Compiler for next MOM update - release 2025.08.000 ?

[dougiesquire]

This issue is just for documentation. I suggest we close after the next MOM update.

Long story short,

• MOM6 throws an internal compiler error (ICE) with %oneapi@2025.0.4 after we update MOM to include NCAR to main (2025-02-10) mom-ocean/MOM6#1653 and GFDL to main 2025-04-23 mom-ocean/MOM6#1664
• FMS throws an ICE with %oneapi@2025.1.1
• Everything compiles successfully with %oneapi@2025.2.0

For the next om3 build release and deployment, I suggest we use:

%oneapi@2025.2.0

no changes to non-access dependencies , although we may consider:

• openmpi 5.0.5 ? (@manodeep / @edoyango / @minghangli-uni - did you have any views, we currently use openmpi 4.1.7)
• FMS ?

for model components, use:

• CICE6.6.1 plus access commits
• MOM6 latest from main plus access commits ?
• Cdeps: cdeps1.0.77
• Cmeps: cmeps1.1.2
• share: main - ( to include make datestamps in rpointer configurable ESCOMP/CESM_share#70 )
• WW3 - https://github.com/ESCOMP/WW3/commits/bd97113f6cf46d9fe068e1c3a1bef72e4cee1a05/ plus access commits
  CDEPS/CMEPS/WW3 are based on current in CESM3.0-alpha branch

openmpi/5.0.8 is now available on gadi - so I will test that out as well (edit test for ESM1.6).

• FMS ?

There's no real reason to update, but no harm either, so maybe let's move to 2025.03. I'm hoping this will be merged soon and we can cherry-pick it into our spack

• MOM6 latest from main plus access commits ?

Yup, I basically have this branch ready to go

Sadly oneapi@2025.2.0 is answer changing - #685 (comment)
