Using a Titan X (Pascal) for a deep learning application I notice in nvidia-smi the following:
Performance State : P2 Clocks Throttle Reasons Idle : Not Active Applications Clocks Setting : Not Active SW Power Cap : Active HW Slowdown : Not Active Sync Boost : Not Active Unknown : Not Active
However the power utilised is way below the max:
Power Readings Power Management : Supported Power Draw : 81.54 W Power Limit : 299.00 W Default Power Limit : 250.00 W Enforced Power Limit : 299.00 W Min Power Limit : 125.00 W Max Power Limit : 300.00 W
Temperature is also low:
Temperature GPU Current Temp : 65 C
Could anybody explain why the clocks are throttled and the performance state is ‘only’ P2?
This is under Ubuntu 17.04 driver 375.66
