the face of severe challenges, aiming at the international forefront,
to seize the technological high ground
today's world, high-performance computing has become the third addition to theoretical and experimental scientific instruments, is to promote technological innovation and high-tech economic and social development strategy. November 2007, the United States developed the world's first petaflop supercomputer, the peak computing speed per 1,456,000,000,000,mac makeup wholesale,000 times. Published in June 2009 the world's top 500 supercomputers (TOP500), the United States accounted for 291 seats, 145 seats occupied Europe, and the top 10 are American products. Compared with developed countries,mac brushes, China not only in an order of magnitude difference in computing power, a far cry from the number of installed capacity.
in a rapidly changing and highly competitive field of supercomputer research, fall behind is very real and cruel rules of survival. The face of high performance computing challenges, National Defense Science and Computer Science, the researchers had to climb once again sounded the peak of world science and technology Chong Fenghao - aimed at the international forefront of implementation of the advance deployment, enhance technology accumulation and advance research, and actively seize strategic high ground for the early development of the China's petaflop supercomputer.
this was the Central Military Commission awarded the China's supercomputer But they clearly know that to change from one hundred trillion times to the petaflop leap, innovation and progress than any previous one to be much more difficult.
hospital development of high performance computing in accordance with international trends and latest developments, organizations, experts and professors in-depth feasibility studies, established a national and military strategic needs as the drive to the original innovation and integrated innovation combine to achieve innovation ability of the overall jump in the development of ideas. They organized and capable technology for the development of cutting-edge high-performance computing technology, key technology and emerging technology areas such as cross-basic research and frontier exploration, have been a massive breakthrough in scalable shared memory architecture and a series of technical problems,mac makeup, master a number of key technologies with independent intellectual property rights for the development of more high-performance supercomputers lay the technology foundation.
opportunities always favor those who are prepared. When China will develop a petaflop supercomputer systems included in the
teamwork research, adhere to independent innovation,
breakthrough in key technologies
the development of the world's supercomputers that each increase of one order of magnitude of computing power, we need system the structure of a series of key innovations and technological breakthroughs.
supercomputer developed as China's important base for National Defense Science and Computer Science, while having strong technical accumulation and wealth of engineering experience, but from a one hundred trillion times to the petaflop the technological leap, is also a lot of difficulties. Face many technical problems and challenges, the researchers developed a supercomputer in summing up the past on the basis of experience, work together to set intellectual research, adhere to independent innovation, and strive to overcome the core and key technologies, high performance computing in China push forward the cause.
petaflop supercomputer in the architecture design, they creatively put forward the multi-array, configurable, collaborative parallel architecture, by implementing speed processors) After a long closure of their research and iteration, the GPU computational efficiency in one fell swoop from the international community usually 20% to 70%, the system operation speed to be increased dramatically.
to meet the various users of supercomputers openness and security requirements,vibram 5 fingers, the researchers developed a national high B2-level security standard operating system and software security through isolation and Virtual Domains, each structure isolation of the user independent work environment, effective implementation of the open network environment, the security of confidential information under the user isolation. Multiple users to share
system fault tolerance is to evaluate an important indicator of a super computer system. Researchers in the They also established a multi-layer fault-tolerant technology, through the checkpoint function of the operating system, resource management, task-level and operational-level fault tolerance, and fault-tolerant parallel algorithms and breakpoint count functions, improve system reliability.
with a series of breakthroughs in key technology and engineering to achieve, Application advantages.
