看到了作者的[提问](https://stackoverflow.com/questions/23112219/exception-happened-during-processing-of-request-from-127-0-0-1-xxxx-in-sock), 所以这个问题还是无法解决...？

I noticed that `nvprof` supports `kernel replay` to collect different metrics in several passes for profiling. Are there any documents / implementation details to help?

I mean NVIDIA docs. Because NVIDIA seems to be able to replay kernels in their own software `nvprof`, I'm wondering if there's any docs to shed some light to this...
