We present a new class of resizable sequential and concurrent hash map algorithms directed at both uni-processor and multicore machines. WebCuckoo Hashing is a technique for implementing a hash table. As opposed to most other hash tables, it achieves constant time worst-case complexity for lookups. Collisions are handled by evicting existing keys and moving them from one array to the other. This resembles the way a cuckoo chick pushes out an egg from the nest to make room for ...
