Hi,
I want to know the timing functions that can be called from outside and inside the Kernel subroutine in CUDA fortran. I wanted to know this so as to understand the time spent in actual computations and the time spent in transfers.

Thank you
Regards

Hi Kaustubh,

You might find the following article I wrote helpful. Account Login | PGI. My example program uses Cuda events to show the data transfer time as well as the compute kernel times.

Hope this helps,
Mat
