Nevermind.

Hi,

Why is there no global variable for the thread dimensions per block, like blockDim is for the number of blocks per grid? Or is there, and I just can’t find it?

Thanks,

Oliver

blockDim gives you the number of threads per block. To get the number of blocks per grid, you use gridDim.
