Tianhe-IA
Tianhe-I, Tianhe-1, or TH-1 (, ; '' Sky River Number One'') is a supercomputer capable of an Rmax (maximum range) of 2.5 peta FLOPS. Located at the National Supercomputing Center of Tianjin, China, it was the fastest computer in the world from October 2010 to June 2011 and was one of the few petascale supercomputers in the world. In October 2010, an upgraded version of the machine (Tianhe-1A) overtook ORNL's Jaguar to become the world's fastest supercomputer, with a peak computing rate of 2.57 petaFLOPS. In June 2011 the Tianhe-1A was overtaken by the K computer as the world's fastest supercomputer, which was also subsequently superseded. Both the original Tianhe-1 and Tianhe-1A use a Linux-based operating system. On 12 August 2015, Tianhe-1 felt the impact of the powerful Tianjin explosions and went offline for some time. Xinhua reports that "the office building of Chinese supercomputer Tianhe-1, one of the world's fastest supercomputers, suffered damage". Sources at Tianhe ...

Tianhe (space Station Module)
''Tianhe'' (), officially the ''Tianhe'' core module (), is the first module to launch of the Tiangong space station. It was launched into orbit on 29 April 2021, as the first launch of the final phase of Tiangong program, part of the China Manned Space Program (Project 921). ''Tianhe'' follows the earlier projects Salyut, Skylab, Mir, International Space Station, Tiangong-1 and Tiangong-2 space stations. It is the first module of a third-generation Chinese modular space station. Other examples of modular station projects include the Soviet/Russian Mir and the International Space Station. Operations will be controlled from the Beijing Aerospace Flight Control Center. In 2018, a fullscale mockup of ''Tianhe'' was publicly presented at China International Aviation & Aerospace Exhibition in Zhuhai.

Jaguar (supercomputer)
Jaguar or OLCF-2 was a petascale supercomputer built by Cray at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. The massively parallel Jaguar had a peak performance of just over 1,750 teraFLOPS (1.75 petaFLOPS). It had 224,256 x86-based AMD Opteron processor cores, and operated with a version of Linux called the Cray Linux Environment. Jaguar was a Cray XT5 system, a development from the Cray XT4 supercomputer. In both November 2009 and June 2010, TOP500, the semiannual list of the world's top 500 supercomputers, named Jaguar as the world's fastest computer. In late October 2010, the BBC reported that the Chinese supercomputer Tianhe-1A had taken over the top spot, achieving over 2.5 quadrillion calculations per second, thereby bumping Jaguar to second place. The November 2010 TOP500 list confirmed the new rankings. In 2012, the Cray XT5 Jaguar was upgraded to the ''Cray XK7 Titan'' hybrid supercomputing system by adding the Gemini network interconnect and fit ...

Advanced Micro Devices
Advanced Micro Devices, Inc. (AMD) is an American multinational semiconductor company based in Santa Clara, California, that develops computer processors and related technologies for business and consumer markets. While it initially manufactured its own processors, the company later outsourced its manufacturing, a practice known as going fabless, after GlobalFoundries was spun off in 2009. AMD's main products include microprocessors, motherboard chipsets, embedded processors, graphics processors, and FPGAs for servers, workstations, personal computers, and embedded system applications. History First twelve years Advanced Micro Devices was formally incorporated by Jerry Sanders, along with seven of his colleagues from Fairchild Semiconductor, on May 1, 1969. Sanders, an electrical engineer who was the director of marketing at Fairchild, had, like many Fairchild executives, grown frustrated with the increasing lack of support, opportunity, and flexibility within th ...

Supercomputing Conference
SC (formerly Supercomputing), the International Conference for High Performance Computing, Networking, Storage and Analysis, is the annual conference established in 1988 by the Association for Computing Machinery and the IEEE Computer Society. In 2019, about 13,950 people participated overall. The not-for-profit conference is run by a committee of approximately 600 volunteers who spend roughly three years organizing each conference. Sponsorship and Governance SC is sponsored by the Association for Computing Machinery and the IEEE Computer Society. From its formation through 2011, ACM sponsorship was managed through ACM's Special Interest Group on Computer Architecture (SIGARCH). Sponsors are listed on each proceedings page in the ACM DL; see for example. Beginning in 2012, ACM began the process of transitioning sponsorship from SIGARCH to the recently formed Special Interest Group on High Performance Computing (SIGHPC). This transition was completed after SC15, and for SC16 ACM ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TOP500
The TOP500 project ranks and details the 500 most powerful non-distributed computing, distributed computer systems in the world. The project was started in 1993 and publishes an updated list of the supercomputers twice a year. The first of these updates always coincides with the International Supercomputing Conference in June, and the second is presented at the ACM/IEEE Supercomputing Conference in November. The project aims to provide a reliable basis for tracking and detecting trends in high-performance computing and bases rankings on HPL (benchmark), HPL, a portable implementation of the high-performance LINPACK Benchmark (computing), benchmark written in Fortran for distributed-memory computers. The 60th TOP500 was published in November 2022. Since June 2022, USA's Frontier (supercomputer), Frontier is the most powerful supercomputer on TOP500, reaching 1102 petaFlops (1.102 exaFlops) on the LINPACK benchmarks.

2015 Tianjin Explosions
On 12 August 2015, a series of explosions at the Port of Tianjin in Tianjin, northern China, killed 173 people, according to official reports, and injured hundreds of others. The explosions occurred at a container storage station in the Binhai New Area of Tianjin, China. The first two explosions occurred 33 seconds apart. The second explosion was far larger and involved the detonation of about 800 tonnes of ammonium nitrate (approx. 256 tonnes TNT equivalent). Fires caused by the initial explosions continued to burn uncontrolled throughout the weekend, resulting in eight additional explosions on 15 August. The cause of the explosions was not immediately known, but an investigation concluded in February 2016 that an overheated container of dry nitrocellulose was the cause of the initial explosion. The official casualty report was 173 deaths, 8 missing, and 798 non-fatal injuries. Of the 173 fatalities, 104 were firefighters. Background Tianjin Dongjiang Port Ruihai Internati ...
