linux gpu 风扇速度,如何在无头节点上调整NVIDIA GPU风扇速度?

以下是一种简单的方法,不需要编写脚本,连接假显示器或摆弄,可以通过SSH执行以控制多个NVIDIA GPU的风扇。它已在Arch Linux上进行了测试。

识别卡的PCI ID:

编辑:我现在不确定什么是最好的方法。以前,我建议过lspci -k | grep -A 2 -E "(VGA|3D)"。但是,这在我的新Threadripper系统上没有提供正确的ID。

有效的方法是sudo startx打开/var/log/Xorg.0.log(或startX在其输出中在“日志文件:”行下列出的任何位置),然后寻找该行NVIDIA(0): Valid display device(s) on GPU- at PCI:。

编辑 /etc/X11/xorg.conf

这是一个三GPU机器的示例:

Section "ServerLayout"

Identifier "dual"

Screen 0 "Screen0"

Screen 1 "Screen1" RightOf "Screen0"

Screen 1 "Screen2" RightOf "Screen1"

EndSection

Section "Device"

Identifier "Device0"

Driver "nvidia"

VendorName "NVIDIA Corporation"

BusID "PCI:5:0:0"

Option "Coolbits" "7"

Option "AllowEmptyInitialConfiguration"

EndSection

Section "Device"

Identifier "Device1"

Driver "nvidia"

VendorName "NVIDIA Corporation"

BusID "PCI:6:0:0"

Option "Coolbits" "7"

Option "AllowEmptyInitialConfiguration"

EndSection

Section "Device"

Identifier "Device2"

Driver "nvidia"

VendorName "NVIDIA Corporation"

BusID "PCI:9:0:0"

Option "Coolbits" "7"

Option "AllowEmptyInitialConfiguration"

EndSection

Section "Screen"

Identifier "Screen0"

Device "Device0"

EndSection

Section "Screen"

Identifier "Screen1"

Device "Device1"

EndSection

Section "Screen"

Identifier "Screen2"

Device "Device2"

EndSection

该BusID咄咄在上一步中确定的PCI ID匹配。AllowEmptyInitialConfiguration即使未连接监视器,该选项也允许X启动。该选件Coolbits可以控制风扇。它还可以允许超频,但这未经我测试。

编辑 /root/.xinitrc

nvidia-settings -q fans

nvidia-settings -a [gpu:0]/GPUFanControlState=1 -a [fan:0]/GPUTargetFanSpeed=75

nvidia-settings -a [gpu:1]/GPUFanControlState=1 -a [fan:1]/GPUTargetFanSpeed=75

nvidia-settings -a [gpu:2]/GPUFanControlState=1 -a [fan:2]/GPUTargetFanSpeed=75

cat

为了方便起见,我使用.xinitrc执行nvidia设置,尽管可能还有其他方法。在这里,我将粉丝人数设置为75%。我阻止X服务器使用空cat命令关闭。这不是严格必要的,但是我发现有时候X卡关闭时,卡会拒绝离开P8低功耗状态,这会给我带来麻烦。第一行将打印出系统中的每个GPU风扇。

启动X

sudo startx -- :0

您可以从SSH执行此命令。输出将是:

Current version of pixman: 0.34.0

监控温度和时钟速度

nvidia-smi可用于观察温度和功率消耗。较低的温度将使该卡具有更高的时钟频率并增加其功耗。您可以sudo nvidia-smi -pl 150用来限制功耗并保持显卡散热,也可以sudo nvidia-smi -pl 300用来使其超频。如果给定150W,我的1080 Ti将以1480 MHz运行,如果给定300W,则将在1800 MHz以上运行,但这取决于工作负载。您可以使用以下命令nvidia-smi -q或更具体地监控其时钟速度,watch 'nvidia-smi -q | grep -E "Utilization| Graphics|Power Draw"'

返回自动风扇管理。

重启。我还没有找到另一种使风扇自动运转的方法。
