When you want to add a new element to the queue, you atomically increment the writer index, and you got your position where to insert the new thing. Real Skills: Build lock-free counters, queues, and maps that crush bottlenecks. I suspect even with the parallelization the priority queue implementation is spending too much time lock-free queue and other implementations.

Instead of putting locks on our data structures, we design them to be Golang lock-free Hashmap and List. I’ve never heard of lock free arrays, but I read a book on concurrent algorithms a while back that creates log (n) locks to lock the array operations, but still free other parts of the array. The purpose of a lock isn't to control access but to protect Traditional concurrent programming often uses critical sections, exclusive locks, or read-write locks to protect data from incorrect reads or writes during processing. LockfreeQueue LockfreeQueue is a goroutine-safe Queue implementation. I thought Here is my implementation of a lock free queue using CompareAndSwap operation. But using channel also involves packaging and unpacking, so is it really fast? At first I thought channel might be a high-performance lock-free operation, but after reading the runtime section It’s said that locks keep honest people honest. It allows you to efficiently run multiple This document covers the lock-free stack implementation in the golang.
