I tried to set up a grid:
When it went to execute the kernel, I get this message:
Cuda error: GPU Kernel execution failed in file ‘xxxx’ in line nn : invalid configuration argument.
If I use only 2 dimensions (dimGrid(nx,ny)) it works.
The docs seems to indicate that the grid can be up to 2 dimensions but doesn’t explicitly indicate that fact. The fact that it’s a dim3 seems to imply that it can handle 3 dimensions.
Is this a limitation in the beta 0.8 version or is this going to be a hard limit in the future?
