Server architecture, database query method thereof and storage medium

Abstract

The invention provides a server architecture, and the server architecture comprises: a processor; and a database acceleration chip which is connected with the processor through a high-speed serial interface. The database acceleration chip and the processor are in a heterogeneous working mode, and the database acceleration chip is used for bearing database retrieval tasks. According to the method,the manner that a current hardware platform takes the processor as a single core is converted into that manner that the current hardware platform takes the processor and the database acceleration chipas double cores, and when the database retrieval task is received, the processor transfers the retrieval task to the database acceleration chip for processing, so that the use of other functions of the server is not influenced. The database acceleration chip is specially used for executing the database retrieval task, so that the process of transferring the data packet from the processor is reduced, the data communication delay is reduced, and the database detection efficiency is improved. The invention further provides a database query method and a computer readable storage medium, which have the above beneficial effects.

AI Technical Summary

Problems solved by technology

[0002] In the existing solution, the data communication between the processor and the accelerator is performed through the traditional PCIe protocol. Due to the limitation of the PCIe protocol, the delay of data transmission in this way is very large, which seriously restricts the performance.

[0003] The main reason is that this traditional communication method needs to map the accelerator-side address space to the processor-side memory address space, convert virtual and real addresses, and also need to go through complex driver software, which has a large delay; secondly, the existing architecture is based on processing As a computing center, the processor accesses the memory space of the accelerator through the PCIe controller, the processor load is high, and the storage efficiency is low; in addition, the existing database query acceleration logic has low performance in terms of algorithm, operating frequency, parallelism, etc., which affects The overall acceleration performance of the system
