![]() OpenVIDIA was developed at University of Toronto between 2003–2005, in collaboration with Nvidia.Īltimesh Hybridizer created by Altimesh compiles Common Intermediate Language to CUDA binaries. It is, as of 2022, on par with CUDA with regards to features, and still lacking in consumer support. ROCm, launched in 2016, is AMD's open-source response to CUDA. Nvidia launched CUDA in 2006, a software development kit (SDK) and application programming interface (API) that allows using the programming language C to code algorithms for execution on GeForce 8 series and later GPUs. The dominant proprietary framework is Nvidia CUDA. The Khronos Group has also standardised and implemented SYCL, a higher-level programming model for OpenCL as a single-source domain specific embedded language based on pure C++11. OpenCL is actively supported on Intel, AMD, Nvidia, and ARM platforms. OpenCL provides a cross-platform GPGPU platform that additionally supports data parallel compute on CPUs. Programming standards for parallel computing include OpenCL (vendor-independent), OpenACC, OpenMP and OpenHMPP.Īs of 2016, OpenCL is the dominant open general-purpose GPU computing language, and is an open standard defined by the Khronos Group. Mark Harris, the founder of, coined the term GPGPU.Īny language that allows the code running on the CPU to poll a GPU shader for return values, can create a GPGPU framework. ![]() This means that modern GPGPU pipelines can leverage the speed of a GPU without requiring full and explicit conversion of the data to a graphical form. Newer, hardware-vendor-independent offerings include Microsoft's DirectCompute and Apple/Khronos Group's OpenCL. These were followed by Nvidia's CUDA, which allowed programmers to ignore the underlying graphical concepts in favor of more common high-performance computing concepts. This cumbersome translation was obviated by the advent of general-purpose programming languages and APIs such as Sh/ RapidMind, Brook and Accelerator. These early efforts to use GPUs as general-purpose processors required reformulating computational problems in terms of graphics primitives, as supported by the two major APIs for graphics processors, OpenGL and DirectX. A significant milestone for GPGPU was the year 2003 when two research groups independently discovered GPU-based approaches for the solution of general linear algebra problems on GPUs that ran faster than on CPUs. Notably, problems involving matrices and/or vectors – especially two-, three-, or four-dimensional vectors – were easy to translate to a GPU, which acts with native speed and support on those types. General-purpose computing on GPUs became more practical and popular after about 2001, with the advent of both programmable shaders and floating point support on graphics processors. In 1987, Conway's Game of Life became one of the first examples of general-purpose computing using an early stream processor called a blitter to invoke a special sequence of logical operations on bit vectors. In principle, any arbitrary boolean function, including addition, multiplication, and other mathematical functions, can be built up from a functionally complete set of logic operators. These pipelines were found to fit scientific computing needs well, and have since been developed in this direction. GPGPU pipelines were developed at the beginning of the 21st century for graphics processing (e.g. Migrating data into graphical form and then using the GPU to scan and analyze it can create a large speedup. Thus, GPUs can process far more pictures and graphical data per second than a traditional CPU. While GPUs operate at lower frequencies, they typically have many times the number of cores. Įssentially, a GPGPU pipeline is a kind of parallel processing between one or more GPUs and CPUs that analyzes data as if it were in image or other graphic form. The use of multiple video cards in one computer, or large numbers of graphics chips, further parallelizes the already parallel nature of graphics processing. General-purpose computing on graphics processing units ( GPGPU, or less often GPGP) is the use of a graphics processing unit (GPU), which typically handles computation only for computer graphics, to perform computation in applications traditionally handled by the central processing unit (CPU).
