NVidia Quadro FX 3800 的 CUDA 安装

Question

我在带有 Nvidia Quadro FX 3800 的工作站上安装 CUDA 7.0（与 TensorFlow 一起使用）时遇到问题。我想知道这是不是因为不再支持 GPU。

安装驱动程序 (340.96) 似乎工作正常：

$ sh ./NVIDIA-Linux-x86_64-340.96.run

Installation of the NVIDIA Accelerated Graphics Driver for Linux-x86_64
(version: 340.96) is now complete. Please update your XF86Config or
xorg.conf file as appropriate; see the file
/usr/share/doc/NVIDIA_GLX-1.0/README.txt for details.

但是，我认为我可能遇到以下问题：

$ ./cuda_7.0.28_linux.run --kernel-source-path=/usr/src/linux-headers-3.13.0-76-generic
The driver installation is unable to locate the kernel source. Please make sure
that the kernel source packages are installed and set up correctly. If you know
that the kernel source packages are installed and set up correctly, you may pass
the location of the kernel source with the '--kernel-source-path' flag.

是不是因为CUDA不支持这个显卡导致安装失败？

我按照链接路径：https : //developer.nvidia.com/cuda-gpus > https://developer.nvidia.com/cuda-legacy-gpus > http://www.nvidia.com/object/product_quadro_fx_3800_us。 html，我会认为 Quadro FX 3800 支持 CUDA（至少在开始时）。

Answer 1

是的，CUDA 7.0 及更高版本不再支持 Quadro FX 3800 GPU。

支持该 GPU 的最后一个 CUDA 版本是 CUDA 6.5。

这个答案和这个答案可能很有趣。您的 QFX 3800 是计算能力为 1.3 的设备。

如果您查看 CUDA 7 附带的发行说明，您会发现取消对这些早期 GPU 的支持的通知。同样，较新的 CUDA 驱动程序版本也不支持这些 GPU。
