For Windows:
Follow these steps once you have installed Vulkan SDK for Windows from https://www.lunarg.com/vulkan-sdk/
-- Install GLFW3 library at suitable location
-- Open the simpleVulkan VS project file.
To add the GLFW3 library path
-- Right click on Project name "simpleVulkan" click on "Properties"
-- In Property pages window go to Linker -> General. Here in "Additional Libraries Directories" edit and add path to glfw3dll.lib
To add the GLFW3 headers path
-- Right click on Project name "simpleVulkan" click on "Properties"
-- In Property pages window go to "VC++ Directories" section. Here in "Include Directories" edit and add path to GLFW3 headers include directory location.
** Make sure to add path to glfw3.dll in your PATH environment variable**
For Linux:
-- Install the Vulkan SDK from https://www.lunarg.com/vulkan-sdk/ and follow environment setup instructions.
-- Install GLFW3 library through your OS package repository. For example: apt-get for Ubuntu and dnf for RHEL/CentOS
-- Install "libxcb1-dev" and "xorg-dev" as GLFW3 is depended on it
-- Add Vulkan and GLFW3 libraries directories to LD_LIBRARY_PATH

# simpleVulkan - Vulkan CUDA Interop Sinewave
## Description
This sample demonstrates Vulkan CUDA Interop. CUDA imports the Vulkan vertex buffer and operates on it to create sinewave, and synchronizes with Vulkan through vulkan semaphores imported by CUDA. This sample depends on Vulkan SDK, GLFW3 libraries, for building this sample please refer to "Build_instructions.txt" provided in this sample's directory
## Key Concepts
Graphics Interop, CUDA Vulkan Interop, Data Parallel Algorithms
## Supported SM Architectures
[SM 3.0 ](https://developer.nvidia.com/cuda-gpus) [SM 3.5 ](https://developer.nvidia.com/cuda-gpus) [SM 3.7 ](https://developer.nvidia.com/cuda-gpus) [SM 5.0 ](https://developer.nvidia.com/cuda-gpus) [SM 5.2 ](https://developer.nvidia.com/cuda-gpus) [SM 6.0 ](https://developer.nvidia.com/cuda-gpus) [SM 6.1 ](https://developer.nvidia.com/cuda-gpus) [SM 7.0 ](https://developer.nvidia.com/cuda-gpus) [SM 7.5 ](https://developer.nvidia.com/cuda-gpus)
## Supported OSes
Linux, Windows
## Supported CPU Architecture
x86_64
## CUDA APIs involved
### [CUDA Runtime API](http://docs.nvidia.com/cuda/cuda-runtime-api/index.html)
cudaImportExternalMemory, cudaExternalMemoryGetMappedBuffer, cudaImportExternalSemaphore, cudaImportExternalSemaphore, cudaSignalExternalSemaphoresAsync, cudaWaitExternalSemaphoresAsync, cudaDestroyExternalSemaphore, cudaDestroyExternalMemory
## Dependencies needed to build/run
[X11](../../README.md#x11), [VULKAN](../../README.md#vulkan)
## Prerequisites
Download and install the [CUDA Toolkit 10.0](https://developer.nvidia.com/cuda-downloads) for your corresponding platform.
Make sure the dependencies mentioned in [Dependencies]() section above are installed.
## Build and Run
### Windows
The Windows samples are built using the Visual Studio IDE. Solution files (.sln) are provided for each supported version of Visual Studio, using the format:
```
*_vs<version>.sln - for Visual Studio <version>
```
Each individual sample has its own set of solution files in its directory:
To build/examine all the samples at once, the complete solution files should be used. To build/examine a single sample, the individual sample solution files should be used.
> **Note:** Some samples require that the Microsoft DirectX SDK (June 2010 or newer) be installed and that the VC++ directory paths are properly set up (**Tools > Options...**). Check DirectX Dependencies section for details."
### Linux
The Linux samples are built using makefiles. To use the makefiles, change the current directory to the sample directory you wish to build, and run make:
```
$ cd <sample_dir>
$ make
```
The samples makefiles can take advantage of certain options:
* **TARGET_ARCH=<arch>** - cross-compile targeting a specific architecture. Allowed architectures are x86_64.
By default, TARGET_ARCH is set to HOST_ARCH. On a x86_64 machine, not setting TARGET_ARCH is the equivalent of setting TARGET_ARCH=x86_64.<br/>
`$ make TARGET_ARCH=x86_64` <br/>
See [here](http://docs.nvidia.com/cuda/cuda-samples/index.html#cross-samples) for more details.
* **dbg=1** - build with debug symbols
```
$ make dbg=1
```
* **SMS="A B ..."** - override the SM architectures for which the sample will be built, where `"A B ..."` is a space-delimited list of SM architectures. For example, to generate SASS for SM 50 and SM 60, use `SMS="50 60"`.
```
$ make SMS="50 60"
```
* **HOST_COMPILER=<host_compiler>** - override the default g++ host compiler. See the [Linux Installation Guide](http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#system-requirements) for a list of supported host compilers.
```
$ make HOST_COMPILER=g++
```
