The purpose of this page is to share useful information that can help groups with their CUDA projects.

=== Cuda Win32/x64 Library ===
After following the instructions,,provided in today's lecture, to setting up the library and include files in the project properties to run Cuda on VS 2012 Express at home, I still encounter
the linker error; "unable to find cuda_runtime.h". Googling around, there are two ways around this. By default, VS Studio uses the 32bit debugger, which you can change in project properties. You will have to
use the Win32 version of the library directives (ie in my case "C:\Program Files\NVIDIA Corporation\NvToolsExt\lib\Win32") with the default debugger. If use the x64 library files, change the debugger to 64bit (which I neglected and lost a good portion of time). Cheers.

Hope this helps anyone, as it insanely irritated me as changing up the environment path on windows did nothing.

= Visual Studio 2017 and CUDA 9.1 Problem =
I ran into this problem when trying to build '''thrust_sort.cu''' in the Thrust lecture. The only way I was able to build and run successfully was to create a '''CUDA 9.1 project'''. However, in the current version of Visual Studio 2017, unless you set the '''Platform Toolset''' to '''Visual Studio 2015 (v140)''', you will not be able to build and run CUDA 9.1 projects. This can be done by going to project properties, then to the General section, then changing the '''Platform Toolset'''. However, this is where I ran into a problem where Visual Studio would display an error and would not let me change the platform toolset. So I came up with the following workaround and it works:
*If you haven't already done so, install the optional '''Visual Studio 2015 (v140)''' component which is available from the Visual Studio 2017 installer.
*From Visual Studio, create a CUDA 9.1 project, then close the solution.
*Using a text editor, open <project name>.vcxproj
*Add the following as the first element in the XML under the '''Project''' tag:
<nowiki><PropertyGroup>
<CUDAPropsPath Condition="'$(CUDAPropsPath)'==''">$(VCTargetsPath)\BuildCustomizations</CUDAPropsPath>
</PropertyGroup></nowiki>
*Replace all occurrences (there are 2 of them) of v141 with v140.
*Search for "CUDA 9.1" (you will find 2 occurrences). Then replace the first entire line with <code><nowiki><Import Project="$(CUDAPropsPath)\CUDA 9.1.props" /></nowiki></code> and the second entire line with <code><nowiki><Import Project="$(CUDAPropsPath)\CUDA 9.1.targets" /></nowiki></code>.
*Close the file in the text editor then re-open the solution in Visual Studio. You should now be able to add your .cu files, build and run.
