Description: Grid technologies have progressed towards a service-oriented paradigm that enables a new way
of service provisioning based on utility computing models, which are capable of supporting diverse
computing services. It facilitates scientific applications to take advantage of computing resources
distributed world wide to enhance the capability and performance. Many scientific applications in areas
such as bioinformatics and astronomy require workflow processing in which tasks are executed based on
their control or data dependencies. Scheduling such interdependent tasks on utility Grid environments need
to consider users’ QoS requirements. In this paper, we present a genetic algorithm approach to address
scheduling optimization problems in workflow applications, based on two QoS constraints, deadline and
budget.

Description: While the required reliability of the sensing
process can be expressed in terms of rarely enough overlooking the PU, we assume that the proper QoS for the SU is given by maintaining — with a given confidence level — a minimum
bandwidth availability for the SU in spite of PU dynamics. In this paper we present an overview of approaches which might be used
to achieve these objectives. In addition we point out, that both the sensing process and the secondary link maintenance (necessary to keep the required bandwidth in spite of e configuration due to detected PUs) require a significant spectrum overhead. We identify and elaborate a fundamental tradeoff in using these
overheads in either sensing or link maintenance, and present examples of its optimization. Platform: |
