As Washington and the states pile up mountainous liabilities — $3 trillion for unfunded state pensions, $10 trillion in new federal deficits through 2019, and $38 trillion (or is it $50 trillion?) in unfunded Medicare promises — the U.S. needs once again to call on its chief strategic asset: radical innovation.

One laboratory of growth will continue to be the Internet. The U.S. began the 2000’s with fewer than five million residential broadband lines and zero mobile broadband. We begin the new decade with 71 million residential lines and 300 million portable and mobile broadband devices. In all, consumer bandwidth grew almost 15,000%.

Even a thriving Internet, however, cannot escape Washington’s eager eye. As the Federal Communications Commission contemplates new “network neutrality” regulation and even a return to “Title II” telephone regulation, we have to wonder where growth will come from in the 2010’s . . . .

Almost 40 years ago the CPU — or central processing unit — burst onto the scene and enabled the PC revolution, which was mostly about word processing (text) and simple spreadsheets (number crunching). But today, as Nvidia and AMD’s ATI division add programmability to their graphics chips, the GPU becomes the next generation general purpose processor. (Huang briefly describes the CUDA programmability architecture, which he compares to the x86 architecture of the CPU age.) With its massive parallelism and ability to render the visual applications most important to today’s consumers — games, photos, movies, art, photoshop, YouTube, GoogleEarth, virtual worlds — the GPU rises to match the CPU’s “centrality” in the computing scheme.

Less obvious, the GPU’s attributes also make it useful for all sorts of non-consumer applications like seismic geographic imaging for energy exploration, high-end military systems, and even quantitative finance.

Perhaps the most exciting shift unleashed by the GPU, however, is in cloud computing. At the January 2009 Consumer Electronics Show in Las Vegas, AMD and a small but revolutionary start-up called LightStage/Otoy announced they are building the world’s fastest petaflops supercomputer at LightStage/Otoy’s Burbank, CA, offices. But this isn’t just any supercomputer. It’s based on GPUs, not CPUs. And it’s not just really, really fast. Designed for the Internet age, this “render cloud” will enable real-time photorealistic 3D gaming and virtual worlds across the Web. It will compress the power of the most advanced motion picture CGI (computer generated imaging) techniques, which can consume hours to render one movie frame and months to produce movie sequences, into real-time . . . and link this power to the wider world over the Net. 

Watch this space. The GPU story is big.
