"Tianhe-2" supercomputer system is the world's fastest supercomputer developed by National University of Defense Technology at a cost of about 100 million US dollars. It is a key project of the National 863 Program. The structural design, ID design and thermal design of "Tianhe-2" are all independently developed by our company. Tianhe-2, with 170 cabinets, covers almost the same area as Tianhe-1, but has 11.6 times the performance. Compared with the Titan system of the United States, which ranked first in the world, the system occupies 85 percent of its area and has twice the performance. The structure design realizes the high density and high precision assembly structure based on front and rear insertion and horizontal blind insertion of the backplane. The calculated density of Tianhe-2 is at the leading international level... Take high density and high precision structure process as an example, In terms of architecture, microheterogeneous computing array framework, system fault tolerant array, high-speed interconnection network, accelerated storage architecture, parallel programming model and framework, system fault tolerant array, high-speed interconnection network, accelerated storage architecture, parallel programming model and framework, system fault tolerant array, high-speed interconnection network, accelerated storage architecture, parallel programming model and framework, system fault tolerant array, high-speed interconnection network, accelerated storage loss control technology and high density and high precision structure technology, etc., A number of core and key technologies have been broken through."
