How NEST worksΒΆ Built-in timers Basic timers Detailed timers Randomness in NEST Simulations Random numbers in network simulations How to work with randomness in NEST Select the type of random number generator Seed the random number generator The NEST random module Examples of using randomness Randomize the membrane potential Randomize other node parameters Randomize connection parameters Rounding effects when randomizing delays Randomize spatial positions Combine random distributions Randomization from the Python level Random number internals Global and local generators Quantity of random numbers required Collision risk of parallel random number streams Seed parallel random number streams Further background Simulation behavior Time-driven and event-driven approaches Simulation resolution and update interval Set dmin and dmax manually Delays after changes in resolution Spike generation and precision Random numbers: Generators and seeds Random numbers may depend on compiler used Split a simulation into multiple intervals Repeated simulations Monitoring elapsed time
