Building and Running WRF on NVIDIA GPUs – Recommended Compilers and Steps

[imendj]

Hello everyone,

I’m working on setting up the Weather Research and Forecasting (WRF) model to run on NVIDIA GPUs and would like guidance on the best approach. Specifically, I’m looking for recommendations on:

1. Compilers: Which compilers support GPU acceleration for WRF?
2. CUDA Support: What are the required CUDA libraries or dependencies for GPU acceleration?
3. Installation and Compilation Steps: Are there any detailed guides on how to properly build WRF with GPU support?
4. Performance Considerations: Any advice on optimizing performance when running WRF on GPUs?

If anyone has successfully set up WRF on an NVIDIA GPU, I’d really appreciate your insights or references to relevant documentation.

Is GPU still not supported by WRF, as mentioned in https://forum.mmm.ucar.edu/threads/gpu-support-for-wrf-mpas.12381/ ?

Or are there more GPU runs possible like the one for microphysics options (WSM5) as stated in https://kmcen.edu.np/enhancement-of-wrf-model-using-cuda/

There may be some versions of WRF out there that support the use of GPUs, but none that are supported by NCAR, unfortunately.
