The present application discloses a system for controlling power supply redundancy of GPU server, including power supply redundancy module which includes first and second PSU, BMC, CPLD and GPU module which includes plurality of GPUs. The first PSU is connected to the CPLD by first bus, and the second PSU is connected to the CPLD by second bus. The BMC is connected to the CPLD by first I2C bus and second I2C bus, and sends heartbeat information to the CPLD. The CPLD is connected to the BMC by third bus and fourth bus, and the CPLD is connected to the several GPUs by third I2C bus. When the BMC is abnormal or restarted, the CPLD may control the overall power consumption of the server, it may be ensured that the server will not crash, and the loss of users caused by the BMC being abnormal or restarted will be reduced.

Power supply redundancy control system and method for GPU server and medium

The disclosure relates to the technical field of building materials, and in particular, to lightweight aggregate ultra-high performance concrete (UHPC) and a preparation method thereof. The lightweight aggregate UHPC provided in the disclosure is prepared from the following components in parts by weight: cement 220-260 parts; silica fume 100-120 parts; expanded perlite powder 120-160 parts; expanded perlite 230-260 parts; polycarboxylate superplasticizer 15-20 parts; steel fiber 76-93 parts; and water 140-160 parts, where a maximum particle size of the expanded perlite powder is 0.075 mm; and a particle size range of the expanded perlite is 0.075-0.6 mm. The lightweight UHPC prepared according to the design of the disclosure has excellent density performance, and can satisfy requirements of concrete components, etc. in service in super-long-span bridges, super high-rise buildings, and complex marine environments for lightweight, ultra-high strength, and ultra-high durability of cement-based materials, and has a relatively high promotion value.
