Speedup with four processors ranged from 3.8 to 4.8. These tests were performed on three of the models used by Migliore et al. (2006): parbulbNet (olfactory bulb (Davison et al., 2003)), pardentategyrus (dentate gyrus of hippocampus (Santhakumar et al., 2005)), and parscalebush (scalable model of layer V of neocortex based on (Bush et al., 1999)), with 500 cells). See text for other details.
