AMD FireStream
AMD FireStream was AMD's brand name for their Radeon-based product line targeting stream processing and/or GPGPU in supercomputers. Originally developed by ATI Technologies around the Radeon X1900 XTX in 2006, the product line was previously branded as both ATI FireSTREAM and AMD Stream Processor. The AMD FireStream can also be used as a floating-point co-processor for offloading CPU calculations, which is part of the Torrenza initiative. The FireStream line has been discontinued since 2012, when GPGPU workloads were entirely folded into the AMD FirePro line. Overview The FireStream line is a series of add-on expansion cards released from 2006 to 2010, based on standard Radeon GPUs but designed to serve as a general-purpose co-processor, rather than rendering and outputting 3D graphics. Like the FireGL/FirePro line, they were given more memory and memory bandwidth, but the FireStream cards do not necessarily have video output ports. All support 32-bit single-precision float ...

AMD FirePro
AMD FirePro was AMD's brand of graphics cards designed for use in workstations and servers running professional Computer-aided design (CAD), Computer-generated imagery (CGI), Digital content creation (DCC), and High-performance computing/GPGPU applications. The GPU chips on FirePro-branded graphics cards are identical to the ones used on Radeon-branded graphics cards. The end products (i.e. the graphics card) differentiate substantially by the provided graphics device drivers and through the available professional support for the software. The product line is split into two categories: "W" workstation series focusing on workstation and primarily focusing on graphics and display, and "S" server series focused on virtualization and GPGPU/High-performance computing. The release of the Radeon Pro Duo in April 2016 and the announcement of the Radeon Pro WX Series in July 2016 marked the succession of Radeon Pro as AMD's professional workstation graphics card solution.

Close To Metal
In computing, Close To Metal (CTM, originally Close-to-the-Metal) is the name of a beta version of a low-level programming interface developed by ATI, now the AMD Graphics Product Group, aimed at enabling GPGPU computing. CTM was short-lived, and the first production version of AMD's GPGPU technology is now called AMD Stream SDK, or rather the current AMD APP SDK (AMD Accelerated Parallel Processing SDK) ) for Windows and Linux 32-bit and 64-bit, which also targets Heterogeneous System Architecture. Overview Close To Metal, originally called THIN (Thin Hardware INterface) and Data Parallel Virtual Machine, gave developers direct access to the native instruction set and memory of the massively parallel computational elements in modern AMD video cards. CTM bypassed the graphics-centric DirectX and OpenGL APIs for the GPGPU programmer to expose previously unavailable low-level functionality, including direct control of the stream processors/ALUs and the memory controllers.

Graphics Core Next
Graphics Core Next (GCN) is the codename for a series of microarchitectures and an instruction set architecture that were developed by AMD for its GPUs as the successor to its TeraScale microarchitecture. The first product featuring GCN was launched on January 9, 2012. GCN is a reduced instruction set SIMD microarchitecture contrasting the very long instruction word SIMD architecture of TeraScale. GCN requires considerably more transistors than TeraScale, but offers advantages for general-purpose GPU (GPGPU) computation due to a simpler compiler. GCN graphics chips were fabricated with CMOS at 28 nm, and with FinFET at 14 nm (by Samsung Electronics and GlobalFoundries) and 7 nm (by TSMC), available on selected models in AMD's Radeon HD 7000, HD 8000, 200, 300, 400, 500 and Vega series of graphics cards, including the separately released Radeon VII. GCN was also used in the graphics portion of Accelerated Processing Units (APUs), including those in the PlayStation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teraflop
Floating point operations per second (FLOPS, flops or flop/s) is a measure of computer performance in computing, useful in fields of scientific computations that require floating-point calculations. For such cases, it is a more accurate measure than measuring instructions per second. Floating-point arithmetic Floating-point arithmetic is needed for very large or very small real numbers, or computations that require a large dynamic range. Floating-point representation is similar to scientific notation, except computers use Binary number, base two (with rare exceptions), rather than Decimal, base ten. The encoding scheme stores the sign, the exponent (in base two for Cray and VAX, base two or ten for IEEE floating point formats, and base 16 for IBM hexadecimal floating-point, IBM Floating Point Architecture) and the significand (number after the radix point). While several similar formats are in use, the most common is IEEE 754-1985, ANSI/IEEE Std. 754-1985. This standard defin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mobile PCI Express Module
Mobile PCI Express Module (MXM) is an interconnect standard for GPUs (MXM Graphics Modules) in laptops using PCI Express created by MXM-SIG. The goal was to create a non-proprietary, industry standard socket, so one could easily upgrade the graphics processor in a laptop, without having to buy a whole new system or relying on proprietary vendor upgrades. Generations Smaller graphics modules can be inserted into larger slots, but type I and II heatsinks will not fit type III and above or vice versa. Dell's Alienware m5700 platform uses a heatsink that will fit Type I, II, & III cards without modification. MXM 3.1 was released in March 2012 and added PCIe 3.0 support. First generation modules are ''not'' compatible with second generation (MXM 3) modules and vice versa. First generation modules I to IV are fully backwards compatible. Some MXM cards have different mounting screw hole configurations, always check the mounting holes of the MXM card and verify that they match ...

