MolSSI Workshop: Software for Advanced Potential Energy Surfaces

Organizers: Teresa Head-Gordon (U.C. Berkeley) and Susan B. Sinnott (Penn State U.)

Location: Berkeley, California

Dates: 1-2 August 2019

Advanced potential energy surfaces, defined as classical or reactive chemistry treatments beyond widely available classical fixed charge pairwise-additive force fields, are encountering software-related obstacles that inhibit their application to grand challenge chemistry problems:

  • computational cost of the theoretical models;
  • lack of innovation in approximate models and algorithms that can mitigate the cost;
  • limited dissemination to a broad range of community codes;
  • under-developed software interfaces between theoretical models; and
  • lagging quality software implementations on HPC architectures and newer GPU and multicore hardware.

This workshop addressed open software questions across a variety of advanced force fields focused on non-reactive and reactive force fields, which are two communities that rarely intersect. The participants represent a broad cross section of the computational chemistry and materials community involved in software development for force fields in biomolecular, catalysis, and material sciences simulations.
