Nvidia-smi 不显示 GPU 内存使用情况和进程名称的完整路径

Question

我在 windows 10 PC 上运行命令 nvidia-smi。

为什么它显示 GPU 内存使用为“N/A”？
如何访问每个活动进程名称的完整路径？（目前只显示部分路径）

除了 nvidia-smi 之外，还有其他方法可以访问此类信息吗？

Answer 1

Why does it display GPU Memory Usage as "N/A"?

正如 talonmies 回答的那样，在 WDDM 系统上，NVIDIA 驱动程序不管理 GPU 内存。 WDDM 子系统可以。

你可以通过运行一个命令nvidia-smi --help-query-compute-apps来检查这个，然后它会在"used_gpu_memory" or "used_memory"下显示原因。
我的说 Not available on Windows when running in WDDM mode because Windows KMD manages all the memory not NVIDIA driver.

How do I access full path for each Process names that is active? (right now it only shows a part of the path)

您可以通过运行命令 nvidia-smi --query-compute-apps=pid,process_name,used_memory --format=csv 访问完整路径。
