2020 12 21 Open NEST Developer Video Conference
- Welcome
- Review of NEST User Mailing List
- Project team round
- In-depth discussion
- NeuronGPU
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.
- Models / NESTML
- no updates, looking into triplet STDP synapse from mailing list
- PyNEST
- no news
- nest-server implemented on pynest, new feature mpi-enabled nest-server coming soon (tested and benchmarked already, docs being updated, PR in January)
- Kernel
- #1741 "free buffers" ready for review
- Installation
- discussed "make install-nodoc", still working on it
- Infrastructure
- no news
- Documentation
- no news
- EBRAINS
- no news
- (Feature) Random number generation
- no news, work still going on
- (Feature) Automated Testing
- discussing issue with parsing nosetest outputs, need to be converted to standard formats, e.g. junit
- (Feature) Extension Module System
- no news, work still going on
- Presentation on "NeuronGPU" by Bruno Golosio
- comparing NEST with NeuronGPU (and with GeNN, CarlSim) w.r.t.
- average firing rate
- coeff. of variation of inter-spike intervals (CV-ISI)
- pearson coefficient
- network building time
- simulation time
- contriburtions of spike handling, neuron dynamics and Poisson generators
- Models:
- Potjans&Diesmann (for comparison NEST, GeNN, NeuronGPU)
- Balanced network Izhikevich+STDP network (for compaison with CarlSim)
- Balanced network AdEx neurons (for cluster mode with ~50 nodes)
- NEST NGPU interface
- by implementing new NEST neuron model to bridge between the simulations
- interface ports and direct generation of nest SpikeEvents
- validation with exact overlapping of membrane potentials across whole simulation
- proposal to transfer NEST initiative
