I am using 9250 Firestream card O/S redhat linux
Intially i used clock function to know the time elapsed for processing when using GPU
i reduced the time to 0.9 sec from 6 sec bye changing the kernel and group size
latter i tried with time() function now time function retunts the elapsed time as 12 sec why it so
while running Nvidia both functions are returning same time as 2.5 sec
please give me some suggesions
The behavior is not expected. Do you have a testcase with you which reproduces the problem?
