Handling stack overflow on custom stacks
+0 Vote Up -0Vote Down

On my computer, the callstack of a new process is around 10MB*. Modern operating system automatically reserve some amount of virtual memory and install protections on the page below the stack to create a segmentation fault on stack overflow. This ensures that a stack overflow won’t go corrupting random parts of memory.

We want to have a lot of coroutines, so they should have smaller stacks, maybe 16 or 64KB. This makes stack overflow an even greater possibility, but at the same time, coroutines implemented in user space don’t get this checking for free—we have to build it ourselves. In the process, we can even do better: we can give …

Making coroutines fast
+2 Vote Up -0Vote Down

Previously, I wrote about using coroutines in RethinkDB. Coroutines are a nice alternative to callbacks because they are easier to program in, and they are a nice alternative to threads because of their greater performance. But how fast are they?

Just using an off-the-shelf library like libcoroutine isn’t as fast as you might think. The graph below shows the huge performance degradation of a naive implementation of coroutines (the short red bar) compared to the old callback-based code (the blue bar on the left). But with the right set of …

Multi Slicing
+0 Vote Up -2Vote Down

The basic data structure that powers databases is called a B-tree. This is where you actually store the user’s data. B-trees are great because you can put huge amounts of data in them and access remains fast. In fact, the naive strategy of putting a whole data set into one B-Tree doesn’t break down because of access time. It does, however, break down when you try to support a multiaccess paradigm.

Six years ago, multiaccess was nice. Now that processors have multiple cores, it’s crucial. Four cores fighting over one B-tree means a lot of wasted processor time. In a multiaccess scheme, different cores can concurrently access data. This gets tricky. You can go …