Direct Memory Access
Direct memory access (DMA) is a feature of computer systems that allows certain hardware subsystems to access main system computer memory, memory independently of the central processing unit (CPU). Without DMA, when the CPU is using programmed input/output, it is typically fully occupied for the entire duration of the read or write operation, and is thus unavailable to perform other work. With DMA, the CPU first initiates the transfer, then it does other operations while the transfer is in progress, and it finally receives an interrupt from the DMA controller (DMAC) when the operation is done. This feature is useful at any time that the CPU cannot keep up with the rate of data transfer, or when the CPU needs to perform work while waiting for a relatively slow I/O data transfer. Many hardware systems use DMA, including disk drive controllers, graphics cards, network cards and sound cards. DMA is also used for intra-chip data transfer in some multi-core processors.

The Inquirer
''The Inquirer'' (stylized as TheINQUIRER) was a British technology tabloid website founded by Mike Magee after his departure from ''The Register'' (of which he was one of the founding members) in 2001. In 2006 the site was acquired by Dutch publisher '' Verenigde Nederlandse Uitgeverijen'' (VNU). Mike Magee later left The Inquirer in February 2008 to work on the '' IT Examiner''. Historically, the magazine was entirely Internet-based with its journalists living all over the world and filing copy online, though in recent years it has been edited from Incisive Media's offices in London. Although traditionally a ' red top', under ''Incisive Media'' it has put more weight behind its journalism, reducing the number of jibes at companies, and moved instead towards sponsored online debates in association with high-profile organisations, most recently, Intel. ''The Inquirer'' ceased publishing on 19 December 2019, partly due to declining digital advertising revenues. Scoops Sony l ...

Folding@home
Folding@home (FAH or F@h) is a distributed computing project aimed to help scientists develop new therapeutics for a variety of diseases by the means of simulating protein dynamics. This includes the process of protein folding and the movements of proteins, and is reliant on simulations run on volunteers' personal computers. Folding@home is currently based at the University of Pennsylvania and led by Greg Bowman, a former student of Vijay S. Pande, Vijay Pande. The project utilizes graphics processing units (GPUs), central processing units (CPUs), and ARM architecture, ARM processors like those on the Raspberry Pi for distributed computing and scientific research. The project uses statistical simulation methodology that is a paradigm shift from traditional computing methods. As part of the client–server model network architecture, the volunteered machines each receive pieces of a simulation (work units), complete them, and return them to the project's database servers, where th ...

Shader (computer Science)
In computer graphics, a shader is a computer program that calculates the appropriate levels of light, darkness, and color during the rendering of a 3D scene—a process known as ''shading''. Shaders have evolved to perform a variety of specialized functions in computer graphics special effects and video post-processing, as well as general-purpose computing on graphics processing units. Traditional shaders calculate rendering effects on graphics hardware with a high degree of flexibility. Most shaders are coded for (and run on) a graphics processing unit (GPU), though this is not a strict requirement. ''Shading languages'' are used to program the GPU's rendering pipeline, which has mostly superseded the fixed-function pipeline of the past that only allowed for common geometry transforming and pixel-shading functions; with shaders, customized effects can be used. The position and color (hue, saturation, brightness, and contrast) of all pixels, vertices, and/or textures us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
