如何启用CUDA仅用于计算目的，而不用于显示 [英] how to enable cuda only for computing purpose, not for display

问题描述

使用nvidia gt 440 gpu的Iam.它同时用于显示和计算目的，导致计算时性能降低.我可以仅出于计算目的启用它吗?如果是这样，我如何禁用它来使用显示.

Iam using nvidia gt 440 gpu. It is used for both display and computational purpose which leads to less performance while computation. can i enable it only for computational purpose? if so how can i disable it from using display.

推荐答案

这取决于-您是在Windows还是Linux上工作?机器中是否还有其他显示适配器(图形卡)?

It depends -- are you working on Windows or Linux? Do you have any other display adapters (graphics cards) in the machine?

如果您使用的是Linux，则可以在不使用X Windows Server的情况下(即从终端)运行，也可以在不使用SSH的情况下运行SSH(或将显示器连接到另一个适配器).

If you're on Linux, you can run without the X Windows Server (i.e., from a terminal) and SSH into the box (or attach your display to another adapter).

如果您使用的是Windows，则需要第二个显示适配器.只要将显示器连接到GeForce 440 GT，就无法将其仅用于计算目的.其中还包括远程桌面，该远程桌面根本无法工作，除非您拥有Tesla卡，因为WDDM(Windows显示驱动器模型)的设计方式(无法从Session 0(RDP所在的位置)中访问它)服务运行).

If you're on Windows, you need to have a second display adapter. As long as your display is connected to your GeForce 440 GT, there's no way to use it only for computational purposes. That also includes Remote Desktop, which won't work at all unless you have a Tesla card because of the way the WDDM (Windows Display Driver Model) was designed (it can't be accessed from within Session 0, which is where the RDP service runs).
