[NEST Users] Re: Weights assignment error with mpirun

Hi Xavier, I have now created an issue for this on Github: https://github.com/nest/nest-simulator/issues/3099 But there is another problem with your approach: Even if the code worked with MPI, you would only collect the weights of the connections local to each MPI rank on that rank (i.e., connections with targets on that rank). If normalization per target neuron is what you want, this is fine, if you wanted to normalize all outgoing synapses of a neuron, this would be pretty much impossible when using MPI.

Finn ut hvorfor dette er viktig p? https://aka.ms/LearnAboutSenderIdentification ] Hi! I used 2 and 64 number of processes. An update ... the problem disappears when using "nest.SetStatus(conn,'weight',w_nparray)" instead of the direct assignment "conn.weight=w_nparray". In addition, it also hangs when using "conn.set()" Xavier _______________________________________________ NEST Users mailing list -- users(a)nest-simulator.org To unsubscribe send an email to users-leave(a)nest-simulator.org
