Cholesky decomposition

Does anyone know of an OpenCL Cholesky decomposition implementation?  Maybe just a first attempt? Currently, I'm in the learn-by-example mode.

Cholesky decomposition

I have implemented gauss's naive algorithm but it seems you face issues regarding global synch and hence have to call a kernel iteratively.

Did you make any progress?

Cholesky decomposition

I found this:

Performance Comparison of Cholesky Decomposition
on GPUs and FPGAs
(http://saahpc.ncsa.illinois.edu/10/papers/paper_45.pdf).


I've e-mailed 2 of the authors asking for the OpenCL source.  Haven't heard anything yet.
