Outlook to EasyBuild v3.9.2

The road to EasyBuild v4.0

More aggressive optimizations for NAMD?

  • NAMD recommends more aggressive optimizations than we have.
    • But there is no test suite
    • Davide: It is always difficult with MD codes
    • Damian: tough call
      • Davide: If the developers say it....
      • Damian: Yes, but the build is very brittle, minor changes in compiler version releases break it

New option to skip -Ox flags?

  • Some packages specify their own CFLAGS, CXXFLAGS, etc.
    • New option to avoid EB-defined -Ox flags?
    • Damian: In toolchainopts?

Changing $HOME in the CUDA easyblock

  • The CUDA installer attempts to write in $HOME
    • Should we fix it?
    • $TMPDIR or $EASYBUILD_BUILDPATH?
    • Davide and Bart: No strong feelings regarding where, but should be fixed
    • Damian: Other packages could also need it (eg: Jupyter with extensions)
