block_grid<1,217,217> invalid configuration argument.

Has anybody else found CUDA 5.0 failing to launch kernels when
gridDim.x < gridDim.y or gridDim.x < gridDim.z ?

Grid [1x217x217] | Block [192x1x1] is rejected with invalid configuration argument.
but <<<217,217,1 192,1,1>>> is ok

Many thanks
Bill

Depends on the compute capability of your card.
Compute capability 1.x doesn’t accept 3D grids, so you can’t do 1x217x217

Ahh. That is probably it. I had forgotten that. I was using level 1.3 (gtx 295)
Many thanks
