Open Source High-Performance Computational Chemistry

Tech-X Corporation is pleased to provide an NWChem cloud container in collaboration with UberCloud. NWChem is a set of computational chemistry tools that are able to exploit modern parallel computing environments such as the cloud environments provided by Amazon and Microsoft.

NWChem uses both both quantum and classical methods (and combinations thereof). NWChem has been applied to biomolecules, nanostructures, and solidstate structures. The NWChem set of computational chemistry tools can model both ground and excited states, and includes relativistic effects.

NWChem is developed by a consortium and maintained by the EMSL, located at the Pacific Northwest National Laboratory (PNNL) in Washington State. The source code is distributed as open-source under the terms of the Educational Community License version 2.0 (ECL 2.0), and can be found at the main EMSL site.
