timer value coming zero

Accelerated Computing CUDA CUDA Programming and Performance

Hi,

I use CUDA events for timing my kernels. But I have noticed that it sometime comes 0.00000 for whatever calculations I do.

Why is it so?

Thanks

Perhaps the kernel doesn’t launch? Do you check for errors after launching a kernel?
