WHILE computer gamers are eagerly awaiting the next generation of platforms, the computer scientists of Lawrence Livermore’s Graphics Architectures for Intelligence Applications (GAIA) project are tracking the rapidly changing technology, but for a different reason. A team, led by John Johnson of the Computation Directorate, is researching graphics processing units (GPUs)—the highly specialized, low-cost, rendering engines at the heart of the gaming industry—to determine how they might be programmed and used in applications other than virtual entertainment.
“Graphics processors are accelerating in performance much faster than other microprocessors,” says Sheila Vaidya, project leader for GAIA. “We have an opportunity to ride the wave of innovations driving the gaming industry.” These processors—traditionally designed for fast rendering of visual simulations, virtual reality, and computer gaming—could provide efficient solutions to some of the most challenging computing needs facing the intelligence and military communities. Real-time data-processing capabilities are needed for applications ranging from text and speech processing to image analysis for automated targeting and tracking.
