So is the CUDA job scheduling related code in the kernel driver module?

Hope the question is answered.

Do you have a specific question about scheduling? Scheduling is a complex topic so it would help to narrow down the question a bit.

In general though, the kernel driver is responsible for setting up access to the GPU but is not involved in kicking off work for the GPU to process. That's handled entirely in the user-mode drivers.

So, the scheduling of the CUDA-launched kernel is handled by the user-mode driver?

[aaronp24]

Work is submitted to the GPU by the user-mode driver. Scheduling between jobs is handled by the hardware itself.

Oh, I get it, thanks!

Overclocking and undervolt on Linux could be made easier
