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
   • python stand-alone target works already for purely analytically solvable neuron models (adding numeric integrators is work in progress)
     • preparatory step for NESTML targets: SpiNNaker and GPU
2. NEST GPU
   • 🎆 new group!
   • Planning to participate in Helmholtz GPU hackathon this month
3. PyNEST
   • nothing to report beyond hackathon
4. NEST Desktop
   • planned kick-off meeting about NESTML in NEST-Desktop, NRP-NEST-Desktop integration, cosim hub (Elephant)
5. Kernel
   • working on an identified performance bottle-neck in setups with large number of threads per process
6. Installation
   • removing old platfroms from installation targets
   • investigated conda issue #2341

   • working on macos tests
   • started implementation of Docker image testing via selenium based test framework (Robottestframeworg)

In-depth discussion

New features in NEST Desktop

• please check for known issues and report new ones on the NEST Desktop issue tracker
• model documentation preview and link to full documentation
  • model "previews" with automatic model graphs (step current, FI-curve, etc.)
  • models can be imported from GitHub and previewed with default parameters
• view/analysis of results now organized in flexible panels
  • currently very basic analyses
  • for deeper analysis functionality of Elephant (external tool for now)
  • first views on synaptic weight changes
• experiment phases of construction, connection and simulation can be activated separately (for other back-ends like NRP)
• insite back-end
