How to know % occupancy of GPU
Hi,
I've a kernel and I've generated .cubin for it. It uses 64 threads and 2K of shared memory. Number of registers used are 13. 1) How do I know percentage occupancy of GPU? I'm using CUDA_Occupancy_calculator.xls currently. 2) How do I lessen the register count? will the number of parameters passed to any function play part in occupying registers or only local variables occupy registers? Thanks in advance... |

Wow...
Someone my prove me wrong but I think this is well over the heads of just about everyone here. You might want to try a forum dedicated to CUDA or graphics related programming. Maybe Beyond3D.
