### 项目描述 | ||
|
||
...... | ||
内存页更新算法一直是操作系统的热门话题,在现代计算机内存的飞速增长,和更多的速度/大小分级下,页分配与回收, 页管理的算法,工作集的判断与处理都有继续探讨的必要。 Linux内核也在这个领域不断进化, 但是仍然有一些可以继续探索的机会。 | ||
|
||
题目1, | ||
Linux 内核使用lru 来管理页,目前系统内存5个lru lists 还在共享一把锁来管理,这造成了不必要的锁冲突,是否可以对不同的lru list使用不同的锁来管理,来降低锁冲突,提高页使用的性能。 | ||
|
||
题目 2, | ||
Linux 内核使用lru 算法来管理页,lru本身的特点使其并不合适超大的页管理, 对于媒体播放,垃圾收集和其他大地址范围的应用并不合适。 尝试使用现代页管理算法 CAR Clock with Adaptive Replacement在内核中代替LRU算法,并比较与LRU 算法的优劣。 | ||
