CUDA is a application programming interface (API) created by Nvidia that allows software developers to use a CUDA-enabled graphics processing unit (GPU) for general purpose processing in parallel. ie CUDA gives direct access to the GPU's instruction set

CUDA provides both:

  • a low level API (CUDA Driver API, non single-source)
  • and a higher level API (CUDA Runtime API, single-source).

Windows installation

Device Manager Nvidia Display

Nvidia Display Cuda M1200

Microsoft Visual Studio

A supported version of Microsoft Visual Studio. See the installation page requirement for the list of supportED product. I have installed Community 2019.

Visual Studio Installer

  • Verify that the checksum match with the Nvidai checksum. For 10.1, this was the list. Example with fciv
fciv.exe -add cuda_10.1.105_418.96_win10.exe -md5
// File Checksum Integrity Verifier version 2.05.

  • Create the env CUDA_PATH that points to the directory given in the Table 4. CUDA to the Visual Studio .props locations. For instance, C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\extras\visual_studio_integration\MSBuildExtensions. You should find in it the file CUDA 10.1.props, If you don't do it, you got a problem with the loading of the proejct due to a bad $(CUDAPropsPath)
  • When opening the solution file Samples_vs2017.sln at the root of the samples, it should take time to load.

Nvidia Sample Cuda Loading

  • Go to the deviceQuery Project

Nvidia Cuda Sample Devicequery Project

  • Change the runtime tool set and the sdk if needed in the project properties (Right Click)

Nvidia Cuda Sample Devicequery Property

  • Build

  • Test the binary created. The important outcomes are that a device was found, that the device(s) match what is installed in your system, and that the test passed.
