All spack install ...  commands, and any other command generating files on the /software filesystem, must be executed using the sg Linux utility, to make sure the process is run with the correct group ID. All files under /software must have the Linux group of the project they are created by, to contribute towards the correct quota limit. If you fail to do so, these files are accounted for in your personal quote that is meant to limit /home  usage and is much more limited. The syntax is the following:

sg <yourprojectcode> -c 'spack install <spec>'.

For instance, Pawsey staff may install the namd scientific software using the command

sg pawsey0001 -c 'spack install namd'.

$ # the spec looks okay, let's install it
$ sg <projectcode> -c 'spack install namd@2.12 ~cuda fftw=3 interface=python ^fftw@3.3.4 +mpi +openmp +pfft_patches'

Spack would normally download the source code for any packages that it needs to install. The source code for NAMD has a particular restriction that it cannot be downloaded by spack but must be obtained separately:

$ sg <projectcode> -c 'spack install namd@2.12 ~cuda fftw=3 interface=python ^fftw@3.3.4 +mpi +openmp +pfft_patches'
...
==> Installing namd-2.12-tey6bdfijoegx3dkxfc553nckfecmhku
==> No binary for namd-2.12-tey6bdfijoegx3dkxfc553nckfecmhku found: installing from source
...
==> Error: FetchError: Manual download is required for namd. Refer to http://www.ks.uiuc.edu/Research/namd/ for download instructions.

This can be addressed by first manually downloading the source tarball into your current directory where spack will detect it.

$ sg <projectcode> -c 'spack module lmod refresh --delete-tree -y'  # generate LUA modulefiles for Lmod
