kandi X-RAY | nest-simulator Summary

nest-simulator is a C++ library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Keras applications. nest-simulator has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

NEST is a simulator for spiking neural network models that focuses on the dynamics, size and structure of neural systems rather than on the exact morphology of individual neurons. The development of NEST is coordinated by the NEST Initiative. General information on the NEST Initiative can be found at its homepage at

QUESTION

Why is `total_num_virtual_procs` not equal to the amount of MPI processes?

Asked 2020-Sep-11 at 11:25

In the NEST simulator there is the concept of virtual processes. Reading the information on virtual processes I would expect every MPI process to contain at least 1 virtual process, otherwise that MPI process isn't doing anything?

However, when I start 4 MPI processes the kernel status attribute total_num_virtual_procs is 1:

EDIT: TL;DR: The return value of nest.GetKernelStatus('total_num_virtual_procs') was buggy in former NEST versions. Recent versions show the correct number, which by default is one thread per process, so the number of MPI processes.

The number of virtual processes is a free parameter of NEST because it uses a hybrid parallelization scheme with MPI + OpenMP. You may have multiple threads per process, each being its own virtual process, e.g. two processes and four VPs leads to two threads per process:

How to set a Connection's synapse type in the NEST simulator?

Following the tutorial for the Python interface to the NEST simulator I have created 2 neuron populations and connected them:

ANSWER

If I understand the question correctly, you want to connect neurons with specific connectivity patterns.

The default connection pattern of nest.Connect is "all_to_all".

More details about the available patterns are detailed in the Connect documentation.

You can also see the available rules by calling nest.ConnectionRules().

If you're using ipython or jupyter, you can get the docstring locally by typing nest.Connect?.

EDIT: to change synapse type (how it transmits incoming signals), please see the "synapse types" documentation.

You can find examples for tsodyks or quantal_stdp synapses.

An example with your populations would be:
