10 月 22 日至 24 日,由教育部学位管理与研究生教育司指导、中国学位与研究生教育学会和中国科协青少年科技中心主办、国防科技大学承办的 “松山湖杯”第一届中国研究生操作系统开源创新大赛决赛在长沙落幕。 | ||
|
||
经激烈角逐,SOLE 实验室两支参赛队伍“zoltraak_队”与“爱吃泡芙队”,分别斩获全国二等奖与全国三等奖,参赛队伍指导教师郭健美教授获“优秀指导教师奖”! | ||

### 全国二等奖 | 基于ebpf的容器异常检测平台 | ||
|
||
“zoltraak_队”:程奂仑,徐静,何海林 | ||
|
||
本项目完成了一个基于eBPF(extened Berkeley Packet Filter)的性能采集框架,并对容器间CPU资源竞争、内存溢出、锁竞争等异常事件进行检测。本项目定义了“context switch out”指标及其采集方法,使用图论方法定位容器间资源竞争。对锁资源的竞争使用阈值方法定位Futex瓶颈进程,对OOM 事件则利用内核信息完成根因诊断。指标采集上,对CPU利用率进行容器级别的拆解,为异常定位提供细致的指标数据。 | ||
|
||
### 全国三等奖 | 基于龙蜥操作系统的应用性能监测与预测软件 | ||
|
||
“爱吃泡芙队”:刘通宇,李宁,廖浩宇 | ||
|
||
软硬件全栈的性能数据监控对数据中心的资源隔离、应用调度与性能预测具有重要意义。本项目实现了一个跨平台的软硬件全栈的性能监测与预测工具 hperf,该工具针对现有工测量的低效行为,通过研究 Linux 内核性能事件的调度机制,提出一种自适应的性能事件分组方法提高性能计数器的复用效率,以实现数据的高效采集。此外,本工具还基于 sar 实现了软件性能数据监控,并基于主流时间序列预测算法实现了性能预测。本工具支持 x86 与 aarch64 主流服务器处理器的性能监控,相较于当前主流工具,在测量效率上约有 50% 的提高,并且测量准确率达到商用工具水平。 | ||
