NEC SX-ACE
The SX-ACE is a vector NEC SX supercomputer from NEC Corporation. It features NEC's first multi-core vector System on a Chip design, with four cores. The SX-ACE runs at 1 GHz, has peak performance of 64 GFLOPS per core, and has 64 gigabytes per second of memory bandwidth per core. Four cores make up a shared-memory node, and 64 nodes can fit in a rack for a total performance of 16 TFLOPS per rack. The SX-ACE was released in 2013. NEC released the successor, the SX-Aurora TSUBASA in 2017."Roadmap" image iNEC SX-ACE Photos/ref> It is used by Earth Simulator 3.

NEC SX
is a Japanese multinational information technology and electronics corporation, headquartered in Minato, Tokyo. The company was known as the Nippon Electric Company, Limited, before rebranding in 1983 as NEC. It provides IT and network solutions, including cloud computing, artificial intelligence (AI), Internet of things (IoT) platform, and telecommunications equipment and software to business enterprises, communications services providers and to government agencies, and has also been the biggest PC vendor in Japan since the 1980s when it launched the PC-8000 series. NEC was the world's fourth-largest PC manufacturer by 1990. Its semiconductors business unit was the world's largest semiconductor company by annual revenue from 1985 to 1992, the second largest in 1995, one of the top three in 2000, and one of the top 10 in 2006. NEC spun off its semiconductor business to Renesas Electronics and Elpida Memory. Once Japan's major electronics company, NEC has largely withdrawn from ...

Vector Processor
In computing, a vector processor or array processor is a central processing unit (CPU) that implements an instruction set where its instructions are designed to operate efficiently and effectively on large one-dimensional arrays of data called ''vectors''. This is in contrast to scalar processors, whose instructions operate on single data items only, and in contrast to some of those same scalar processors having additional single instruction, multiple data (SIMD) or SWAR Arithmetic Units. Vector processors can greatly improve performance on certain workloads, notably numerical simulation and similar tasks. Vector processing techniques also operate in video-game console hardware and in graphics accelerators. Vector machines appeared in the early 1970s and dominated supercomputer design through the 1970s into the 1990s, notably the various Cray platforms. The rapid fall in the price-to-performance ratio of conventional microprocessor designs led to a decline in vector supercom ...

System On A Chip
A system on a chip or system-on-chip (SoC ; pl. ''SoCs'' ) is an integrated circuit that integrates most or all components of a computer or other electronic system. These components almost always include a central processing unit (CPU), memory interfaces, on-chip input/output devices, input/output interfaces, and secondary storage interfaces, often alongside other components such as radio modems and a graphics processing unit (GPU) – all on a single substrate or microchip. It may contain digital, analog, mixed-signal, and often radio frequency signal processing functions (otherwise it is considered only an application processor). Higher-performance SoCs are often paired with dedicated and physically separate memory and secondary storage (such as LPDDR and eUFS or eMMC, respectively) chips, that may be layered on top of the SoC in what's known as a package on package (PoP) configuration, or be placed close to the SoC. Additionally, SoCs may use separate wireless modems. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NEC SX-Aurora TSUBASA
The NEC SX-Aurora TSUBASA is a vector processor of the NEC SX architecture family. Unlike previous SX supercomputers, the SX-Aurora TSUBASA is provided as a PCIe card, termed by NEC as a "Vector Engine" (VE). Eight VE cards can be inserted into a vector host (VH) which is typically a x86-64 server running the Linux operating system. The product has been announced in a press release on 25 October 2017 and NEC has started selling it in February 2018. The product succeeds the SX-ACE. Hardware SX-Aurora TSUBASA is a successor to NEC SX, the NEC SX series and SUPER-UX, which are vector computer systems upon which the Earth Simulator supercomputer is based. Its hardware consists of Linux, x86 Linux hosts with vector engines (VEs) connected via PCI Express, PCI express (PCIe) interconnect. High memory bandwidth (0.75–1.2 TB/s), comes from eight cores and six HBM2 memory modules on a silicon interposer implemented in the form-factor of a PCIe card.

Earth Simulator
The is a series of supercomputers deployed at Japan Agency for Marine-Earth Science and Technology Yokohama Institute of Earth Sciences. Earth Simulator (first generation) The first generation of Earth Simulator, developed by the Japanese government's initiative "Earth Simulator Project", was a highly parallel vector supercomputer system for running global climate models to evaluate the effects of global warming and problems in solid earth geophysics. The system was developed for Japan Aerospace Exploration Agency, Japan Atomic Energy Research Institute, and Japan Marine Science and Technology Center (JAMSTEC) in 1997. Construction started in October 1999, and the site officially opened on 11 March 2002. The project cost 60 billion yen. Built by NEC, ES was based on their SX-6 architecture. It consisted of 640 nodes with eight vector processors and 16 gigabytes of computer memory at each node, for a total of 5120 processors and 10 terabytes of memory. Two nodes were inst ...

SUPER-UX
SUPER-UX is a version of the Unix operating system from NEC that is used on its SX series of supercomputers. History The initial version of SUPER-UX was based on UNIX System V version 3.1 with features from BSD 4.3. The version for the NEC SX-9 was based on SVR4.2MP with BSD enhancements. Features SUPER-UX is a 64-bit UNIX operating system. It supports the Supercomputer File System (SFS). Earth Simulator The Earth Simulator uses a custom OS called "ESOS" (Earth Simulator Operating System) based on SUPER-UX. It has many enhanced features custom designed for the Earth Simulator which are not in the regular SUPER-UX OS. See also * EWS-UX EWS-UX is a Unix operating system used by NEC Corporation for its EWS-4800 line of engineering workstations. EWS-UX is based largely on versions of Unix System V supplemented with BSD software. It was widely used from the late 1980s to around 2 ...
