Turning Electricity Into Money: How GPUs Are Accelerating High Finance
 
http://blogs.nvidia.com/wp-content/u...ecsheader2.jpgHedge Connection will join several dozen other companies sharing their ideas at the Emerging Companies Summit, at the fourth annual GPU Technology Conference, to be held in San Jose, Calif., next March.

Video gamers rely on GPUs to deliver dazzling fast-twitch action. Scientists use banks of GPUs to simulate reactor cores and predict changes in global climate. That may sound like an unlikely set of skills to bring to the world of high finance ' but it turns out GPUs are a perfect fit.

Bankers, hedge funds, actuaries, and other hyper-connected capitalists are increasingly relying on GPUs to help manage money. Just talk to Rob Arthurs, CEO of Hedge Connection, which helps bring together fund managers and qualified investors. 'Why wouldn't hedge fund managers want the same tools being used to build supercomputers?' Arthurs asks.

From nuclear science to the world of finance

GPUs have long been used to tackle one of the toughest computing chores in modern finance: Monte Carlo simulations. Originally developed by nuclear scientists at the Los Alamos National Laboratory, Monte Carlo simulations can be used to model complex systems. Because GPUs are parallel processors ' they rely on large numbers of cores working on different parts of a problem simultaneously ' they can run algorithms involved in such simulations more efficiently than machines that rely on CPUs alone.

The result: GPUs are now being used by some of the finance industry's biggest players. In 2008, market news giant Bloomberg began using GPUs to help it grind through the Monte Carlo simulations it uses to calculate prices for hard-to-price securities. Standard Live Canada uses GPUs to help it manage complex financial instruments such as derivatives.

And in 2011, JP Morgan became the first major bank to detail its use of GPUs publicly, claiming that NVIDIA Tesla GPUs helped it tackle calculations Monte Carlo and finite difference algorithms as much as 100 times faster while slashing the cost of running these calculations by 80%.

Keeping it low key

While major financial players are making headlines, hedge funds have been quietly scooping up GPUs as well. Few will detail how they use them: the most successful hedge funds don't want to give competitors an edge, Arthurs explains. 'They really don't like talking about it,' he says.

While the banks and hedge funds using GPUs are staying quiet, the companies supplying them with the software needed to unlock the power of GPUs are proliferating. These tools range from powerful, general purpose tools widely used by mathematicians and scientists ' such as Wolfram Mathematica ' to far more specialized products. Synerscope (see 'Synerscope: Data Analysis for the Rest of Us') use GPUs to help financial institutions ' and other customers ' visualize complex data sets. Quantifi Solutions and Murex ' whom we'll profile in an upcoming post ' use GPUs to speed up the sophisticated analytics software used to assess the risk of a portfolio.

Coupled with powerful new tools, even a handful of GPUs can give hedge funds computing power possessed by only the most advanced supercomputers a decade ago. And a few are buying scores ' even hundreds ' of GPUs. 'There's one that likes to say they can turn electricity into money,' Arthurs says.
