Exascale Code Generation Toolkit

This effort concerns production and development of the TensorGen performance optimization tool with contributions to the PolyCheck correctness tool. Both tools will be implemented into the comprehensive ECP software stack. Lawrence Livermore National Laboratory leads the project with contributors from Ohio State and Colorado State universities and PNNL’s High Performance Computing group.

xGA: Global Arrays on Extreme Scale Architectures

This effort will scale Global Arrays (GA), the parallel computing library developed at PNNL, for DOE’s Leadership Class computing facilities, including future exascale systems. GA toolkit is incorporated into many computational chemistry packages, including NWChem, meaning it also will be a key part of NWChemEx and have applications for other ECP applications. PNNL leads the project.
