Does anyone use GDB to debug CUDA kernels?

I could never get it working. Does anybody use it? Is it too buggy? I do not see much talk about it on google.

While this isn’t very constructive, I’ve had just the same experience. Never been able to do much useful with the debugger, segfaults for more often than my own programs.

I’m waiting for a new computer, gonna try out the windows debugger any day and see if it’s more useful, I don’t know if it’s the same codebase or not.

I do understand however that it’s probably a complicated job to debug on gpus, so I guess the best thing we can do is file good bug-reports and wait for it to stabilize.
