[NEST Users] Re: RunManager and STDP connections

Hi! I agree with Jan that the connections should be updated regardless of you using |RunManager| or not. Can you please send a minimal reproducer script that triggers the erroneous behavior? It is quite hard to reproduce the error from just your verbal description. There seems to be a misconception about the purpose of stimulation backends here. The |mpi| backend you are referring to allows to send stimulation device parameters from and /external/ application to NEST at runtime via MPI (hence the name of the backend). When using this backend, the file in |{data_path}/{data_prefix}{label}/{node_id}.txt| (|{node_id}| being the device’s node ID, not the target neuron’s) will specify the MPI address where data comes from (i.e. the external application), /not/ the data you want to set (the rate in your case). Please see these documentation pages for more information: * https://nest-simulator.readthedocs.io/en/v3.3/guides/stimulate_the_network.… * https://nest-simulator.readthedocs.io/en/v3.3/models/stimulation_backend_mp… Cheers, Jochen! ​ -- Dr. Jochen Martin Eppler (he/him) Simulation and Data Lab Neuroscience Jülich Supercomputing Centre Institute for Advanced Simulation --------------------------------------------------------------------- Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
