Command: GetGlobalRNG

NEST HelpDesk Command Index NEST Quick Reference

Name:
 GetGlobalRNG - return global random number generator
Synopsis:
     GetGlobalRNG -> rngtype
Description:
 
     This function returns the global random number generator which
     can be used in situations where the same sequence of random
     numbers is needed in all MPI processes. The user must EXERT
     EXTREME CARE to ensure that all MPI processes use exactly
     the same random numbers while executing a script. NEST performs
     only a simple test upon each call to Simulate to check if the
     global RNGs on all MPI processes are still in sync.
Examples:
     The RandomDivergentConnect function makes use of numbers
     from the global RNG.
