Figure 1From: Estimating numerical error in neural network simulations on Graphics Processing UnitsIn repeated runs, results of numerical simulations on GPUs can vary. Mean, standard deviation and range of observed membrane potential of a neuron in a network of 10,000 Izhikevich neurons, 8,000 excitatory and 2,000 inhibitory, with 1,000 random connections each; after only 190 ms simulation the results start to diverge visibly, and after only 210 ms, they differ largely.Back to article page
