Neuron Model for a Generalized LIF Neuron (No alpha or exponential shaped psc)
by shanka19＠purdue.edu 14 Feb '20

14 Feb '20

Hello NEST Users, I wanted to create a neural network with generalized LIF Neurons. I do not want any exponential or alpha shaped PSCs. Since I cannot draw to describe its shape, I am posting a link from google images to help understand what I mean by a generalized LIF. https://www.google.com/url?sa=i&url=https%3A%2F%2Fwww.researchgate.net%2Ffi… Thanks in advance!

Realtime access to spikes in simulation
by Benjamin Staude 04 Feb '20

04 Feb '20

Hi NEST-Team, To use the NEST-Simluator in an interactive installation, I would need to 1) have access to the spike in the network in realtime, and 2) send signals (spikes) to neurons in the simulation in realtime. For 1), I could imagine writing the spike-times to a file and then reading that file while the simulation is running. However, I currently don’t see an option for 2). Then I heard that you are actually working on module that would enable realtime I/O-access. Is that the case? And, if so, is there a timeline?

Stop Printing Simulation Details on Terminal (NEST)
by shanka19＠purdue.edu 04 Feb '20

04 Feb '20

Hi, I wanted to know how to stop printing the simulation details on my terminal window. For instance I can see the number of open mpi process, simulation time being printed every time I run a model. I do not want to see the details on my terminal screen, is there a way to do it?

Using GPU's to run NEST simulaton
by Daphne Cornelisse 04 Feb '20

04 Feb '20

Hi NEST-team, I would like to run a simulation of > 1000 neurons, and to make my computing time faster I am looking into how to use parallel computing with NEST. I have seen this <https://www.nest-simulator.org/parallel-computing/> page but I can't seem to find anything about using the cloud (e.g. google cloud, colab etc.) and the use of GPU's. I am quite new to this so it could be I missed something. - Is it possible to use a GPU for the nest simulations? - Are the some resources I could learn from? Thank you! Best, Daphne
