Updates:

  • esmf v8.9.1 -- to match conda-forge
  • mache v3.0.0 -- brings in many important changes, including updates to Aurora, Chrysalis and Perlmutter as well as three new subpackages: mache.deploy, mache.jigsaw and mache.parallel
  • netcdf-c v4.10.0 -- to match conda-forge
  • python v3.14 as default

The Omega submodule is updated to bring in E3SM changes needed to support the latest modules on Aurora, Chrysalis and Perlmutter.

For this round, I will not be testing or deploying on Frontier, though I will attempt to follow up later on that machine.

I have also not yet got oneapi-ifx working on Chrysalis so I will not be testing or deploying that configuration until later.

Things seem to be working. Now waiting for Perlmutter to become available and for Aurora GPU tests to make it through the queue.
