请教 nvidia-smi 命令中 Perf参数的含义,这个P0~P12是软件根据设备参数自己评估的还是人为设置的。
A服务器上的V100显示的是P0
B服务器上的RTX-4090显示的是P8
我比较疑惑RTX-4090这个值为啥是P8
我看NVIDIA官方文档对于这个参数的解释是:
The GPU performance state APIs are used to get and set various performance levels on a per-GPU basis. P-States are GPU active/executing performance capability and power consumption states. P-States range from P0 to P15, with P0 being the highest performance/power state, and P15 being the lowest performance/power state. Each P-State maps to a performance level. Not all P-States are available on a given system. The definition of each P-States are currently as follows: - P0/P1 - Maximum 3D performance
- P2/P3 - Balanced 3D performance-power
- P8 - Basic HD video playback
- P10 - DVD playback
- P12 - Minimum idle power consumption
