I started this run with the:

• longname

1850_CAM%DEV%LT%GHGMAM4_CLM51%BGC-CROP_CICE_POP2%ECO_MOSART_CISM2%GRIS-NOEVOLVE_WW3_SESP

Instead of

1850_CAM%DEV%LT%GHGMAM4_CLM51%BGC-CROP_CICE_MOM6_MOSART_CISM2%GRIS-NOEVOLVE_WW3_SESP

• resolution:

 ne30pg3_g17

instead of:

ne30pg3_t232

It crashed at initialization with the error

 ERROR: WW3 EXTCDE abort

@fobryan3 and @gustavo-marques: Is there something I should change in the long name?

The PE layout for this run is sharing 1024 tasks for each component, and I thought this version of WW3 has trouble with larger task counts:

$ ./pelayout
Could not write to 'replay.sh' script
Comp  NTASKS  NTHRDS  ROOTPE PSTRIDE
CPL :   1024/     1;      0      1

ESP :      1/     1;      0      1
ESMF_AWARE_THREADING is False
ROOTPE is with respect to 128.0 tasks per node

Could you try to use the same task counts as 091?

HI mnlevy1981,
Thank you so much. I missed the problem with teh pe_layout but it works with your suggestion.

The POP run is 25 years. I am not sure we need more especially that RESTOM is quite large (0.7W/m2 for the first 20 years).
