Grand Central Dispatch and Open CL Bring Significant Performance Improvements

MovieGate developer Christophe Ducommun has been optimizing his application for the new Snow Leopard operating system with Grand Central Dispatch and OpenCL. His results show approximately 50% increase in video encoding speed when compared to the plain Leopard, while also reducing the CPU load during video decoding by passing some of the work to the graphics processing unit. These results highlight the potential performance gains OpenCL and Grand Central Dispatch can bring as developers begin to take advantage of them.

HPCWire features OpenCL Promises and Potential

While OpenCL is very similar in many respects to NVIDIA's CUDA, it adds features to take advantage of other targets; and though it's quite complex, it has the potential to deliver very high performance, and is much easier than trying to map your computation into OpenGL or graphics primitives. So says Michael Wolfe, with over 30 years in both academia and industry on developing compilers, and is now a senior compiler engineer at The Portland Group, Inc., a wholly-owned subsidiary of STMicroelectronics, Inc.
