Question about memory fault

When the OpenCL kernel tries to access the null pointer, the whole kernel will hang and could not be killed.

I know the ROCm provides a specific fault handler to handle the null pointer error. Does AMDGPU-PRO provide any fault handler like ROCm?

My operating system is Ubuntu 18.04 with AMDGPU-PRO-20.20 driver.

Thank you for your query.  I've forwarded it to the OpenCL team. I'll get back to you once I get their reply.

Thanks.

Re: Question about memory fault

Sorry for this delayed reply.

It seems that we already switched to ROCr backend with the latest amdgpu-pro builds. So I guess the question is sort of irrelevant now.

 

Thanks.
