Traditionally, the performance-limiting attributes of a multi-processor machine are memory bandwidth, the need to maintain state coherence, and simple synchronisation issues, or some combination of these. As the system size increases, so too does the relative cost overhead of solving these problems. The SpiNNaker engine is a million core system with over eight terabytes of distributed memory whose fundamental design axioms neatly sidestep these problems: the processors are not synchronised, the memory is not coherent, and the inter-processor communication is non-deterministic. How, then, can we perform meaningful computations with this architecture?
