A survey of Project NEPTUNE, run by the UK Atomic Energy Authority within the UK's ExCALIBUR programme, which is building code to simulate the edge plasma of a fusion reactor at scales approaching exascale. The article describes the core components, covering plasma fluid and kinetic effects and their combination into exascale-ready codes, and indicates the range of other work carried out under the project.

Abstract

This article provides a broad overview of Project NEPTUNE, which aims to create code for simulating edge plasma physics at scales approaching the exascale, and is run by the UKAEA as part of the UK’s ExCALIBUR framework. It is a representative survey of scope and associated outputs, rather than a detailed exposition; the structure is such as to describe the core components of NEPTUNE (efforts toward simulation of plasma fluid and kinetic effects, and their synthesis into exascale-ready combined codes) and then give an indication of the wide range of other work performed under the project.
