Dynamic textures clCreateFromGLTexture2D not mapping

Accelerated Computing CUDA CUDA Programming and Performance

Attached is a simple simulation of Conway’s Game of Life on a 2D grid (and associated kernel). With #define FULL_INTEROP 0 it works fine. With #define FULL_INTEROP 1, it uses clCreateFromGLTexture2D() and texture maps a square, rather than using clCreateImage2D() and glDrawPixels(). Although this version also executes without error message, the original textures are never updated - on NVIDIA platforms (G80, GT200, GF100). It works fine on a Mac! Am I missing some NVIDIA-specific context property?

Thanks for any help,

p.s. The site would not let me upload the kernel, newlife.cl, without renaming it. Please change the
name back to newlife.cl before executing.
