Hi
On Windows 8.1, Cuda 6.5 when i launch
simpleSurfaceWrite.cu in the samples directory
I get access violations, details follow:
The example works, however seems that the runtime tries to fetch more bytes from the global memory for the surface object itself. It tries to fetch 4 more bytes.
Driver issue? cuda runtime issue?
