In March 2022, [https://lae.mit.edu/team/sebastian-eastham Sebastian Eastham] (GitHub: [https://github.com/sdeastham @sdeastham]) was named '''GCHP Model Scientist''' and the GEOS-Chem High Performance Working Group was disbanded.
Welcome to the [[GCHP|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 [[GEOS-Chem_High_Performance_Working_Group#Current_GCHP_Projectss|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|GCHP Timing Tests page]].

If you would like to stay informed of GCHP developments, please join the [[GEOS-Chem_High_Performance_Working_Group#Email|GEOS-Chem High Performance Working Group mailing list]]. We also encourage you to join our [[GEOS-Chem_High_Performance_Working_Group#Slack|GCHP Slack workspace]]. Please contact the [[GEOS-Chem_Support_Team|GEOS-Chem Support Team]] with GCHP questions and feedback.
