Dear all,
in a previous version of NEST I used to set the RNG seeds like this:
nest.SetKernelStatus({'grng_seed' : value_grngseed}) nest.SetKernelStatus({'rng_seeds' : value_rngseed)})
I already found in newer NEST versions I can set the RNG seed like:
nest.rng_seed = value_rngseed
Is there also a possibility to set the Global RNG seed 'grng' with newer NEST versions?
Thanks!
Benedikt
Dear Benedikt,
From NEST 3.0, there is only a single random seed in NEST, which is then used to seed all other RNGs (global, per thread). This single seed takes the role of the "master seed" used in NEST 2 examples on randomization, but uses a more sophisticated way of generating the individual seeds.
See
https://github.com/nest/nest-simulator/pull/1549 https://github.com/nest/nest-simulator/issues/1440
for background.
Best, Hans Ekkehard
