This repo contains Dockerfiles for building CASA 6.5 from source. The possibility of machine tuned containers in explored in this repo.
Built images are available in Dockerhub
https://hub.docker.com/repository/docker/mark9696/casa
For building micro-architecture tuned images you need to know the argument needed to be passed to GCC's -march flag. A simple utility image is present for this.
Image to fetch machine information
This is an Alma 9 image with GCC 11. Running this image will fetch the machine information with gcc -march=native -Q --help=target
podman build -f Dockerfile_march -t fetch_march:0.1 .
podman run --rm fetch_march:0.1
This builds CASA 6.5 from source tuned for the passed microarchitecture, the final image is approx 3.5GB
podman build -t casa:6.5-znver3 -f alma9-slim/Dockerfile --build-arg arch=znver3 .
The nextflow pipeline is used to build multiple images for the list of architectures present in buildImage.nf
nextflow run buildImage.nf
These images are meant for development purposes; this contains devel packages, the CASA source, cache from building CASA, the purpose of this is to modify the source and reuse the cache to build changes. The final image in this method is approx 11GB
Base Alma Linux 9 image with all dependencies to build CASA:
podman build -t casa-env-alma9:0.1 -f alma9/Dockerfile_env .
Image with CASA inside
podman build -t casa:6.5-znver3 -f alma9/Dockerfile --build-arg arch=znver3 .
To run image with CASA inside
# For SELinux based distro RHEL, Centos, Alma, Rocky
# To run casashell
podman run --rm -it -v $PWD:/home/casa:z casa:6.5-znver3
# To run a script file with casa
podman run --rm -it -v $PWD:/home/casa:z casa:6.5-znver3 -c <script_file>
# For other disto
podman run --rm -it -v $PWD:/home/casa casa:6.5-znver3
