In what case the kernel does not excute at all help

I found some kernels donnot excute on the device at all, does anyone have the same problem? But when I use the emulation, it runs OK. I use redhat enterprise linux 5.3 64bit. and the cuda version is 3.0. :mellow:

the same thing is happening to me. Im launching the kernel, but it never executes

If you add some error checking (so call cudaGetLastError straight after the kernel launch), you will find out why.

How can I see if the kernel is launching?

yeah, I got this error “too many resources requested for launch”, how can I fix it?

Just have a look at this link http://forums.nvidia.com/lofiversion/index.php?t76432.html. May be this can explain the reasons for your problem.
