ICON 2026.04 --enable-openmp with Intel on Levante

Installation

Hello!

Is there a possible way to compile ICON 2026.04 on Levante using Intel with the flag --enable-openmp that does not result in the following error during runs:
“mo_nwp_ecrad_init::setup_ecrad: Using Intel compiler with OpenMP for ecRad in ICON has known issues”?

I look forward to your answers!

Thanks,
Paule

hi!

ecrad and openmp cannot be used together in this release. Hence the warning at runtime.

Instead call the wrapper with --disable-openmp and build the model normally.

the values of nproma and num_io_procs are independent to openmp and ecrad. use them as u like

cheers
