A Generalized Simultaneous Access Dictionary Machine
April 1991 (vol. 2 no. 2)
pp. 149-159

A simultaneous access design of a dictionary machine which supports insert, delete, andsearch operations is presented. The design is able to handle p accesses simultaneouslyand allows redundant accesses to occur. In the design, processors performing insert ordelete operations are free to perform other tasks after submitting their accesses to thedesign; processors that perform search operations get their response in O(log N) time.Compared to all sequential access designs of a dictionary which require O(p) time toprocess p accesses, the presented design provides much higher throughput; specifically,O(p/log p) times better. It also provides a fast mechanism to avoid the sequential accessbottleneck in any large multiprocessor system.
