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, it?s 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.
