Problem with tridiagonal solver in OpenCL sample code page

Hello, apologies if this is in the wrong area, however I couldn’t find an OpenCL area in the forum.

I’ve downloaded and tested the tridiagonal solver from the OpenCL sample code page:

I get good results for performance, however I find that the output of the pcr_small_systems function to be wrong – the solution is very different from the solution produced by the CPU serial solution.

I’m running on a Windows 7 laptop with a GeForce 525M card. Has anyone else seen this problem?
