The first autonomous CPU-based cloud computing system came out

SD-30 is the first set of China-based cloud computing processing and application system based on Godson-3B1500 processor developed by China Academy of Sciences Chen Guoliang, a member of the Academician of ShenZhen University, with the cooperation of Godson Technology Co., Ltd., which has high density, high energy efficiency and high scalability Features, the combination of hardware and software, virtual machine design and performance optimization and other key technologies reached the leading domestic level.

It is learned that the computational virtualization efficiency of SD-30 is considerable - SPECCPU2000 tests show that the computational virtualization efficiency of single, two, and four virtual machines on a single CPU node reaches more than 80%. The Stream Memory Bandwidth Test The results show that the single-node, two-node and four-node virtual machines have more than 85% storage virtualization efficiency.

Cai Ye, deputy director of the Center for High Performance, Shenzhen University, said: "Autonomous CPU to do to support the cloud platform, the main difficulty in the virtualization technology, the physical resources into logical resources for easy scheduling management.Virtualization can be divided into two aspects to understand, First, the positive virtualization - a number of physical nodes to form a logical node, Hadoop, cloud storage These Internet applications actually need this. Second is the reverse virtualization - the physical node is divided into a number of logical nodes , And really need to support the CPU level is mainly reverse virtualization, the other is the work of the software ... In order to achieve Godson 3B1500 cloud platform support, Shenzhen University and Godson use a combination of hardware and software, the operating system kernel to do Certainly, the virtualization system HKVM-Loongson based on the domestic Loongson CPU has finally been implemented on the SD-30. The system uses KVM virtualization technology and the OpenStack open source cloud computing software stack, and is built for the first time on more than 40 domestic Loongson clustered servers Massively virtualize nodes and implement effective resource management and scheduling of more than 300 cloud computing virtual nodes.

Single Shaft Hammer Mill

Compared with other crushers, the single shaft crusher has a larger crushing chamber. Widely used in wood chips, straw, straw and other fiber materials crushing.

The motor and rotor are installed in the same heavy-duty base, using coupling direct drive, rotor passes accurate dynamic balancing test, the hammers are arranged symmetrically.
Unique Feeding Design, the feeding inlet is made on the top of the machine to make feeding easily.
The shell is welded by steel plate, the site in the crush room which connects to the materials all use the wearable and commutative parts and double wear plate.
Hammers adopts special abrasion resistent treatment technology, extend its lifetime greatly.
