how can I measure the time.

Hi.

I want to watch the detailed time.

for example, Disk loading time, main memory to device memory transfer time, GPU operation time.

I used nvprof tool. but there was no disk loading I/O time.

and I use asynchronous multi-streaming. It is not the correct time. (it means appearing total time only I want to watch overlapped time)

please tell me how to check all the time stamp
