Continuing his series on concurrent programming, David Chisnall discusses how to remove the need for locking in some common cases, making use of lockless data structures.
When you start making a sequential system support concurrency, the easiest approach is to protect individual parts of it with locks. This design works, but it doesn’t always [...]
