NWChem Version 5.1.1 Release Notes | ||
(Also available at | ||
http://www.emsl.pnl.gov/docs/nwchem/release-notes/release.notes.5.1.1.html) | ||
|
||
NOTE: These release notes are not a substitute for reading the User Manual! | ||
|
||
They are meant to give a thumbnail sketch of the new capabilities and bug | ||
fixes that are available in NWChem Version 5.1.1. When there is a conflict | ||
between the release notes and the User Manual, the User Manual takes | ||
precedence. | ||
|
||
DFT: | ||
o The DFT-D approach is now available. This allows one to add long-range dispersive corrections to DFT in an empirical fashion. | ||
|
||
DNTMC: | ||
o New Dynamical Nucleation Theory Monte Carlo (DNTMC) module to determine | ||
probability distributions and evaporation rates of molecular clusters | ||
|
||
|
||
NBO: | ||
o Hooks are reinstated that enable users to compile NBO into NWChem | ||
|
||
NWPW: | ||
o Fractional occupation of molecular orbitals added to PSPW | ||
o 2d processor grid for PSPW | ||
o Born-Oppenheimer dynamics option added to PSPW (i.e. task pspw Born-Oppenheimer) | ||
o Unnecessary duplication of the Ewald sum (ion-ion) code removed | ||
|
||
TCE: | ||
o The fourth order many-body perturbation correction (MBPT4) in TCE module has been tremendously improved | ||
o Additional algorithms for the 2-e integral transformation, including | ||
efficient and scalable spin-free out-of-core N5 algorithms | ||
o Hybrid I/O schemes for both spin-orbital and spin-free calculations | ||
which eliminate the memory bottleneck of the 2-e integrals in favor of | ||
disk storage | ||
o Parallel check-pointing and restart for ground-state (including | ||
property) calculations at the CCSD, CCSDT and CCSDTQ levels of theory | ||
o Dynamic dipole polarizabilities at the CCSDTQ level using the linear | ||
response formalism. | ||
