Broker-Mediated Cloud-Aggregation Mechanism Using Markovian Queues for Scheduling Bag-of-Tasks (BoT) Applications

Ganesh Neelakanta Iyer and Bharadwaj Veeravalli


20.1 Introduction

Many data-intensive applications from several fields, including data mining [1] and computational biology [2], have been modeled as Bag-of-Tasks (BoT) applications. BoT applications are parallel applications whose tasks are independent of each other [3], [4]. In other words, a BoT application is an application that executes in terms of tasks [5]. Examples include simulation of a large number of independent trials or events ...
