Recently, great news has emerged from the National Supercomputing Shenzhen Center Phase II Project. LingSheng, a fully domestically-developed supercomputer deployed in the project, has sustained computing performance exceeding 2 ExaFLOPS, reclaiming the world’s No.1 ranking.
Faced with the enormous energy consumption challenge brought by exascale computing power, drawing on profound research expertise and cutting-edge design concepts, China IPPR has built the world’s largest centralized liquid cooling system, reconstructing the computing infrastructure with exceptional energy efficiency.
Centered on intelligent integrated computing, the LingSheng supercomputer system fully supports exascale computing power, exascale storage and petascale communication. It connects computing power, algorithms and application transformation channels, covers benchmark applications across various fields, and forms a replicable and promotable implementation model for domestic computing power. It serves as a vital platform underpinning national strategies and fueling industrial innovation in the Greater Bay Area.
Following its design work for Phase I of the supercomputing center, China IPPR continued to deliver services for this major science and technology facility — National Supercomputing Shenzhen Center Phase II. The project adopts 14 circuits of 20kV power distribution, and creates an efficient and reliable power core for the 2 ExaFLOPS supercomputer through high-voltage direct current and full-link redundancy. Leveraging core full-liquid cooling heat dissipation technology, the world’s largest centralized liquid cooling system has been constructed.
A centralized CDU architecture is adopted to address the difficulty of CDU arrangement caused by ultra-high power per cabinet, delivering outstanding liquid cooling performance. The total length of secondary pipelines reaches 3,214.7 meters, and the net weight of the system stands at 243.9 tons.
A high-load high-temperature liquid cooling system is established. The cross-sectional diameter of primary and secondary main loop pipes in the high-temperature system reaches 1,200 mm; the electric power of the system’s circulating water pump hits 315 kW, the total cooling capacity of the high-temperature liquid cooling system is 57,900 kW, and the heat exchange capacity of a single plate heat exchanger peaks at 8,700 kW.
The elaborately designed liquid cooling circulation architecture enables efficient heat dissipation for high-density computing equipment and keeps the Power Usage Effectiveness (PUE) at an ultra-low level.
Deeply aligned with national strategic planning, China IPPR drives design upgrades via scientific and technological innovation and maintains an industry-leading position in data center design and consultation. Centered on tackling cutting-edge technologies including liquid cooling and pre-project technical comparison and selection, the company lowers PUE through technological innovation and improves energy conversion efficiency. It facilitates the implementation of ultra-large-scale domestic supercomputing and intelligent computing systems, and provides clients with reliable, green and efficient modern data center solutions.
Looking ahead to the 15th Five-Year Plan period, China IPPR will continuously strengthen scientific and technological innovation capacity, deeply participate in the implementation of the East Data, West Computing project, support the construction of national digital infrastructure, and contribute Chinese wisdom and Chinese solutions to the global transition of data centers toward high efficiency and low carbon emissions.
