Recently, several hash table implementations have been proposed on GPUs. However, they have two pitfalls. Firstly, their synchronization approaches can only ensure the atomicity among individual operations.

A search algorithm that uses hashing consists of two parts. The first part is computing a hash function which transforms the search key into an array index. The ideal case is such that no two search keys hashes to the same array index. However, this is not always the case and is impossible to guarantee for unseen given data. Hence the second part of the algorithm is collision resolution. The …
