多线程多核服务器功耗模型及性能监控

Power Consumption Model and Performance Monitoring of Multi-threaded and Multi-core Servers

针对现有服务器的CPU功耗准确性不足和多线程处理功耗负载不平衡问题,本文提出了一种多线程和多核服务器CPU功耗模型。该模型采用前后端分离的整体架构思想,根据服务器功耗模型实时获取CPU的线程数、频率及利用率。通过日志文件进行反馈多线程和多核功耗模型,达到最佳服务器负载平衡。仿真测试的结果表明,改进的服务器功耗模型在CPU利用率方面比传统服务器提高了6%,内存以及I/O通信方面也有明显改善,为多线程和多核服务器提供了一种新的功耗模型思路。

This paper proposes a multi threaded and multi-core server CPU power consumption model to address the issues of insufficient accuracy in CPU power consumption and load imbalance in multi threaded processing of existing servers.The model adopts the overall architecture concept of front-end and back-end separation,and real-time obtains the number,frequency,and utilization of CPU threads based on the server power consumption model.Provide feedback on multi-threaded and multi-core power consumption models through log files to achieve optimal server load balancing.The simulation test results show that the improved server power consumption model has increased CPU utilization by 6%compared to traditional servers,and there is also a significant improvement in memory and I/O communication.This model provides a new power consumption model approach for multi-threaded and multi-core servers.
