Spack

A snap package for Spack - a flexible package manager and development tool for supercomputers.

Note: The Spack snap is currently only available within the edge channel on the Snap Store as the initial call for testing window is open. Interested in testing this new snap package? See the Spack snap call-for-testing thread on the Snapcraft forum. Please report all this issues and/or suggestions on call-for-testing thread.

Features

Spack is a package manager and development tool for supercomputers. Spack supports installing 7000+ packages and supports several different build systems and compiler backends. Packages installed using Spack peacefully coexist with other packages installed using the distribution package manager. Spack uses RPATH to link dependencies rather than LD_LIBRARY_PATH; there is no need to worry about conflicting libraries messing with binary executables. Each install is unique and will not break other existing installations on your host system.
