Simulation toolsLarge network simulations put special demands on simulation software. With our roots in traditional computer science, it is natural for us to engage also in simulator development. The SPLIT program developed some years ago [Hammarlund, 1996; Hammarlund and Ekeberg, 1998] is a parallelizing simulator which handles very large network simulations. Our largest network model simulated so far had more than 50000 neurons and 4 million synapses. The See simulator [Djurfeldt et al, 1999] represents the continuation of this development. Efficient neural network simulators are important for another reason as well: they serve as models for how to perform neural network operations efficiently, e.g. in on-board embedded systems. |
