How to Create an NVIDIA OpenCL Project in Visual Studio?

NVIDIA OpenCL Project Creation in Visual Studio

Visual Studio users may encounter difficulties in establishing NVIDIA OpenCL development environments. This article addresses common obstacles and guides the reader through the process of creating an NVIDIA OpenCL project.

Prerequisites

Unlike the CUDA toolkit, the NVIDIA OpenCL runtime is embedded within NVIDIA graphics drivers. For setup, one requires OpenCL C header files, OpenCL.lib, and libOpenCL.so (for Linux). Fortunately, the CUDA toolkit includes these essential components. However, sole installation of the toolkit is unnecessary.

File Retrieval

OpenCL header files and the requisite lib file from CUDA toolkit 10.1 can be obtained at:

https://github.com/ProjectPhysX/OpenCL-Wrapper/tree/master/src/OpenCL

Download the OpenCL folder and integrate it into your project's source directory.

Visual Studio Project Configuration

Within the Visual Studio project, navigate to "Project Properties -> C/C -> General -> Additional Include Directories." Specify the path to the downloaded OpenCL include directory, e.g., C:pathtoyourprojectsrcOpenCLinclude.

Next, under "Project Properties -> Linker -> All Options -> Additional Dependencies," include OpenCL.lib. And under "Project Properties -> Linker -> All Options -> Additional Library Directories," specify the path to the OpenCL library directory, e.g., C:pathtoyourprojectsrcOpenCLlib.

Finally, in your .cpp source file, include headers using #include .

Alternative Options

The aforementioned steps apply to AMD/Intel GPUs and CPUs, as well as Linux systems using the following compilation command:

g *.cpp -o Test.exe -I./OpenCL/include -L./OpenCL/lib -lOpenCL

Simplified Approach

To further streamline OpenCL development, consider utilizing the OpenCL-Wrapper available at:

https://github.com/ProjectPhysX/OpenCL-Wrapper

This wrapper simplifies the OpenCL C bindings, eliminating code complexities. It incorporates the OpenCL headers and preconfigured Visual Studio project settings, obviating the need for additional setup.
