the launch timed out and was terminated

Hi All,

I’m using Luoshuang’s GPULightmass to build light. I can build the lighting one time before i get the message below. If i try to below a second time i get this error.

2:01:59 PM: GPULightmass Kernel: Line 236: cudaCheckError: the launch timed out and was terminated

Does anyone know what’s causing this?
