1. Introduction of FPGA,GPU and CPU in High performance Computing in recent years, GPU, which is traditionally used in image processing, has been gradually discovered for high performance computing, and has achieved quite good results. The speed is as fast as 5TFLOPs in single-precision floating-point operations and in double-precision floating-point operations.
The sudden failure of the data center (such as the inevitable disaster of natural disasters) is unpredictable. The data in the computer is like a minesweeping game. It is full of minefields and may be Game Over at any time. Disaster recovery backup is the last line of defense of data security, but you can avoid being sent by the data center.
