Grid Application Performance Prediction: a Case Study in BROADEN
نویسنده
چکیده
The BROADEN (Business Resource Optimisation for Aftermarket and Design on Engineering Networks) project aims to build a Rolls-Royce Grid as a proving ground for utilising Grid services technology. One of the central applications in this project is XTO ((eXtract Track Order) which is used to facilitate distributed diagnostics support for aircraft engines. One of the key elements in BROADEN is the ability to predict XTO applications run-time. In this paper a SNAP-base (Service Negotiation Acquisition Protocol) resource broker is extended to include a QoS (Quality of Service) Manager which utilises a run-time historical database that allows for such prediction to take place. The performance results presented in terms of predicted run-time that the use of this manager can provide show the potential of this approach on a Grid test-bed.

متن کاملBuilding Online Performance Models of Grid Middleware with Fine-Grained Load-Balancing: A Globus Toolkit Case Study
As Grid computing increasingly enters the commercial domain, performance and Quality of Service (QoS) issues are becoming a major concern. To guarantee that QoS requirements are continuously satisfied, the Grid middleware must be capable of predicting the application performance on the fly when deciding how to distribute the workload among the available resources. One way to achieve this is by ...
متن کاملAnt colony algorithm as a high-performance method in resource estimation using LVA field; A case study: Choghart Iron ore deposit
Kriging is an advanced geostatistical procedure that generates an estimated surface or 3D model from a scattered set of points. This method can be used for estimating resources using a grid of sampled boreholes. However, conventional ordinary kriging (OK) is unable to take locally varying anisotropy (LVA) into account. A numerical approach has been presented that generates an LVA field by calcu...
