    Phoronix: KDE's KStars Working On OpenCL Support

    As part of this year's Google Summer of Code, the KStars program is gaining support for OpenCL acceleration...

    Addendum: since this got posted to Phoronix, itís good to point out that the dramatic improvement is actually from better algorithms, not from using OpenCL. For information, see some of my previous posts on the algorithmic changes.
    This guy has been working on optimizing KStars for a GSOC project, and it's not just OpenCL.

    Old algorithms: 3947ms
    New algorithms (with Eigen on the CPU): 70ms
    New algorithms (with OpenCL): 30ms

      OpenCL works on the CPU and GPGPU, not to mention any other DSP device. Eigen is better served providing easy APIs to call OpenCL directly than competing with it.

      Eigen can't touch OpenCL with its agnostic approach to computations.
