Mailing list

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
    • no updates, work as usual
    • see also in-depth discussion below
  2. NEST GPU
    • nothing to report, work as usual
  3. PyNEST
    • working on wheel installation
    • porting tests from SLI to C++ or Python
      • clean-up test style to modern mechanisms
  4. NEST Desktop
    • no report
  5. Kernel
    • nothing to report, work as usual
  6. Installation
    • spontaneous mini-hackathon on Spack install last Friday
  7. Infrastructure
    • HPC centers working on EBRAINS software deployment
  8. Documentation
    • work as ususal
  9. EBRAINS
    • Two HBP Summit 2023 satellite events planned

In-depth discussion

An idea concerning Tsodyks-style synapses

Presentation of Concept

  • dynamics of $x, y, z, u$ are exclusively determined by pre-synaptic neuron
  • could possibly reduce synaptic integration effort by the fan-out factor, possibly $O(10k)$, since only needs to be done once
  • would require special "tsodyks"-variant of source neuron model
  • additional variable to communicate could use float offset parameter for testing
    • more general and much cleaner way would be to allow for a data payload in spike events

Discussion

  • could be similar to Urbanczyk-Senn and Clopath updates
  • need looking into specific (source) neuron models
  • Comments and ideas appreciated!
