GEOS-Chem High Performance Working Group
Welcome to the GEOS-Chem High Performance (GCHP) Working Group wiki page! GCHP represents the next generation of GEOS-Chem with a distributed memory capability enabling efficient scaling across many cores and finer resolution simulations. GCHP also has the advantage of using a cubed-sphere geometry enabling more accurate transport and eliminating the polar singularity inherent to lat-lon grids.
If you are working on a project using GCHP, please add your name and project description to the GCHP projects list located on this page. Also help us pool performance information across systems by contributing your GCHP run information, including your system specifications, on our GCHP Timing Tests page.
If you would like to stay informed of GCHP developments, please join the GEOS-Chem High Performance Working Group mailing list. We also encourage you to join our GCHP Slack workspace. Please contact the GEOS-Chem Support Team with GCHP questions and feedback.
