Over at the Nvidia blog, Can Ozdoruk writes that, due to high demand for the new K20 GPUs, the company’s GPU Test Drive Program provided early access to a number of researchers so they could benchmark their codes.
The results are in. Two-thirds of the users (65 percent) who took the test drive reported speed-ups of 2x or more, right out of the box, without making any code changes. You can just imagine what they will achieve with a couple code optimizations. And, this was done on a wide range of real scientific applications like GROMACS, GTC and CST, not on synthetic benchmarks, showing how the new Kepler GPUs can make an immediate impact on research.
