论文摘要
多插入多核服务器用于求解计算中的一些重要问题。远程DRAM访问会影响在此类服务器上运行的某些应用程序的性能。本文介绍了一种新的近线性操作系统（OS）调度算法，以减少此类远程DRAM访问的影响。通过跟踪使用性能计数器，每个线程并应用此算法的本地和远程DRAM访问的数量，我为下一个量子提出了新的线程时间表。这个新的时间表可减少远程DRAM访问并提高整体性能。我还表明，在最好的情况下，该算法实际上是线性的。由于该算法是接近线性的，因此可以在实际操作系统中实现。
Multi-socket multi-core servers are used for solving some of the important problems in computing. Remote DRAM accesses can impact performance of certain applications running on such servers. This paper presents a new near linear operating system (OS) scheduling algorithm to reduce the impact of such remote DRAM accesses. By keeping track of the number of local and remote DRAM accesses, using performance counters, for every thread and applying this algorithm, I come up with a new schedule of threads for the next quantum. This new schedule reduces remote DRAM accesses and improves overall performance. I also show that this algorithm is actually linear in the best case. As the algorithm is near-linear it is amenable for implementation in a real operating system.
