News & Contributions

1. Lots of new contributors after SC (thanks everyone!)

• many PRs from new users (Erik Schnetter submitted many PRs right after the talk!)
• Need to merge his fix for lib order in cc wrappers (195)
  • Need to test and merge it with a similar internal fix we have

1. New users on the mailing list (from EPFL, ANL, many others)
2. We moved to github.com/llnl/spack

• update your remotes!

1. Greg Becker & Mario Melara report that Cray integration is working well on NERSC machines.

• NERSC is making packages for Cori now.
  • this is going well, need module-based externals
• Will come with module-based compiler detection & support.
• Mario had a "spackdown" at NERSC
  • Gave Spack tutorial to NERSC users
  • notified people of the google group and telcon

To be merged

1. PR 210: multiple repositories is going to be merged soon.

• restructures /var/spack/packages to /var/spack/repos/builtin
• allows for separate repository directories & package namespaces
• can directly import one package from another via namespaces (e.g., import spack.pkg.builtin.mpich)

2. PR 120: External dependencies

• Depend on system MPI, other packages.

2. Many updates and conversations from the folks at EPFL

• PR 208: multiple tarballs per package
  • Looks good -- needs testing and will be merged.
• Many package updates (mvapich2, fftw, gnuplot, others...)

3. Spack test XML output with nose 202

• Spack test-install command already merged

4. Externals now added directly to sys.path (Peter Scheibel)

• needed for nose
• no more from external import argparse

Already merged

1. PR 86: Open|SpeedShop and associated packages
2. Qt and paraview updates from Ben Boeckel (164, 165, 166, 168)
3. Scogland submitted shell arg handling fix for zsh (205)

• I need to test with bash -- if someone could do that and sign off before I get to it, it would be nice.

1. Greg Lee added -D flag: run Spack under pdb

Bug fixes

1. Issue 206, 238, 217: issues with uninstall failing.

• Most of these were related to the way specs are read in from the database.

1. Issue 209: Fixed bug in some virtual dependency handling

• satisfies() was not working right with multiple vdeps.

1. Issue 203: Figured out some issues with gcc builds

• 5.3.0 should now build properly
• Issues were with RPATHs passed to the internal bootstrap in gcc

Other Bugs

• Issues with libtool using a compiler's name to deduce flags (François Bissey)
  • Similar to prior distutils issues (which we patched)
  • Todd working on a fix for this -- see proposed solution in this thread
• Issue 244
  • Remaining issue relates to handling packages that conditionally extend others.

Work in Progress (WIP)

• Greg and Mario to work on:
  • Using modules as external packages (on cray)
  • Adding sourceme files to compilers (e.g. load Intel's compilervars.sh automatically)
• Custom compiler flags (Greg Becker authored, Todd merging)
• Better PGI & XL compiler support in Boost (Peter Scheibel)
• Paraview (Kitware, Ben Boeckel)

Discussion

• Sorry if I failed to mention anything above -- community continues to grow!
• People want us to test on Macs -- I'd like to
  • Seeing about getting some Mac build agents at LLNL -- likely not happening short-term
• Discuss improving package debug-ability
