> GPUs (for rendering and simulation) I'd like to provide a data point for this, btw. There are exchanges for sports gambling (we run one), and some of the most succesful betting syndicates run clusters of hundreds or even low thousands multi-GPU servers to crunch the incoming data on their real-time simulations. The results of this type of crunching are feeds, signaling and strategy shifts for their market makers. I have no doubt investment banks, who operate on an order of magnitude more data, would have something similar. Even if majority of it was used for backtesting.
