WebAccelerating pointer chasing in 3D-stacked memory: Challenges, mechanisms, evaluation Abstract: Pointer chasing is a fundamental operation, used by many important data-intensive applications (e.g., databases, key-value stores, graph processing workloads) to traverse linked data structures. WebMar 8, 2024 · This is in contrast to chaining, which involves pointer chasing through a linked list. The hash table is a simple array of KeyValue items: struct KeyValue {uint32_t key; uint32_t value;}; The table uses power-of-two sizes instead of prime numbers because pow2/ AND masking is a fast single instruction and the modulo operator is much slower. This ...
