Description

technical field [0001] The invention belongs to the field of computer cloud service system testing, and more specifically relates to a method and system for testing the performance of an FPGA cloud server. Background technique [0002] Programmable gate array (FPGA) has been widely used in technical fields such as machine learning and high-performance scientific computing due to its high throughput and low latency. With the development of cloud service technology, FPGA cloud servers have gradually become popular. FPGA As a coprocessor of the CPU, it is used to accelerate various cloud services. The FPGA cloud server overcomes the disadvantages of difficult FPGA programming, and at the same time effectively utilizes the powerful computing power and reprogrammable features of FPGA. Users only need a terminal device and a network connection to obtain computing power dozens or even several times higher than that of CPU. Hundred times the computing resources and software resourc...

AI Technical Summary

Problems solved by technology

Compared with the physical environment, the cloud environment is more complex, and the simplification of the programming interface also conceals many design details, so the performance test of the FPGA cloud server is a very difficult task

The current cloud server performance testing methods mainly consider all aspects of virtual machine performance, including CPU computing power, memory, network, and hard disk, etc. However, these testing methods do not take into account the underlying physical structure of the FPGA cloud server architecture The impact on the performance of the FPGA cloud server, therefore, the test results obtained through the existing FPGA cloud server performance test methods cannot reflect the real performance of the FPGA cloud server

Therefore, the existing FPGA cloud service performance testing methods are not very accurate
