Data Replication in Data Intensive Scientific Applications with Performance Guarantee
TL;DR: This paper designs a polynomial time centralized replication algorithm that reduces the total data file access delay by at least half of that reduced by the optimal replication solution, and designs a distributed caching algorithm, which can be easily adopted in a distributed environment such as Data Grids.

A Bee Colony based optimization approach for simultaneous job scheduling and data replication in grid environments
TL;DR: This paper presents a novel Bee Colony based optimization algorithm, named Job Data Scheduling using Bee Colony (JDS-BC), which consists of two collaborating mechanisms to efficiently schedule jobs onto computational nodes and replicate datafiles on storage nodes in a system so that the two independent, and in many cases conflicting, objectives are concurrently minimized.

Fat-trees: universal networks for hardware-efficient supercomputing
TL;DR: In this article, the authors presented a new class of universal routing networks, called fat-trees, which might be used to interconnect the processors of a general-purpose parallel supercomputer, and proved that a fat-tree of a given size is nearly the best routing network of that size.
