Hello,


I don't know how to change the frequency or if it will work, but in your gem5 
python script you can call "m5.simulate(10 * 1e12)" to simulate 10 seconds 
worth of ticks at a time and change the frequency after each call to that.

Subject: [gem5-users] Can I change GPU frequency on the fly while simulating 
gpu-fs?

Hello,

I was trying to simulate a scenario where an user can change gpu's operating 
voltage/frequency while any application is running. So far what I have seen 
while running gpu-fs, we can set a gpu frequency at which the gpu will operate. 
But is it possible to change it for a brief period of time? For example, I am 
running an application which takes 30 seconds to run on gpu. I initialized with 
default gpu frequency 1GHz. At 10th second, I want to set the frequency at 
1.5GHz. Is that possible? If not, how can I do so?

Regards,
Kazi
