About cuda-EvtHandlr output to psacct

After updating the NVIDIA driver from version 440.33.01 to 510.39.01,
cuda-EvtHandlr, which was not output before the update, is now output to psacct.

Is cuda-EvtHandlr now output to psacct in the NVIDIA driver specifications?

It seems to be output when the GPU program is executed,
Is there a way to see what program or command is calling cuda-EvtHandlr?

Could you tell me.

what are those?

it appears to be a process created by the CUDA runtime in some situations in order to handle internal housekeeping tasks

I don’t think there is any specification about it, and I don’t think there is anything you can do about it.

Any expectation that CUDA should use zero system resources is mistaken.

Any expectation that CUDA behavior is static and will never change is mistaken.

The fact that certain aspects of CUDA are unpublished is often for a reason. If there is no public specification, then there is no reason to base your expectations on unpublished information.

If you’d like to see a change in any aspect of CUDA, you can file a bug. The instructions to do so are linked to a sticky post in this sub-forum.

I’m sorry for the late reply.
Thank you for your reply.

When the same program was executed before and after the update of the NVIDIA driver, the commands output to PSACCT were different.
I want to know if the above is the effect of the NVIDIA driver update.

I also want to know if there is a way to check the program or command that calls CUDA-EVTHANDLR if the PSACCT output is changed due to the update.
As a bug report, I would like to check the change of CUDA.

thank you very much.

I don’t have any further information about it, other than what I have mentioned already.

The instructions for bug reports are here.

Thank you for teaching me carefully.
I’ve filed a bug to see what’s changed in CUDA.
