Ready for the Dawn of Aurora

Argonne Leadership Computing Facility recently named 10 computational research projects for its Aurora Early Science Program. Among them, the PNNL-led NWChemEx Exascale Computing Project that aims to develop a new version of the popular computational chemistry code, NWChem. The time on Aurora will enable the NWChemEx team to develop, test, design, and implement NWChemEx on a computing system geared directly for exascale computing.
