CUDA代码会损坏GPU吗？ [英] Can CUDA code damage a GPU?

问题描述

在测试包含内存错误的一块CUDA时，我的屏幕被冻结。重新启动后，我无法再检测到显卡。我的代码是否有可能损坏卡？

While testing a piece of CUDA containing a memory bug, my screen got frozen. After rebooting I cannot detect anymore the graphics card. Is it possible that my code physically damaged the card?

这发生在Ubuntu 14.04下。我不知道卡的模型，因为我不能检测到它，但我记得它是一个相当新的。

This happened under Ubuntu 14.04. I don't know the model of the card, as I cannot detect it but I remember it is a fairly new one.

推荐答案

感谢所有的意见，我解决了这个问题。

Thanks to all the comments I solved the problem.

我将列出我承诺的操作。我不知道他们是否都有效果，但最终问题解决了。

I will list the actions that I undertook. I'm not sure if all of them had an effect but eventually the problem got solved.

首先我断开了显卡，没有它重新启动。之后，我再次插入卡并重新启动。我被抛到一个菜单，据说我在低图形模式下运行。我打开一个 tty （ ctrl + alt + 1 请使用此处说明安装Nvidia驱动程序。

First I disconnected the graphics card and rebooted without it. Afterwards I plugged the card again and rebooted. I was thrown to a menu where it was said that I was running in low graphics mode. I open a tty (ctrl+alt+1) and tried to re-install the Nvidia drivers using the instructions here.

它最初失败了，因为新手的司机正在运行（我认为这是整个问题的主要罪魁祸首）。

It initially failed because the nouveau drivers were running (which I think is the main culprit of the whole problem).

我将此链接列入黑名单。

总之，创建文件/ etc / modprobe.d / blacklist-nouveau.conf ，然后添加：

In summary create the file /etc/modprobe.d/blacklist-nouveau.conf and add:

blacklist nouveau
blacklist lbm-nouveau
options nouveau modeset=0
alias nouveau off
alias lbm-nouveau off

然后我重新启动。然后我的屏幕开始正常工作，但我不能启动 ubuntu 桌面。我重新安装了cuda驱动程序（有一些错误但不是致命错误）。

Then I rebooted. By then my screen started to work properly but I couldn't start the ubuntu desktop. I reinstalled the cuda drivers (there were a few errors but not fatal errors).

然后我重新启动，我的屏幕重新工作。

Then I rebooted and my screen was working again.

回答主要问题：我没有通过测试 CUDA 代码损坏显卡。

Answering the main question: I did not damage the graphics card by testing CUDA code.
