Abstract. Knowing the performance of an application in a Grid environment is an important issue in application development and for scheduling decisions. In this paper we describe t...
This paper examines the issue of dynamically scheduling applications on a wide-area network computing system. We construct a simulation model for wide-area task allocation problem...
Grid users may experience inconsistent performance due to specific characteristics of grids, such as fluctuating workloads, high failure rates, and high resource heterogeneity. Alt...
In this paper we study a fault tolerant model for Grid environments based on the task replication concept. The basic idea is to produce and submit to the Grid multiple replicas of ...
With the advent of Grid computing, more and more highend computational resources become available for use to a scientist. While this opens up new avenues for scientific research,...
