Spack is a package manager for supercomputers, Linux, and macOS. It makes installing scientific software easy. Spack isn’t tied to a particular language; you can build a software stack in Python or R, link to libraries written in C, C++, or Fortran, and easily swap compilers or target specific microarchitectures. In this tutorial we’ll use Spack to compile and install weather codes.
First, on the head node - which we connected to via SSM or DCV we’ll run:
export SPACK_ROOT=/shared/spack git clone -b v0.18.1 -c feature.manyFiles=true https://github.com/spack/spack $SPACK_ROOT echo "export SPACK_ROOT=/shared/spack" >> $HOME/.bashrc echo "source \$SPACK_ROOT/share/spack/setup-env.sh" >> $HOME/.bashrc source $HOME/.bashrc
We are going to install the weather codes from a Spack binary build cache/mirror. In order to do this we need to install a few more python packages.
pip3 install botocore boto3
Next we add the mirror and trust the GPG keys that have signed the packages. If you want to verify the GPG keys, they are on OpenGPG.
spack mirror add aws-hpc-weather s3://aws-hpc-weather/spack/ spack buildcache keys --install --trust --force
