Hi,

I know that we can choose the number of online CPU cores in the power mode setting. I am just wondering if we can do similar things on the GPU? i.e. choose the number of online GPU clusters/cores?

Best wishes,
Lei

hello XunLei_CHN,

the architecture is different, please check Jetson Xavier NX System-on-Module Data Sheet for reference.
may I know what’s your actual use-case?
thanks

Hi @JerryChang,

Thanks for your reply.

I want to do some execution time measurement for an application when it is using 1SM, 2SMs … 8SMs.

Furthermore, I wonder if I can assign the application to 1SM, 2SMs … 8SMs.

Hi,

Sorry that this is auto scheduled by the GPU driver.
You cannot assign a task with specific SM number.

Thanks.
