Meeting Minutes

• New release
  • Release branch has been created.
  • Release should be done by June 1st.
  • Update Developers:Preparing Release to take into account the change to git.
  • The following pages should be updated: Developers:Big_changes Developers:Changes. Send an email to octopus-devel requesting all developers to update these pages.
• Buildbot status
  • New machines in Hamburg using GCC and Intel compilers are up and running. PGI build should be available soon.
  • Plans to add builds with the IBM compiler.
  • We need a new machine to test CUDA builds.
  • Check with Garching about having access to new machines.
• Merge requests policy
  • It has become a bit more difficult to follow what is going on in the code.
  • All developers seem to agree with the current policy.
  • Merge request should be processed in a reasonable amount of time.
  • Changing the tests should be done carefully and always checked in some way.
  • Reasons for changing a test should always be explained in detail.
  • Merge requests that change the tests should be approved by a least two developers.
• LDA+U implementation
  • These developments should be moved to a private repository that is accessible to the other developers.
  • Created a new octopus-private project on gitlab for this kind of developments.
• POP CoE profiling proposal
  • It is not clear what amount of work we need to provide on our side.
  • We can discuss this further with POP people, but none of us as much time to dedicate to this.
• Other topics
  • Non-orthogonal cells: there are still some problems with the stencil generation; several ideas discussed (mehrstellenverfahren)
  • Agreed to have these meetings every three months instead of twice a year.
