accessing hardware counters measuring performance on NVIDIA G80

Hi, I am doing some research with the CUDA framework but I would like to use hardware performance counters included on the card. I know about NVPerfKit but I think it is not compatible with the current CUDA release.

Is there any way to read counters information?


See the document about profiling in



Thanks, I took a look into it and it could be useful. However, I am wondering whether there will be possible to directly access to the card counters. Is that planned in the next CUDA release?


Yes, in a future release we will have a much more full-featured CUDA profiler.
