Multi GPU SNN Simulation with Perfect Static Load Balancing
We present a SNN simulator which scales to millions of neurons, billions of synapses, and 8 GPUs. This is made possible by 1) a novel, cache aware spike transmission algorithm 2) a model parallel multi GPU distribution scheme and 3) a static, yet very effective load balancing strategy. The simulator further features an easy to use API and the ability to create custom models. We compare the proposed simulator against two state of the art ones on a series of benchmarks using three wellestablished models. We find that our simulator is faster, consumes less memory, and scales linearly with the number of GPUs.
