Buffer Cache

Buffer Cache

Now that we’ve seen how file systems work, we turn to several optimizations that help make it fast, since most storage devices tend to be slow. We’ll first discuss some software optimizations and then turn to hardware. If you’re first reaction is, let’s use a cache, then you’re on the right track. Indeed most operating […]

Cache Affinity and Multicore – Georgia Tech – Advanced Operating Systems

So let’s talk about cache affinity and modern multicore processors, in modern multicore processors you have multiple cores on a single processor, and in addition to the multiple cores that are in a single processor, the processors the,selves are also hardware multithreaded. What hardware multithreading means is that. If a, if a thread that is […]

Why do CPUs Need Caches? – Computerphile

So, I’ve come here today because you promised me “cache”, but I don’t see any money. I thought you were paying me for these things, but- No, we’re not talking about that sort of cash. We’re actually looking for the cache that is built into our CPUs and they’re used in computers to try and […]

Cache Aware Scheduling – Georgia Tech – Advanced Operating Systems

So let me briefly introduce here the idea of cache aware scheduling, when you have these multithreaded multi-core processors. And to make things concrete, let’s assume that you have a pool of ready threads, and in this case I’m going to tell you that the pool of ready threads I have is 32. So I […]

Rio File Cache – Georgia Tech – Advanced Operating Systems

Before we talk about how we can implement RVM efficiently with a back to back DRAM. Let’s first understand how we can use a back to back to DRAM to implement a persistent file cache. What we mean by that is, typically file systems use a file cache to hold data that is brought from […]
