MONC is a high-resolution atmospheric modelling code used in the UK by the Met Office and several UK universities. The NERC community wish to leverage the next generation hardware in ARCHER2 for their scientific ambition. This project aimed to update MONC to tune it to the ARCHER2 architecture and take the opportunity to address two long-standing issues, namely, to update the current FFT dependency and relax a restriction in the code that limits the usable halo size.
This work was funded under the embedded CSE programme of the ARCHER2 UK National Supercomputing Service (http://www.archer2.ac.uk).
