During the Model Build meetings, we recently started discussing using the oneapi (ifx) compiler to build models. Let’s collate the compiler flags and use cases here.

## ACCESS-NRI

- Will be documented in: [Add docs about compilers and compiler flags · Issue #36 · ACCESS-NRI/dev-docs · GitHub](https://github.com/ACCESS-NRI/dev-docs/issues/36)

- 07/03/2025 - [Support intel-compiler-llvm (oneapi) compilers · Issue #52 · ACCESS-NRI/access-spack-packages · GitHub](https://github.com/ACCESS-NRI/spack-packages/issues/52#issuecomment-2696034629)

- 07/03/2025 - `icx: error: unsupported argument 'source' to option '-ffp-model=' ` . `ifx` doesn’t trigger an error.

## BOM

- Adding oneapi on bom-dr:

- Container environments [GitHub - MetOffice/ngmo-environments: Next Generation Environments for Momentum®](https://github.com/MetOffice/ngmo-environments) support oneapi at NCI
