An adaptive packed-memory array
2006
Proceedings of the twenty-fifth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems - PODS '06
Preserved Fulltext
Specifically, the cost to scan L consecutive elements is O(1 + L/B) memory transfers. This paper gives the first adaptive packed-memory array (APMA), which automatically adjusts to the input pattern. ...
The packed-memory array (PMA) is a data structure that maintains a dynamic set of N elements in sorted order in a Θ(N)-sized array. ...
ACKNOWLEDGMENTS We are grateful to Ziyang Duan for proposing an early uneven-rebalance strategy. We are grateful to Bradley Kuszmaul for suggesting that we focus on sequential inserts. ...

This enables the proposed filter module to access four packed pixels in a single 32-bit read operation and hence reduces memory access by a factor of four. ...

A number of compiler transformations have been developed to improve data reuse in cache and registers, thus reducing the total number of direct memory accesses in a program. ...
However, in an irregular or adaptive computation, the order of data access is not known until run time and that order may change dynamically. ...
