A Locality Preserving Cache-Oblivious Dynamic Dictionary
... Subseqently, Rahman, Cole, and Raman [35] presented and implemented a cache-oblivious dynamic dictionary based on exponential search trees [7, 8, 40] that supports insert and delete in O (logB N + log log N ) memory transfers and supports nger-type results. Their structure does not allow the scan o ...

The LevelArray: A Fast, Practical Long
... in the analysis, we will denote the n participants by p1 , p2 , . . . , pn , although the identifier i is unknown to process pi in the actual execution. Processes communicate through registers, on which they perform atomic read, write, test-and-set or compare-and-swap. Our algorithm only employs tes ...

RRB-Trees: Efficient Immutable Vectors - Infoscience
... In developing immutable hash maps for Clojure, lead developer Rich Hickey used Hash Array Mapped Tries (HAMT) [1] as the basis. HAMT’s use a 32-way branching structure to implement a mutable hash map. The immutable version, pioneered by Clojure, was created understanding that only the tree path need ...

SKIPLISTS
... Skip lists are a simple data structure that can be used in place of balanced trees for most applications. Skip lists algorithms are very easy to implement, extend and modify. Skip lists are about as fast as highly optimized balanced tree algorithms and are substantially faster than casually implemen ...
