The Service Level Agreement (SLA) based grid superscheduling approach promotes coordinated resource sharing. Superscheduling is facilitated between administratively and topologically distributed grid sites by grid schedulers such as Resource brokers. In this work, we present a market-based SLA coordination mechanism. We based our SLA model on a well known contract net protocol. The key advantag...

The aim of this paper is to assess the most important area of long-term archivation using the multi-criteria analysis. This approach point out the section that should be put the most effort in during the design stage. The outline of the work covers basic prerequisites for the service level agreement conditions. Later on it continues with the service level agreement demands and uses the multi-cr...

Growth in the outsourcing of IT services has led many organizations to enter into negotiated contractual agreements with both internal and external service providers known as information technology service level agreements (IT SLAs). To further empirical research into IT SLAs, we present a methodological approach based on the theory of conceptual spaces that allows the content of these negotiat...

If a set of agents tries to reach an agreement, there will exist an Agreement Space that models the maximum valid space according to the individual constraints of each agent, regarding the terms of the agreement. Previous approaches to Agreement Spaces model them by means of a Counsellor Agent that will help to agents trying to obtain an agreement knowing all the possible terms in that agreemen...

Seminar Objectives To bring together researchers working in the field of intercultural communication pedagogy, particularly-but not exclusively-in higher education, so as to develop a dialogue around the following kinds of question:  What contribution can a discourse approach make to the learning/teaching of intercultural communication?  How far is intercultural communication necessarily inte...

Literature is rife with compelling ideas on simplifying storage management using service-level objectives (SLOs). However, very few of these ideas have actually been productized, despite the fact that many of the original ideas came from industry and were developed more than a decade ago. While many good research ideas do not become products, in this case, we believe that there are important re...

How adversely would your product be affected by the loss or gain of a data source? Can a data quality assessment help your product’s position in the negotiation? Through documenting a real-world case study, this presentation explores how one company’s internal Data Quality Scorecard system was used as leverage at the negotiation table. The paper examines how data quality can drive service-level...

Resource allocation for simulation applications in cloud simulation environment brings new challenges to infrastructure service providers. In order to meet the constraint of SLA and to allocate the available virtualized resources optimally, this paper first presents autonomic resource management architecture, and then proposes a resource allocation algorithm for infrastructure service providers...

Grid infrastructures are maturing to a point where they are attracting the interest of businesses in many application domains. While many large-scale on-line gaming platforms exist, they fail to take into consideration the potential business to business relationships when it comes to dynamic on-line game hosting. This work presents an initial implementation of the edutain@grid architecture to s...

A common workflow in science and engineering is to (i) setup and deploy large experiments with tasks comprising an application and multiple parameter values; (ii) generate intermediate results; (iii) analyze them; and (iv) reprioritize the tasks. These steps are repeated until the desired goal is achieved, which can be the evaluation/simulation of complex systems or model calibration. Due to ti...
