Fault Tolerant Grid Migration Using Network Storage
We will present a protocol of fault tolerant grid migration system using network storage. Our proposed grid migration system has capability to recover from fault in autonomic manner. We also implemented a grid migration system using Globus Toolkit4 and the network storage. Performance evaluation will be reported to show effectiveness of the fault recovery.
متن کاملReparallelization and migration of OpenMP applications in grid environments
Grid computing opens up a new computing infrastructure and users gain access to a vast landscape of computing resources that are spread over the world and that are instantly accessible through the Internet. In the future, computational Grids are expected to deliver high-end computing power at the user’s finger tips. Today, typical users of a computational Grid only exploit a single cluster and ...
متن کاملG-javampi: a Grid Middleware for Transparent Mpi Task Migration∗
Resources in a grid are dynamic, heterogeneous, and widely distributed. End users need a simple and efficient way to aggregate and utilize these diverse resources. We introduce a grid middleware called G-JavaMPI, which combines a high-level message passing interface with the Java language to support portable messaging-passing programming in a grid. Different from traditional MPI implementations...
متن کاملIdentifying Job Migration Characteristics in Decentralized Grid Scheduling Scenarios
This paper explores the characteristics of job migration between different parallel compute sites in a decentralized Grid scenario sharing a central job pool. Independent users are assumed to submit their jobs to their local site MPP installation, which in turn is allowed to decline the local execution of jobs by offering them to a central job pool. The simulation results are obtained using rea...
متن کاملScheduling in Heterogeneous Grid Environments: The Effects of Data Migration
Computational grids have the potential for solving large-scale scientific problems using heterogeneous and geographically distributed resources. However, a number of major technical hurdles must be overcome before this goal can be fully realized. One problem critical to the effective utilization of computational grids is efficient job scheduling. Our prior work addressed this challenge by defin...
