Launch kernel simultaneously is it possible ?

hello everyone ;)

I’m working on a CUDA project which filters a picture thanks to a kernel function !
But, now, I’d like to work on my picture by filtering it two times, not just 1 time like before ! and i would like to make it in parallel, so this
is my question :

It is possible to call two Kernel at the same time ? External Image

thanks to help me on this point !

Fermi cards can execute kernels in parallel with no guarantee for depending on available resources. You need to use streams for this. Do you need to run these kernels in parallel or wouldnt it be the same if you just ran them one after another?

I have to see ! :)
