发明名称 Splash tables: an efficient hash scheme for processors
摘要 A computer implemented method, data processing system, and computer usable program code are provided for storing data items in a computer. A plurality of hash functions of data values in a data item are computed. A corresponding memory location is determined for one of the plurality of hash functions. The data item and a key portion and a payload portion of all data items are stored contiguously within the memory location. Also provided for are retrieving data items in a computer. A plurality of hash functions of data values in a probe key are computed. A corresponding memory location is determined for each of the plurality of hash functions. Data items in each memory location are examined to determine a match with the probe key. Responsive to a match, a payload of the matching stored data item is returned. All of the steps are performed free of conditional branch instructions.
