FiniteVolumeGPU

This is a HIP version of the FiniteVolume code. 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: Install rocm-5.4.6 with Easybuild

export EBU_USER_PREFIX=/project/project_xxxxxx/EasyBuild
ml LUMI/24.03 partition/G
ml EasyBuild-user
export PYTHONIOENCODING=utf-8
eb rocm-5.4.6.eb -r

Step 2: run conda-container

Installation via conda can be done as:

ml LUMI/24.03 partition/G
ml lumi-container-wrapper/0.3.3-cray-python-3.11.7

conda-containerize new --prefix MyCondaEnv conda_environment_lumi.yml

where the file conda_environment_lumi.yml contains packages to be installed.

Step 3: 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
