- If you are setting cflags and noticing that there are conflicting flags in the compiler invocations this will likely help
- See: http://spack.readthedocs.io/en/latest/packaging_guide.html#compiler-flags

High variability in the reported coverage (Massimiliano):

started on January 2, 2018
issue that tracks the problem is #6887
turned off auto-cancellation of builds on Travis
now (January 11) numbers seem stable, but the reports are apparently ~0.5% below the real coverage because we had to turn off concurrency=multiprocessing in unit tests

Mario: cross compiling build dependencies on cray
- Need better support for static builds (separate build deps PR should help)
- cray machines adding a --host argument to configure
- Working on configure for frontend/backend builds
- Working on architecture
Patrick: testing out distributing spack-built packages with disk images (dmg) on Mac OS using sparseimage
- Main advantage: doesn't require relocation (mounts to the volume name it was created with, and the original spack installation is to a volume of the same name)
- Also supports relocation of compilers (the original installation directories are part of the compiler binaries)
Mario: distributing a survey to consultants to collect use cases
Daniel: having a spack presentation next Wednesday
Mario: there are some cray-specific PRs
- Architecture concretization (syncing frontend target and frontend os)
- Change operating system format: current format is "cray-CNL-haswell" and new format is "cray-cnl6"
- Add params to directory layout: separate into platform, operating system, and target
