# FiniteVolumeGPU
|
|
|
|
This is a HIP version of the [FiniteVolume code](https://github.com/babrodtk/FiniteVolumeGPU) (work in progress). 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 0: load modules
|
|
```
|
|
ml LUMI/23.03 partition/G
|
|
ml lumi-container-wrapper
|
|
ml cray-python/3.9.13.1
|
|
```
|
|
|
|
### Step 1: run conda-container
|
|
Installation via conda can be done as:
|
|
```
|
|
conda-containerize new --prefix MyCondaEnv conda_environment_lumi.yml
|
|
```
|
|
where the file `conda_environment_lumi.yml` contains packages to be installed.
|
|
|
|
### Step 2: Set the env. variable to search for binaries
|
|
```
|
|
export the bin path: export PATH="$PWD/MyCondaEnv/bin:$PATH"
|
|
```
|
|
### An alternative: Convert to a singularity container with cotainr
|
|
```
|
|
cotainr build my_container.sif --system=lumi-g --conda-env=conda_environment_lumi.yml
|
|
```
|
|
|
|
### 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/8.1.27/ofi/cray/14.0/lib/libmpi.so
|
|
```
|
|
### Install hip-python
|
|
```
|
|
python -m pip install -i https://test.pypi.org/simple/ hip-python==5.4.3.470.16
|
|
```
|
|
|
|
The testing was done with this specific version `hip-python==5.4.3.470.16`
