In this paper, we use a wildcard mask to implement the load balance method directly on switches or routers and add a user prediction mechanism to dynamically change the range of the wildcard mask, in this way, the load balance mechanism can be applied conforming to real service situations. In our experiment, we tested the accuracies of flow prediction with different prediction algorithms and compared...
Due to the demand for the mass distributed computing and efficient data transmission, grid systems start to integrate with P2P technology to support high-performance distributed computing. However, the workload on P2P grid computing systems could be highly variable and its unstable behavior could intensely affect the system performance. In general, the high variability of the workload leads to wrong...
In this paper we proposal a new scheduling system based on multi-clusters environments. The work we present is Adaptive Job Allocation Strategy (AJAS) in which the scheduler dispatches jobs that with self-scheduling scheme into appropriate resources across multi-clusters. The strategy focuses on how to increase resource utility, jobs via self-scheduling and dispatching jobs to nodes with similar performance...
In data grid, co-allocation architecture can be used to enable parallel transferring of data file from multiple replicas which stored in the different grid sites. Some schemes base on co-allocation model were proposed and used to exploit the different transfer rates among various client-server network links and to adapt dynamic rate fluctuations by dividing data into fragment. These schemes showed...
In data grid, co-allocation architecture was developed to enable parallel transferring of files from multiple replicas stored in the different servers. Several dynamic file transfer strategies based on co-allocation model have been proposed and used to exploit the different transfer rates among various client-server links and to address dynamic rate fluctuations by dividing files into multiple blocks...
In data grids, co-allocation architectures were developed to enable parallel downloads of datasets from selected replica servers. As Internet is usually the underlying network of a grid, network bandwidth plays as the key factor affecting file transfers between clients and servers. In this paradigm, there are still some challenges which need to be solved, such as to reduce differences in finish times...
Large-scale shared-memory multiprocessor systems are the current trend in high-performance multiprocessor systems, which are often divided into many nodes. These nodes contain a small number of processors connected by an internal bus. In this kind of system, load imbalance often occurs and can degrade the performance. This paper presents a cost-effective load balancing algorithm, which performs load...
