Welcome to Spack!

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. Learn more here.
