Efficient Execution of Tightly-Coupled Parallel Applications in Grid Computing Environments

Grid computing offers a model for solving large-scale scientific problems by uniting computational resources within multiple organizations to form a single cohesive resource for the duration of individual jobs. Such an infrastructure creates a pervasive and dependable pool of computing power that enables computational scientists to develop dramatically new classes of applications. Despite the appeal of Grid computing, developing applications that run efficiently in these environments often involves overcoming significant challenges. One challenge to deploying Grid applications across geographically distributed resources is overcoming the effects of latency between sites.
