• Ported CoBeL-Spike model from NEST 2.20.0 to NEST 3.4
  
  • translated syntax
  • installed with MUSIC backend and connected to AIgym   
  • tests pass, results written
• started optimizing the STDP learning (Dopamine Synapse weight update)
• started planning a NEST Event in Bochum next year
• deeper networking in NEST developer family
• JEDI benchmark discussions
• performed NEST Desktop stress test
• SIONlib overview and developer discussions
  
  • discussed use-cases and minimum examples
  • decided on next steps for integrations
• discussions on the BeNNch framework structure and onboarding processes
• IAF refractoriness in NESTML
  • discrepancy between NEST code ad documentation detetcted
• build times of large network models (cMAM)
  • profiling of the building time, found slow call for a pandas data lookup.
  • worked towards solution without pandas or different access methods to the complex data structure
• pull-request to STDP synapses: precomputed exponential functions (exp_tables)
• Refinement of model performance prediction and refactoring of benchmark instrumentation (morph)
• Documentation updates for new developments
• discussion on Insite postponed
