# FiniteVolumeGPU
|
|
|
|
This is a HIP version of the [FiniteVolume code](https://github.com/babrodtk/FiniteVolumeGPU). It is a Python software package that implements several finite volume discretizations on Cartesian grids for the shallow water equations and the Euler equations.

## Setup on LUMI-G
|
|
Here is a step-by-step guide on installing packages on LUMI-G
|
|
|
|
### Step 1: run conda-container
|
|
Installation via conda can be done as:
|
|
```shell
|
|
ml LUMI/24.03 partition/G
|
|
ml lumi-container-wrapper
|
|
```
|
|
```shell
|
|
conda-containerize new --prefix MyCondaEnv conda_environment_lumi.yml
|
|
```
|
|
where the file `conda_environment_lumi.yml` contains packages to be installed.
|
|
|
|
### Step 1 alternative: Convert to a singularity container with cotainr
|
|
```
|
|
cotainr build my_container.sif --system=lumi-g --conda-env=conda_environment_lumi.yml
|
|
```
|
|
|
|
### Step 2: Modify Slurm Job file
|
|
Update the contents of `Jobs/job_lumi.slurm`([link](Jobs/job_lumi.slurm)) to match your project allocation,
|
|
and the directories of where the simulator and Conda container is stored.
|
|
|
|
### Step 3: Run the Slurm Job
|
|
```shell
|
|
sbatch Jobs/job_lumi.slurm
|
|
```
|
|
|
|
### Troubleshooting
|
|
|
|
#### Error when running MPI.
|
|
```
|
|
`MPI startup(): PMI server not found. Please set I_MPI_PMI_LIBRARY variable if it is not a singleton case.
|
|
```
|
|
This can be resolved by exporting this:
|
|
```
|
|
export I_MPI_PMI_LIBRARY=/opt/cray/pe/mpich/8.1.29/ofi/cray/17.0/lib/libmpi.so
|
|
``` |
