In this tutorial, I’ll show you everything you need to know about CUDA programming so that you could make use of GPU parallelization, thru simple modifications of your already existing code, running on a boring CPU. The following tutorial was recorded on NVIDIA’s Jetson Orin supercomputer. CUDA stands for Compute Unified Device Architecture, and is a parallel computing platform and application programming interface that enables software to use certain types of graphics processing units for general purpose processing, an approach called general-purpose computing on GPUs. First, I will start by writing a simple function that does a vector multiplication, which is going to run on a CPU. Then we get the same job done using CUDA parallelization on a GPU. Keep in mind that GPU’s have more cores than CPU and hence when it comes to parallel computing of data, GPUs perform exceptionally better than CPUs even though GPUs have lower clock speed and lack several core management features as compared to CPUs. An example reveals that running 64 million massive multiplications on a GPU takes about 0.64 seconds, as opposed to 31.4 seconds when running on a CPU. This translates to a x50 gain in terms of speed, thanks to the parallelization on such a huge number of cores. Amazing ! This means that running a complex program on CPU taking about a month, could be executed in 14 hrs. This could be also faster given more cores. Then, I’ll show you the gains in filling arrays on python on a CPU vs on a GPU. Another example reveals that the amount of time it took to fill the array on a CPU is about 2.58 seconds, as opposed to 0.39 seconds on a GPU, which is a gain of about 6.6x. The last fundamental section of this video is to show the gains in rendering images (or videos) on python. We will demonstrate why you see some film producers or movie makers rendering and editing their content on a GPU. GPU rendering delivers with a graphics card rather of a CPU, which may substantially speed up the rendering process because GPUs are primarily built for fast picture rendering. GPUs were developed in response to graphically intensive applications that taxed CPUs and slowed processing speed. I will use the Mandelbrot set to perform a comparison between CPU and GPU power. This example reveals that only 1.4 seconds of execution is needed on a GPU as opposed to 110 seconds on a CPU, which is a 78x gain. This simply means that instead of rendering a 4K resolution video over a week on a CPU, you could get the same video in 8K resolution rendered in 2 hours on a GPU, if you are using 32 threads. So imagine if you doubled the threads and blocks involved in GPU optimization. ⏲Outline⏲ 00:00 Introduction 00:33 Multiplication gains on GPUs vs CPUs 08:31 Filling an array on GPUs vs CPUs 11:55 Rendering gains on GPU vs CPU 12:35 What is a Mandelbrot set ? 13:39 Mandelbrot set rendering on CPU 17:01 Mandelbrot set rendering on GPU 20:54 Outro 📚Related Lectures Jetson Orin Supercomputer - https://www.youtube.com/watch?v=XN44YcDmtdg Quick Deploy: Object Detection via NGC on Vertex AI Workbench Google Cloud - https://www.youtube.com/watch?v=ByARpzmBIxM Voice Swap using NVIDIA's NeMo - https://www.youtube.com/watch?v=N4nOsJOKc1k 🔴 Subscribe for more videos on CUDA programming 👍 Smash that like button, in case you find this tutorial useful. 👁‍🗨 Speak up and comment, I am all ears. 💰 Donate to help the channel Patreon - https://www.patreon.com/ahmadbazzi BTC wallet - 3KnwXkMZB4v5iMWjhf1c9B9LMTKeUQ5viP ETH wallet - 0x44F561fE3830321833dFC93FC1B29916005bC23f DOGE wallet - DEvDM7Pgxg6PaStTtueuzNSfpw556vXSEW API3 wallet - 0xe447602C3073b77550C65D2372386809ff19515b DOT wallet - 15tz1fgucf8t1hAdKpUEVy8oSR8QorAkTkDhojhACD3A4ECr ARPA wallet - 0xf54bEe325b3653Bd5931cEc13b23D58d1dee8Dfd QNT wallet - 0xDbfe00E5cddb72158069DFaDE8Efe2A4d737BBAC AAVE wallet - 0xD9Db74ac7feFA7c83479E585d999E356487667c1 AGLD wallet - 0xF203e39cB3EadDfaF3d11fba6dD8597B4B3972Be AERGO wallet - 0xd847D9a2EE4a25Ff7836eDCd77E5005cc2E76060 AST wallet - 0x296321FB0FE1A4dE9F33c5e4734a13fe437E55Cd DASH wallet - XtzYFYDPCNfGzJ1z3kG3eudCwdP9fj3fyE #cuda #cudaprogramming #gpu
