A green power management scheme is proposed to determine how many physical machines should be run or turned off based on the gross occupied resource weight ratio of the virtual machine cluster. The gross occupied resource weight ratio is defined as the ratio of the sum of resource weights of all virtual machines over the sum of available resource weights of all running physical machines. When the...
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...
With the rapid proliferation of hardware devices, cluster computing has encountered the problem of heterogeneous resources. We have constructed a multi-cluster system that works with and without storage devices, and evaluated the system performance. We dispatch jobs with the strategy we propose to make the best use of system resources. In this paper we introduce this new scheduling system based on...
Grid computing is increasingly used by organizations to achieve high performance computing and heterogeneous resources sharing. These grids may span several domain administrations via Internet. As a result of this, it may be difficult to monitor, control and manage those machines and resources. This paper aims at providing a multi-platform grid monitoring service which can monitor resources such as...
Increases in mobile device processing power, storage capacity, and connectivity in recent years have led to a rapid rise in mobile device use. But mobile users face challenges in making connections with other users in order to share resources. To address this issue, we propose an architecture that uses peer-to-peer protocol to establish a resource sharing platform for mobile devices, combined with...
Parallel loop scheduling on grid environments is a challenging problem, especially for loops with irregular workload distribution. In the past, this problem of load imbalance resulting from irregular workload was not explicitly addressed. This paper proposes a new approach to schedule loop iterations with irregular workload on grid environments. Based on knowledge-based estimation of workload, the...
In this paper, we construct four DRBL-based diskless Linux PC clusters and install Globus Toolkit and Condor scheduler on the master node of each cluster. All diskless clusters can be merged into a powerful computing environment. To utilize the computing power, we propose a jobs allocation strategy for application execution. We use HPL to conduct some performance evaluations and analyze those data...
We integrate the technologies of high availability and load balancing clusters that combine features of both of these cluster types, increasing both the availability and scalability of services and resources. This type of cluster setup is commonly used for Web-based VOD servers.
A cluster is a collection of independent and cheap machines, used together as a supercomputer to provide a solution. In this paper, a PC cluster consisting of one master node and nine disk-less slave nodes (10 processors), is proposed and built for parallel rendering purposes. The system architecture and benchmark performances of this cluster are also presented. Internet computing and grid technologies...
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...
