wipe-v2's Introduction

Project WIPE v2

WIPE v2 simulator

设计目标

本计划旨在通过制作自动化程序,来优化interactive,HMP,inputboost参数: This project aims to optimize the parameters of interactive, HMP, and inputboost by creating automated programs:

  • 现实负载采集(real world workload capture)
  • interactive调速器流程仿真(interactive governor process simulation)
  • 卡顿和耗电评分函数(cost function of lag and power comsuption)
  • 迭代取得局部最优(iteration to obtain local optimum)

相比Project WIPE v1

  1. 支持WALT HMP参数模拟
  2. 支持input boost参数模拟
  3. 全频率档位支持及可变参数序列长度
  4. 毫秒级的负载序列和渲染的性能需求,来自systrace
  5. 改进的续航和性能评分函数
  6. 启发式优化算法使用NSGA-III
  7. 同样的任务量和硬件条件下,优化执行效率提升~450%

如何使用

  1. 编译发布版本make release
  2. 修改配置文件./conf.json,选择要做优化的CPU模型列表,以及使用的负载序列和参数范围
  3. 执行mkdir output创建输出文件夹
  4. 执行./wipe,会自动加载./conf.json,并按照列表顺序依次执行优化
  5. output输出文件夹,根据你的流畅度和耗电的要求,在候选中寻找合适的参数组合
  6. 本项目在GCC 7.3测试通过
