DVFS using AccelWattch

[Leon924]

Hi, AccelWattch devolpers:

• I am trying to use AceelWattch to evalute power of TITANRTX GPU. In /home/data/userhome/liqiang/lab/gpu/accel-sim-framework/gpu-simulator/gpgpu-sim/README.md, it says :
  The AccelWattch XML configruation file name is set to accelwattch_sass_sim.xml by default and is
  currently provided for SM7_QV100, SM7_TITANV, SM75_RTX2060_S, and SM6_TITANX.

• SO, if I want to run power simulation of TITANRTX(turing arch), should I add a new .x,ml file in ./gpu-simulator/gpgpu-sim/configs/tested-cfgs/TITAN_RTX/* ? can I just only copy the .xml file in /home/data/userhome/liqiang/lab/gpu/accel-sim-framework/gpu-simulator/gpgpu-sim/configs/tested-cfgs/SM75_RTX2060_S into my folder? What considerations should I take during doing this?

• where the DVFS control policy exists in source code ? Can I change this?

The simulator looks for accelwattch_sass_sim.xml in the working directory. You can simply copy over the one you want to use. If you want to use the scripts in ./util, you can create a folder and add the config to this file. https://github.com/accel-sim/accel-sim-framework/blob/dev/util/job_launching/configs/define-standard-cfgs.yml
