Hi all,

I have a problem about concurrent kernel on GTX 570. I test the card it can run concurrent kernel.
I all so see the example of the SDK.
I tried some code but I did not see any improvement using concurrent kernel.
Is there any configuration problem?

Can any one give me some advice or some code successfully using of concurrent kernel?

Thank you!
