[harshula]

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

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

BOM

• Adding oneapi on bom-dr:

  • #7857 (Add support for BOM Sentinel (DR) HPC) – Unified Model
  • main/branches/dev/scottwales/vn13.8_sentinel/fcm-make

• Container environments GitHub - MetOffice/ngmo-environments: Next Generation Environments for Momentum® support oneapi at NCI
