Network Bandwidth-aware job scheduling with dynamic information model for Grid resource brokers

Abstract

A resource broker with a user-friendly interface for job submission developed on a platform constructed using the Globus toolkit is proposed. The broker employs a domain-based network information model and dynamic version to measure network statuses, and also monitors and collects resource statuses and networkrelated information as the basis of its brokerage. A network bandwidth-aware job scheduling algorithm for brokering suitable Grid resources to communicationintensive jobs based on improving and preserving the advantages of our previously developed network information model is also proposed. Using timely information, the resource broker effectively matches Grid resources and user requests, thus improving job execution efficiency.

The scheduler for the grid­system based on the parameters monitoring of the computer components

“…The authors of [5] have presented the scheduling algorithm that accounts for the task input data allocation in the distributed system. In [6] the approach that considers the network and resource status dynamics in task scheduling has been proposed. The authors of [7] present task scheduling with accounting for the network channel capacity for intensive data exchange applications.…”

Resource Management in a Distributed Computer System with Allowance for the Level of Trust to Computational Components

“…Since distributed systems are frequently used as data stores, resource management mechanisms based on this approach are increasingly used. In [17][18][19][20][21], algorithms based on this approach are presented. Different economic models are developed for resource management in distributed systems.…”
