Xeon Phi
Xeon Phi was a series of x86 manycore processors designed and made by Intel. It was intended for use in supercomputers, servers, and high-end workstations. Its architecture allowed use of standard programming languages and application programming interfaces (APIs) such as OpenMP. Xeon Phi launched in 2010. Since it was originally based on an earlier GPU design ( codenamed "Larrabee") by Intel that was cancelled in 2009, it shared application areas with GPUs. The main difference between Xeon Phi and a GPGPU like Nvidia Tesla was that Xeon Phi, with an x86-compatible core, could, with less modification, run software that was originally targeted to a standard x86 CPU. Initially in the form of PCIe-based add-on cards, a second-generation product, codenamed ''Knights Landing'', was announced in June 2013. These second-generation chips could be used as a standalone CPU, rather than just as an add-in card. In June 2013, the Tianhe-2 supercomputer at the National Supercomputer Center ...

Xenos (graphics Chip)
The Xenos is a custom graphics processing unit (GPU) designed by ATI (now taken over by AMD), used in the Xbox 360 video game console developed and produced for Microsoft. Developed under the codename "C1", it is in many ways related to the R520 architecture and therefore very similar to an ATI Radeon X1800 XT series of PC graphics cards as far as features and performance are concerned. However, the Xenos introduced new design ideas that were later adopted in the TeraScale microarchitecture, such as the unified shader architecture. The package contains two separate dies, the GPU and an eDRAM (manufactured by NEC), featuring a total of 337 million transistors. Specifications The chip is based on TeraScale microarchitecture, the shader units are organized in three SIMD groups with 16 processors per group, for a total of 48 processors. Each of these processors is composed of a 5-wide vector unit (total 5 FP32 ALUs), resulting in 240 units, that can serially execute up to two i ...

Application Programming Interface
An application programming interface (API) is a way for two or more computer programs to communicate with each other. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an ''API specification''. A computer system that meets this standard is said to ''implement'' or ''expose'' an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other. It is not intended to be used directly by a person (the end user) other than a computer programmer who is incorporating it into the software. An API is often made up of different parts which act as tools or services that are available to the programmer. A program or a programmer that uses one of these parts is said to ''call'' that ...

Ivy Bridge (microarchitecture)
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors (Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors, from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model. The name is also applied more broadly to the Xeon and Core i7 Ivy Bridge-E series of processors released in 2013. Ivy Bridge processors are backward compatible with the Sandy Bridge platform, but such systems might require a firmware update (vendor specific). In 2011, Intel released the 7-series Panther Point chipsets with integrated USB 3.0 and SATA 3.0 to complement Ivy Bridge. Volume production of Ivy Bridge chips began in the third quarter of 2011. Quad-core and dual-core-mobile models launched on April 29, 2012 and May 31, 2012 respectively. Core i3 desktop processors, as well as the first 22 nm Pentium, wer ...

Tianhe-2
Tianhe-2 or TH-2 (, i.e. 'Milky Way 2') is a 33.86-petaflops supercomputer located in the National Supercomputer Center in Guangzhou, China. It was developed by a team of 1,300 scientists and engineers. It was the world's fastest supercomputer according to the TOP500 lists for June 2013, November 2013, June 2014, November 2014, June 2015, and November 2015. The record was surpassed in June 2016 by the Sunway TaihuLight. In 2015, plans of the Sun Yat-sen University in collaboration with Guangzhou district and city administration to double its computing capacities were stopped by a U.S. government rejection of Intel's application for an export license for the CPUs and coprocessor boards. In response to the U.S. sanction, China introduced the Sunway TaihuLight supercomputer in 2016, which substantially outperforms the Tianhe-2 (and also affected the update of Tianhe-2 to Tianhe-2A replacing US tech), and now ranks fourth in the TOP500 list while using completely domestic technolog ...

PCIe
PCI Express (Peripheral Component Interconnect Express), officially abbreviated as PCIe or PCI-e, is a high-speed serial computer expansion bus standard, designed to replace the older PCI, PCI-X and AGP bus standards. It is the common motherboard interface for personal computers' graphics cards, hard disk drive host adapters, SSDs, Wi-Fi and Ethernet hardware connections. PCIe has numerous improvements over the older standards, including higher maximum system bus throughput, lower I/O pin count and smaller physical footprint, better performance scaling for bus devices, a more detailed error detection and reporting mechanism (Advanced Error Reporting, AER), and native hot-swap functionality. More recent revisions of the PCIe standard provide hardware support for I/O virtualization. The PCI Express electrical interface is measured by the number of simultaneous lanes. (A lane is a single send/receive line of data. The analogy is a highway with traffic in both directions.) T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nvidia Tesla
Nvidia Tesla was the name of Nvidia's line of products targeted at stream processing or general-purpose graphics processing units (GPGPU), named after pioneering electrical engineer Nikola Tesla.

GPGPU
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). The use of multiple video cards in one computer, or large numbers of graphics chips, further parallelizes the already parallel nature of graphics processing. Essentially, 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. While GPUs operate at lower frequencies, they typically have many times the number of cores. Thus, GPUs can process far more pictures and graphical data per second than a traditional CPU. Migrating data into graphical form and then using the GPU to scan and analyze it can create a large speedup. GPGPU pipelines were developed at the beginning of the 21st century for graphic ...

Reuters ( ) is a news agency owned by Thomson Reuters Corporation. It employs around 2,500 journalists and 600 photojournalists in about 200 locations worldwide. Reuters is one of the largest news agencies in the world. The agency was established in London in 1851 by the German-born Paul Reuter. It was acquired by the Thomson Corporation of Canada in 2008 and now makes up the media division of Thomson Reuters. History 19th century Paul Reuter worked at a book-publishing firm in Berlin and was involved in distributing radical pamphlets at the beginning of the Revolutions in 1848. These publications brought much attention to Reuter, who in 1850 developed a prototype news service in Aachen using homing pigeons and electric telegraphy from 1851 on, in order to transmit messages between Brussels and Aachen, in what today is Aachen's Reuters House. Reuter moved to London in 1851 and established a news wire agency at the London Royal Exchange. Headquartered in London, Reuter' ...
