LUMI (CSC)

The LUMI cluster is located at CSC.

Introduction

If you are new to this system, please see the following resources:

Lumi user guide
Batch system: Slurm
Jupyter service ?
Production directories:
- LUMI-P: 4 independent [Lustre](https://docs.lumi-supercomputer.eu/hardware/storage/lumip/#lustre) file systems
- LUMI-F: a fast Lustre file system
- LUMI-O: object storage

Use the following commands to download the WarpX source code and switch to the correct branch:

git clone https://github.com/ECP-WarpX/WarpX.git $HOME/src/warpx

We use the following modules and environments on the system ($HOME/lumi_warpx.profile).

../../../../Tools/machines/lumi-csc/lumi_warpx.profile.example

We recommend to store the above lines in a file, such as $HOME/lumi_warpx.profile, and load it into your shell after a login:

source $HOME/lumi_warpx.profile

Then, cd into the directory $HOME/src/warpx and use the following commands to compile:

cd $HOME/src/warpx
rm -rf build

cmake -S . -B build -DWarpX_DIMS=3 -DWarpX_COMPUTE=HIP
cmake --build build -j 6

The general cmake compile-time options <building-cmake> apply as usual.
