a transition of NWChem to an open-source software package. The software is being released under the [Educational Community License 2.0] (ECL 2.0). Users can download the source code and a select set of binaries from this site.
New functionality, improvements, and bug fixes include:
- Greatly improved memory management for TCE four-index transformation, CCSD(T), CR-EOMCCSD(T), and solver for EOMCCSD
- Performance and scalability improvments for TCE CCSD(T), CR-EOMCCSD(T), and EOMCCSD
- TCE based static CCSD hyperpolarizabilities
- New exchange-correlation functionals available in the Gaussian DFT module
- Range-separated functionals: CAM-B3LYP, LC-BLYP, LC-PBE, LC-PBE0, BNL. These functionals can also be used to perform TDDFT excited-state calculations
- SSB-D functional
- Double hybrid functionals (Semi-empirical hybrid DFT combined with perturbative MP2)
- DFT response calculations are now available for order 1 (linear response), single frequency, electric field and mixed electric-magnetic field perturbations.
- Spin-orbit now works with direct and distributed data approaches
- Greatly improved documentation for QM/MM simulations
- Bug fix for DISP: Empirical long-range vdW contribution
- Bug fix for Hartree-Fock Exchange contributions in NMR
- Plane-wave BAND module now has parallelization over k-points, AIMD, and Spin-Orbit pseudopotentials
- Plane-wave modules have improved minimizers for metallic systems and metadynamics capabilities
