![]() Platform Version OpenCL 1.2 CUDA 11.0.228 Here's the ouput of clinfo: Number of platforms 3 I installed ocl-icd-opencl-dev and "Compute runtime" (NEO) : So the issue is that my integrated intel GPU isn't detected. When I run this code, I get the following output: 1 GPU devices are detected. Std::cout << "OpenCL_C_Version: " << device.OpenCL_C_Version() << std::endl Std::cout << "imageSupport: " << device.imageSupport() << std::endl Std::cout << "available: " << device.available() << std::endl Std::cout << "name: " << device.name() << std::endl Std::cout << context.ndevices() << " GPU devices are detected." << std::endl //This bit provides an overview of the OpenCL devices you have in your computerįor (int i = 0 i < context.ndevices() i++)Ĭv::ocl::Device device = vice(i) ![]() Std::cout << "Failed creating the context." << std::endl If (!context.create(cv::ocl::Device::TYPE_ALL)) ![]() Std::cout << "OpenCL is not available." << std::endl I run this C++ code to detect the available devices: #include I use Ubuntu 18.04 and my processor is an Intel i7-9750H (with UHD Graphics 630). I would like to run another one aside, which would use OpenCV with OpenCL. The Series6XT GPU inside the iPad Air 2 performs surprisingly well, keeping up with Nvidia’s much-lauded Tegra K1 - assuming the Series7XT delivers as promised, it should put PowerVR licensees like Apple in very good stead.I currently have a program running all the time using my Nvidia GPU. This makes sense, given how it’s only been less than a year since Series6XT was announced, and the mobile market - like the PC market - is now very much about evolutionary updates, rather than revolutionary changes that generally upset developers and break compatibility. Overall, it sounds like the Series7XT is mostly just a refined version of the Series6XT, with the addition of some juicy new hardware features (tessellation, virtualization, FP64 for supercomputing). (At this point, all of Imagination’s claims are based on software-based emulation of the design - which is how every chip designer tests and verifies a new design before going through the very expensive and time-consuming tape-out process.) I’m not entirely sure how Imagination Technologies squeezed another 60% out of much the same USC design I guess we’ll have to wait until we actually get our hands on some hardware to see how the performance claims stand up. As of the A8X SoC (iPad Air 2), the six-cluster PowerVR GX6650 is just about neck-and-neck with the Kepler-based GPU inside Nvidia’s Tegra K1 SoC. Imagination Technologies, a fabless chip designer based in England, is mostly known for its PowerVR brand of GPUs, which have powered Apple’s SoCs since the A4 (the iPhone 4/original iPad). Now, almost every cellular device in the world has a Qualcomm chip inside it - and almost every mobile device uses a CPU licensed from ARM Holdings. For the longest time, these companies were the designers of obscure, low-power chips for embedded solutions and other non-sexy products - and then, with the popularization of the smartphone in 2007, everything changed very quickly. Imagination Technologies, much like Qualcomm, ARM Holdings, and other players in the mobile space, have had an utterly crazy few years. There’s also full support for the Android Extension Pack, a new feature in Android 5.0 Lollipop (for supported GPUs) that brings hardware tessellation, ASTC texture compression, and other neat “desktop-class” graphics features. The top-end Series7XT GT7900 will feature 16 clusters (somewhat equivalent to a GPU “core”), for a total of 512 ALUs and peak theoretical performance above 1 teraflop - or around the same as an Nvidia GTX 750. Imagination is claiming a performance boost of 60% over its Series6 GPUs, clock for clock, which for a single 12-month generational leap is pretty darn impressive. Imagination Technologies has detailed its next-gen PowerVR Series7 GPUs - and boy are they beastly. ![]()
