lockless
Lacking any bolt
Lockless describes something without a lock—a door, a box, a gate that anyone can open.
In computing, lockless refers to algorithms or data structures designed to operate without mutual exclusion locks, allowing multiple threads to access shared resources simultaneously: lockless queues, lockless programming.
The technical sense emphasizes speed and avoiding bottlenecks in concurrent systems.
