Bootstrap GCC, LLVM and NVHPC, and build an HPC software stack based on OpenMPI, with a few unique features:

1. parallel package builds with single jobserver for all builds;
2. avoiding relocation issues by fixing the install path to a new directory /some-dir of choice (no root access required);
3. fast, in-memory builds.

Requirements:

• spack
• bwrap (when not already building inside a sandbox)

Usage:

1. Copy Make.user.example to Make.user and change some variables¹.
2. Run make -j$(nproc) to bootstrap compilers and packages².
3. Run make store.squashfs to bundle those in a squashfs file.

Unprivileged mounts

The squashfs file can then be mounted using squashfs-mount or squashfuse

Generating modules

There's no modules.yaml file right now, but generating modules goes along those lines:

modules:
  'default:':
    arch_folder: false
    roots:
      tcl: /path/to/tcl/modules
    enable:
    - tcl
    tcl:
      projections:
        all: '{name}/{version}-{compiler.name}-{compiler.version}'
      all:
        autoload: none
        filter:
          environment_blacklist: ['LD_LIBRARY_PATH', 'LIBRARY_PATH', 'CPATH']
