add_cuda on the command line:Ībove is the truncated output from nvprof, showing a single call to add. I think the simplest way to find out how long the kernel takes to run is to run it with nvprof, the command line GPU profiler that comes with the CUDA Toolkit.
Note: on Windows, you need to make sure you set Platform to 圆4 in the Configuration Properties for your project in Microsoft Visual Studio. Moreover, there is a race condition since multiple parallel threads would both read and write the same locations. This is only a first step, because as written, this kernel is only correct for a single thread, since every thread that runs it will perform the add on the whole array. We’ll start with a simple C++ program that adds the elements of two arrays with a million elements each.

You’ll also need the free CUDA Toolkit installed. To follow along, you’ll need a computer with an CUDA-capable GPU (Windows, Mac, or Linux, and any NVIDIA GPU should do), or a cloud instance with GPUs (AWS, Azure, IBM SoftLayer, and other cloud service providers have them). If you are a C or C++ programmer, this blog post should give you a good start.
VISUAL STUDIO CUDA DIM3 HOW TO
So, you’ve heard about CUDA and you are interested in learning how to use it in your own applications. Many developers have accelerated their computation- and bandwidth-hungry applications this way, including the libraries and frameworks that underpin the ongoing revolution in artificial intelligence known as Deep Learning. It lets you use the powerful C++ programming language to develop high performance algorithms accelerated by thousands of parallel threads running on GPUs. But CUDA programming has gotten easier, and GPUs have gotten much faster, so it’s time for an updated (and even easier) introduction.ĬUDA C++ is just one of the ways you can create massively parallel applications with CUDA.
I wrote a previous “Easy Introduction” to CUDA in 2013 that has been very popular over the years. This post is a super simple introduction to CUDA, the popular parallel computing platform and programming model from NVIDIA.
