Containers

Docker

Dockerfile recipes are available at the repository https://github.com/nwchemgit/nwchem-dockerfiles

Docker images of the master branch are hosted at https://ghcr.io and can be used with the following command

 docker run --shm-size 256m -u `id -u` --rm -v [host_system_dir]:/data ghcr.io/nwchemgit/nwchem-dev input.nw

For example, the following command can be used when starting from the /tmp directory:

 docker run --shm-size 256m -u `id -u` --rm -v /tmp:/data ghcr.io/nwchemgit/nwchem-dev /data/input.nw

where the input file input.nw is located in the /tmp directory.

The following docker command will run NWChem in parallel using three processes

docker run --shm-size 256m  -u `id -u` --rm  --entrypoint='mpirun' -v /tmp:/data ghcr.io/nwchemgit/nwchem-dev  -np 2 nwchem /data/xvdw.nw

This example uses the input file xvdw.nw available on the host directory /tmp

The associated Dockerfile is available at
https://github.com/nwchemgit/nwchem-dockerfiles/blob/master/nwchem-dev/Dockerfile
