Performance Analysis of Multiple Site Resource Provisioning: Effects of the Precision of Availability Information

Abstract

Emerging deadline-driven Grid applications require a number of computing resources to be available over a time frame, starting at a specific time in the future. To enable these applications, it is important to predict the resource availability and utilise this information during provisioning because it affects their performance. It is impractical to request the availability information upon the scheduling of every job due to communication overhead. However, existing work has not considered how the precision of availability information influences the provisioning. As a result, limitations exist in developing advanced resource provisioning and scheduling mechanisms. This work investigates how ..
