emulation debug mode

Hi All,

I have a kernel which runs with no segmentation faults in the cuda normal mode. But, I get segmentation faults when I switch to emudebug mode. Is that a bad sign? Does it really imply that something is going wrong with my kernel?

Thanks Much.

It’s really pretty likely that you’ve got errors in kernel code. The difference is that the segmentation fault detection mechanisms aren’t there / are different, on the card

Could you please describe briefly about the differences in segmentation fault detection on the card?

Thanks Much.

I detect segmentation faults on the card when the kernel crashes ;)

Wish I could help.
