Nvidia's kepler: changing the world one computer at a time - Electric Chain Hoists

This week I"m at the Nvidia GTC (GPU Technology Conference),where Nvidia is showcasing the massive advancements it has made inthe realm of supercomputing and the lucrative graphics space. The star of this show is Nvidia's new Kepler platform and what islikely the most beautiful high performance graphics card evercreated - the flagship GeForce GTX 690 . Believe me when I tell you folks, this card is a piece of art, asit is truly beautiful. I"m writing this as I watch the presentation of iconic CEO Jen-Hsun Haung ( you can watch it yourself here ).

He is one of the few people with a stage presence thatapproaches the late Steve Jobs and his keynotes often trend towardthe fascinating. Once again, he is talking about changing the worldof computing and Nvidia tends to be very visual with their examplesand this year is no exception. We"ll use Nvidia's demos totell the story. Angry Glass One of the most impressive demos was one where a virtual bullet wasshot through three pillars of glass. Not only did the glass breakrealistically, but the reflections and refractions of both thebackgrounds and the bullet"s image (once the event was sloweddown enough to watch it) was properly rendered - not only while thebullet was flying, but through the random fractured glass that wasbreaking.

Rendering with this kind of accuracy and reality waspreviously measured in days, yet this demo was done real in time. Getting Wet The next demo showcased the complext properties of water - in realtime - contained in a virtual glass box and reflected in both anNvidia logoed ball and a large golden logo. Now, bear in mind thatwater is particularly hard to render in motion, simply because itacts like liquid glass and the physics occur at a near molecularlevel. However, the demo proved that Kepler was more than capableof accurately rendering the liquid in real time, along with precisereflections and ripples. Playing God Fermi, Nvidia's earlier technology, was first showcased showingduring a demo that knocked folk"s socks off last year when itmodeled the big bang creation of the universe - processing fourhundred million interactions.

It is still impressive, yet Keplerhas increased GPU computing power by a factor of ten, allowingNvidia to model the collision of two mature galaxies. During thekeynote, Nvidia engineers showcased the spectacular collisionbetween our galaxy and the Andromeda Galaxy. Don"t worry,this will happen about 3.5 billion years from now, so I"mpretty sure we still have time to develop a big enough air bag andbuy insurance. Still, simulations like this confirm the existenceof the unseen dark matter that represents ninety percent of themass of the universe. Electric Chain Hoists
