===== CP2K Developers Meeting Summary (September 29, 2015) =====

  * The cleanup of the abort/warn/assert handling is finished. A guide describing the best practice concerning error handling is now available [[dev:error_handling| here]].
  * A numerical difference in the results using the PBE functionals between cp2k and cp2k+libxc was found. The reason is that cp2k is using the parameters from the original paper which are given up to 6 digits after the decimal point while libxc and others are using a newer ("exact") value with 12 digits. It was decided to not update the constant in cp2k but document the difference more clearly. Users who rely on the higher precision are encouraged to use the libxc support in cp2k. This way cp2k supports both constants.
  * The recommended and only supported libxc version is the latest released version, which is 2.2.2 at the moment. All further testing will be done using the latest released version only.
  * API break for libdbcsr: for the upcoming support of k-points in cp2k the libdbcsr API needs to be extended to write multiple matrices. Therefore an extension to the respective functions is needed.
  * Most of the tests use now fixed numerical references and can therefore be run everywhere using a simple ''make test''. The remaining tests should/will be fixed eventually.
  * CUDA Toolkit 7.0 is broken in combination with cp2k's usage of threads and its usage is therefore discouraged. CUDA Toolkit 7.5 works again (although the release notes do not mention any specific fixes concerning the problem) and is therefore the recommend version for the CUDA Toolkit 7.x branch.
  * There will be a new CP2K release soon 

===== CP2K version 2.6.2 released (September 16, 2015) =====
This CP2K sub-release provides a couple of back-ported bug fixes (click [[https://sourceforge.net/p/cp2k/code/15893/log/?path=/branches/cp2k-2_6-branch|here]] for details). You can download the tarball of the new version from http://sourceforge.net/projects/cp2k/ and access the manual at http://manual.cp2k.org/cp2k-2_6-branch.

===== CP2K now officially supported by ASE (June 16, 2015) =====
CP2K is now officially supported by the Atomic Simulation Environment.
The ASE is a popular open framework for doing atomistic simulations with Python.
Running a CP2K calculation with ASE can be as simple as this:
<code python>
  calc = CP2K()
  h20 = molecule('H2O', calculator=calc)
  h20.center(vacuum=2.0)
  print h20.get_potential_energy()
</code>

===== CP2K usage on UK National HPC (May 20, 2015) =====

A recently published [[https://www.archer.ac.uk/documentation/white-papers/app-usage/UKParallelApplications.pdf | white paper]] contains data on CP2K usage on the UK National HPC systems since 2009, covering 4 generations of Cray systems.  The data shows that CP2K users are typically able to run at larger core counts than popular plane-wave DFT codes, and may scale up to 24,000 cores or more.
