Hello 1538356357,

May I ask you to sign messages to the NEST User mailing list with your name as a courtesy to all community members?

Concerning your question, NEST distributes neurons using a simple round-robin algorithm among the virtual processes, which again are systematically mapped to MPI ranks and OpenMP threads. Exceptions are recording and stimulation devices, which are replicated on each virtual process and devices support MUSIC, which are replicated once per MPI rank.

Best regards,

Hans Ekkehard

Dear NEST community：
         We all know that distributed computing is carried out in Nest, and neurons are distributed to each neuron through polling. However, considering the load balancing and sparsity of communication, this is a NP hard problem. Should we adopt some other methods, such as directed graph segmentation technology. Whether this will be considered in Nest, or whether graph segmentation is helpful in SNN simulation.

If you can spare time to reply, thank you very much
