We released version 0.14 of Accelerate, the embedded high-level language for general-purpose GPU programming. In addition to new constructs for iterative algorithms and improved code generation, this version adds support for the latest CUDA release (5.5) and for OS X Mavericks.
You can find more information on Accelerate’s GitHub page.
Call for help: Accelerate currently works (out of the box) on OS X and Linux. It should also work on Windows, but we need some community help to fix the build process on Windows — for details, please see the recent issue on GitHub.
