During Nvidia's fourth-quarter financial results conference call, Nvidia shed a little more light on its acquisition of Ageia and what it plans to do with the firm's PhysX technology. CEO Jen-Hsun Huang revealed that Nvidia's strategy is to take the PhysX engine and port it onto CUDA (Compute Unified Device Architecture), a C-like application programming interface Nvidia developed to let programmers write general-purpose applications that can run on GPUs. All of Nvidia's existing GeForce 8 graphics processors already support CUDA, and Huang confirmed that the cards will be able to run PhysX.
"We're working toward the physics-engine-to-CUDA port as we speak. And we intend to throw a lot of resources at it. You know, I wouldn't be surprised if it helps our GPU sales even in advance of [the port's completion]. The reason is, [it's] just gonna be a software download. Every single GPU that is CUDA-enabled will be able to run the physics engine when it comes. . . . Every one of our GeForce 8-series GPUs runs CUDA."
