To start I have created a branch that uses generic thread and block IDs like so:\r\n\r\n int blockId = blockIdx.x\r\n         + blockIdx.y * gridDim.x\r\n         + gridDim.x * gridDim.y * blockIdx.z;\r\n   \r\nint threadId = threadIdx.x +\r\n                blockDim.x * threadIdx.y +\r\n                 (blockDim.x * blockDim.y) * threadIdx.z;\r\n\r\ncurrent unit tests all pass, but this really needs to be exercised with 3D kernel launches\r\n\r\nBTW the branch will be 3d-generic-reduction "}}
