A.Compute nodes only provide computing resources such as CPU and memory. The hardware configuration information is stored in the configuration file, and the data is stored centrally on the disk array, which realizes the independence of network, storage and computing nodes.

B.Stateless computing technology eliminates the dependence on the virtualization layer Hypervisor, so the database can use hardware-based stateless computing technology to achieve low-cost high-availability solutions.

C.The configuration of computing nodes is saved in the chassis management module, which can be imported and exported. The active and standby chassis management modules are automatically synchronized, and the active and standby backups are mutually backup. When the management module is switched over, the configuration strategy will not be affected.

A.Installation and commissioning

B.Project watchdog

C.Distributed storage system writes data: According to the LBA of the application layer and the block size, multiple keys are generated in units of 1MB, and the keys are hashed into a patation ID, and then the main OSD is found according to the partition ID, and the main OSD notifies the backup corresponding to the partition OSD write data.

D.Planning and design

E.Project acceptance

A.Business application layer software

B.Database software

C.Middleware

D.Application software

A.Single system runs independently and efficiently.

B.Realize intelligent scheduling and optimization.

C.Resource decoupling

D.Dynamic resource allocation

A.Currently popular heterogeneous programming frameworks in the industry are: OpenCL, CUDA, C++AMP

B.Moore's Law is blocked, and the surge in data is the cause of heterogeneous computing.

C.Common computing unit categories include CPU, GPU, DSP, ASC, FPGA, etc.

D.Common heterogeneous system architectures are: CPU+GPU, GPU+FPGA, CPU+ special chip
