clone

cd /home/ubuntu/sgi/your_folder_name
git clone git@github.com:SGI-2023/INSR-hybrid.git
cd INSR-hybrid

run program inside docker container

docker run --gpus all -it -v $HOME:/home/ubuntu sgi-2023

The above command will start a docker container. Once you are in this container,

cd /home/ubuntu/sgi/your_folder_name/INSR-hybrid
bash scripts/xxx.sh

To detach from the container, you can find do: https://www.howtogeek.com/devops/how-to-detach-from-a-docker-container-without-stopping-it/

To re-enter the container

docker attach docker_id

docker_id is the number after root@ on your command line when you created the container.

Feel free to do whatever crazy things inside the container. No problem! But do not do anything crazy outside. However, you will need to do version control (i.e., git pull/commit/push) outside the docker.

Experiments

Run each shell script under scripts/ for the examples shown in the paper:

bash scripts/xxx.sh

For instance,

bash scripts/advect1D.sh
