RAM高效外部存储器排序

RAM-Efficient External Memory Sorting

Lars Arge, Mikkel Thorup

摘要:

近年来,大量的问题已经被认为是在外部存储器模型的计算,其中的复杂性措施是数据块的数量之间移动缓慢的外部存储器和快速的内部存储器(也称为I/O)。然而,在实践中,一旦获得I/O效率,内部存储器时间通常占总运行时间的主导地位。在本文中,我们研究的基本问题,同时是I/O高效和内存效率的RAM模型的计算算法。

英文摘要:

In recent years a large number of problems have been considered in external memory models of computation, where the complexity measure is the number of blocks of data that are moved between slow external memory and fast internal memory (also called I/Os). In practice, however, internal memory time often dominates the total running time once I/O-efficiency has been obtained. In this paper we study algorithms for fundamental problems that are simultaneously I/O-efficient and internal memory efficient in the RAM model of computation.
