When I am running my OpenCL code on QuadroFX 4800 NVIDIA graphics card , the kernel is running properly for 1st time. On running for the second instance the Screen resolution is getting disturbed and Kernel is also not . On Rebooting the sys it's fine. My global mem usage on GPU is 300MB . WorkGroup size is 20 x 20
1.5GB OnBoard memory.
Same OpenCL code when run on GeForce 9400 it’s working fine.
