BioExcel’s webinar series continues with a presentation by Joe Jordan and Sebastian Keller



As computers become more specialized there is much ongoing work to optimize for next-generation, Exascale systems. One code currently undergoing such efforts is GROMACS, which has a long track record as a widely used and highly performant HPC code.

The core functionality of NB-LIB (NonBonded-LIBrary) is the ability to calculate forces and energies for multiparticle systems, which has applications in a number of scientific disciplines. The goal of NB-LIB is to make the cutting-edge performance of GROMACS available through a high-level C++ API that exposes the GROMACS machinery for computing atomistic forces through a minimal interface. Additionally, NB-LIB ​provides an intuitive API to describe systems and implement novel simulation workflows​ that leverages the current performance of GROMACS, as well as future performance gains.

In this webinar, Dr. Joe Jordan of KTH and Dr. Sebastian Keller of CSCS will give an overview of how to setup and run particle simulations using the NB-LIB API, which is available in the GROMACS 2021 release. They will also discuss ongoing and planned work to expose more aspects of GROMACS performance and enable more varieties of workflows.
