闪存调度算法？ [英] Flash memory scheduling algorithms?

问题描述

我想做围绕文件系统的一些研究，我可能混淆自己。我得磁盘调度算法与盘如扫描和CSCAN设备，但我想知道的当量是什么闪存？

I'm trying to do some research around file systems and I've probably confused myself. I've got to disk scheduling algorithms for devices with discs such as SCAN and CSCAN, but I was wondering what the equivalents are for flash memory?

推荐答案

有一些研究方法，如在的 2009年的论文一种新的I / O调度固态设备。 不过，我不知道任何这是在实践中使用。的空操作的调度，这意味着该调度程序没有重新排序的请求，似乎是标准调度用于SSD的

There are some research approaches like in the 2009 paper "A New I/O Scheduler for Solid State Devices". However, I am not aware that any of this is used in practice. The "Noop" scheduler, which means that the scheduler is not reordering requests, seems to be the standard scheduler to use for SSDs.

总之，有很多更应该在今天OS改变，真正具有现代和未来固态硬盘进行中的这个MSST 2010纸。

Anyway, a lot more should change in todays OS to really perform with modern and future SSDs as pointed out in this MSST 2010 paper.
