Project team round

Here we discuss topics that need broader attention, for example questions that came up but are outside a single project's scope, larger planned changes/PRs that affect all teams or pending work that is blocked by external factors.

1. Models / NESTML
   • Supporting development of new neuron models with stochasticity and non-GSL forward Euler solvers upon requests by different users.
   • #2254, take out long deprecated *canon* models
2. NEST GPU
   • running validation against latest version of NEST
   • building infrastructure to install similar to NEST
   • integration with PyNEST
   • see sessions at NEST conference
3. PyNEST
   • nothing to report
4. NEST Desktop
   • working on different interfaces towards NRP, NESTML, Elephant
5. Kernel
   • looked more into performance of NEST 3
6. Installation
   • micro-hackathon on Friday for cmake setup of nest-gpu
   • conda for apple-silicon is tricky, needs deeper look, because the standard packaging doesn't work out of the box.
7. Infrastructure
   • added dispatch_event to trigger CI of external model CIs or extension CIs
   • also available as hooks for benchmarking
8. Documentation
   • New structure (#2283) ready for review
   • New theme! Reviewers Wanted!
9. EBRAINS
   • working on common installation on various HPC sites
   • mid-term support request for clustered connectivity is being worked on
