Introduction

   [   1]

Installed version(s)

The following versions are installed and currently available...

... on environment hpc-env/8.3:

  • AMR-Wind/2022.09.12-intelcuda-2022.01
  • AMR-Wind/2022.09.12-intel-2019b

Loading AMR-Wind

To load the desired version of the module, use the module load command, e.g.

module load hpc-env/8.3
module load AMR-Wind

Always remember: these commands are case-sensitive!

Using AMR-Wind

AMR-Wind is primarily executed by the command amr_wind. This command must be prefixed with "mpirun -np <number_of_allocated_cores>", since the program was built with MPI and accordingly only needs to be called with it. If you want to compute with AMR-Wind by only using CPU, you need to load the `intel` module. Should you want to additionally allocate any GPUs, the `intelcuda`-based module must be loaded.

To find out on how to use AMR-Wind you can just type in mpirun -np 1 amr_wind --help after loading the module to print out a help text to get you started:
