NVIDIA System Management Interface -- v441.08
NVSMI provides monitoring information for Tesla and select Quadro devices.
The data is presented in either a plain text or an XML format, via stdout or a file.
NVSMI also provides several management operations for changing the device state.
NVSMI为Tesla和某些Quadro设备提供监视信息。
数据通过标准输出或文件以纯文本或XML格式显示。
NVSMI还提供了几种管理操作来更改设备状态。
Note that the functionality of NVSMI is exposed through the NVML C-based
library. See the NVIDIA developer website for more information about NVML.
Python wrappers to NVML are also available. The output of NVSMI is
not guaranteed to be backwards compatible; NVML and the bindings are backwards
compatible.
请注意，NVSMI的功能是通过基于NVML C的库公开的。 有关NVML的更多信息，请参见NVIDIA开发人员网站。
也可以使用NVML的Python包装器。 NVSMI的输出是
不保证向后兼容； NVML和绑定是向后兼容的。

释义：
- Driver Version：显卡驱动版本号
- CUDA Version：CUDA版本号
- GPU Name：显卡名称
- Persistence-M：是否支持持久性内存（Persistence-M是一种用于保存显卡驱动状态的特殊内存类型。如果启用了持久性内存，那么在显卡重启或掉电后，内存上的信息仍将保存下来。这种内存类型通常用于保存模型的长期数据，以便在不需要重新加载的情况下加速显卡操作。）
- Bus-Id：显卡的总线ID（Bus-Id是显卡的总线ID，是该显卡在主板上的唯一标识。它是一个数字字符串，用于标识显卡在总线系统中的位置，方便系统识别和管理。每个显卡都有一个不同的总线ID，用于防止显卡混淆，以及为显卡提供管理和配置信息。）
- Disp.A：显卡的显示状态（是否启用）（Disp.A是Display Active的缩写，表示是否有显示器激活，如果有显示器激活，则会显示Yes，否则显示No。显示器激活指的是在电脑系统中打开或使用外接的显示器，使其可以正常显示画面。）
- Volatile Uncorr. ECC：是否启用显
