• Mike Collette (LLNL)

Agenda

News

1. New install layout is now merged into develop

• Includes optional dependencies and variants (see Telcon: 2015-05-21)
• Includes YAML configuration files (~/.spack/compilers.yaml, ~/.spack/mirrors.yaml)

2. Matt Legendre has added YAML compiler and mirror configs

• Compiler config now groups compilers by arch
• BG/Q system with same filesystem as Linux machine will show different compilers (fixes an issue)

2. Matt Legendre still working on YAML view configuration

• Simplified syntax for generating symlink trees

3. Other v0.9 features are being added:

• External packages
• External package repositories (directories full of package.py files)
• Compiler flag config & Spec hashing

Issues

• Compiler flags may currently be reordered by Spack's compiler wrappers
  • If there are static libs, or other order-dependent link options interleaved with -L/-I/etc., may have an effect.
  • Will be fixed in compiler wrappers.

Contributions

• YAML config support: Matt Legendre (LLNL)
• ~17 math packages from Saravan Pantham (UC Davis)

General Discussion

• Mike Collette is building lots of packages with Spack
  • ~60-70 packages, built codes against packages.
  • Starting to implement tests after the build in the install() method.
    • Should consider adding test functionality
    • integrate with continuous build (Bamboo at LLNL?)
