Fedora + Eclipse + CUDA6.0

为了运行Caffe，在Fedora 17系统中安装了CUDA6.0，某天突然发现开始菜单中有NSight Eclipse Edition，于是好奇地打开看看和Visual Studio有什么区别。

打开时过场动画如下：

弹出对话框如下，我们选择默认工程位置。

进入Eclipse后，选择File -> New -> CUDA C/C++ Project，弹出对话框如下：

工程名输入first，工程类型选择Executable/Import CUDA Sample，工具链选择CUDA Toolkit 6.0，下一步。

这里选择gencode选项，由于已经检测到GeForce610M的计算能力为2.1，我们只选PTX 2.0和GPU 2.1两项，点下一步。

这里保持默认，下一步。

仍然默认，完成。

这里打开的工程是convolutionFFT2D。在左侧Project Explorer中first文件夹上右键，选择Build Project，状态如下：

编译无误，我们可以仍然在first文件夹上右键，选择Run As... Local Application，在Console中得到输出结果如下：

 
[/root/cuda-workspace/first/Debug/first] - Starting...
GPU Device 0: "GeForce 610M" with compute capability 2.1
