以负载均衡和数据缓存为例谈操作系统启发式教学

针对在传统操作系统教学中存在灌输知识的状况和计算机多处理器并发带来的影响,从多核环境下的简单问题出发,在分析操作系统多核环境下进程调度的基础上,提出如何完美实现负载均衡机制。通过增加Cache数量和容量增加数据命中率,提升系统性能,结合学生学习新课程知识的实际,以启发式案例教学的方式系统分析操作系统在多核环境下的进程调度问题,使学生从一个简单问题入手逐渐掌握较深入的知识。

Discussion on Heuristic Teaching in Operating System Taking Load Balance and Data Cache as Examples

Since there exist many cases of irrigating knowledge in traditional teaching in operating system and impacts of multi-core environments in computers,based on the analysis of process scheduling in multi-cores environments,starts from simple questions under multi-core situation and promotes the system performance by proposing mechanisms of load balance and increasing numbers and capacities of cache to improve data hit rate.Connecting real problems with students’ learning new knowledge,analyzes the process scheduling of OS in multi-cores environments in a fashion of heuristic teaching case and leads students from simple questions to a deep phase.
