Lock free hash table
Witryna21 maj 2024 · A hash table is well suited for parallel computing because it can be accessed in a lock-free manner. The hash function can quickly find entries with a specific k-mer, which has advantages over sorting methods and can process deep sequencing data faster.

The basic idea of cuckoo hashing is to resolve collisions by using two or more hash functions instead of only one. In this implementation, we use two hash functions and two arrays (or tables).
