Data Scheduling for Large Scale Distributed Applications
Mehmet Balman, Tevfik Kosar · 2007
Abstract: Current large scale distributed applications studied by large research communities result in new challenging problems in widely distributed environments. Especially, scientific experiments using geographically separated and heterogeneous resources necessitated transparently accessing distributed data and analyzing huge collection of information. We focus on data-intensive distributed computing and describe data scheduling approach to manage large scale scientific and commercial applications. We identify parameters affecting data transfer and also analyze different scenarios for possible use cases of data placement tasks to discover key attributes for performance optimization. We are planning to define crucial factors in data placement in widely distributed systems and develop a strategy to schedule data transfers according to characteristics of dynamically changing distributed environments. 1
