With the rapid advances in communication and networking, especially in Grid technique, an increasing number of applications will involve computing systems. This article focus that how to schedule system resources in reason and explore the dynamic scheduling method to the parallel tasks in the federation. According to task scheduling of content and objectives in the simulation grid, the HLA federate...
Predicting timing behavior is key to reliable real-time system design and verification, but becomes increasingly difficult for current multiprocessor systems on chip. The integration of formerly separate functionality into a single multicore system introduces new inter-core timing dependencies, resulting from the common use of the now shared resources. In order to conservatively bound the delay due...
Abstract-In this paper we focus on resource allocation for next generation wireless communication systems with aggregation of multiple Component Carriers (CCs), i.e., how to assign the CCs to each user, and how to multiplex multiple users in each CC. We first investigate two carrier load balancing methods for allocating the CCs to the users- Round Robin (RR) and Mobile Hashing (MH) balancing by means...
This paper addresses stochastic dynamic assignment of perishable goods in a scale-free network. We develop an agent-based simulation model in which the supplies and demands for a single perishable commodity are generated at each node (agent) in the network. We match supplies and demands with several pre-specified assignment rules and given various commodity decay durations. A utility is associated...
Complicated method and technology have been introduced into business workflow to solve their cooperation and load balancing. However, as combination of data management and flow management, scientific workflow's load balancing is less researched. So the phenomena of conflicting scheduling and load unbalance often occur. In this paper, we analyze functional framework and load consumption of scientific...
In hybrid heterogeneous and dynamically changing distributed grid environment, how to assign tasks to appropriate resources is one of the most challenging techniques. In this paper, we present a novel grid task assignment model and corresponding algorithm based on agents, small-world network model theory, and power-law. With the help of agents to assign tasks, the proposed model and algorithm can...
Web services over the Web had became more and more, and makes the requester to use tools to search for suitable Web services available throughout the globe. Web services QoS management frameworks had proposed such as QoS specification, Qos comprehensive quality, QoS monitoring of Web services and so on. In this paper, a model is investigated that not only based on QoS specification, Qos comprehensive...
Efficient mapping of logical processes to physical processes is one of key technologies to accelerate parallel performance simulation. Aiming at minimizing the communications between SMP nodes and between host physical processes, this paper presents a novel method named TPsmp-LP3M. It automatically extracts communication pattern of logical processes from trace and then generates a two-phase mapping...
A grid system connects a huge number of computers in the Internet. It integrates the distributed computational resources and data resources. A complex grid system needs to have a characteristic of self-managing. Autonomic computing aims to overcome the rapidly growing complexity of computing system management. It can be implemented to manage complex computing resources in grid systems. We present...
To cope with rapidly increasing Internet usage nowadays, providing Internet services using multiple servers has become a necessity. To ensure sufficient service quality and server utilization at the same time, effective methods are needed to spread load among servers properly. Existing load balancing methods often assume servers are homogeneous and consider only one type of resource, such as CPU....
This paper presents a comprehensive load balancing approach using priority based migration (PBM) mechanism for a trusted small scale distributed computing environment. A process migration server (PMS) that acts as a cluster management server reduces latency time in migrated process execution; leading to no starvation condition for any process thus achieving uniform distribution of load among all the...
As a consequence of Moore's law, the size of integrated circuits has grown extensively, resulting in simulation becoming the major bottleneck in the circuit design process. In this paper, we examine the performance of a parallel Verilog simulator on large, real designs. As previous work has made use of either relatively small benchmarks or synthetic circuits, the use of these circuits is far more...
Scheduling is an important issue in computational grid. In computational grid, computing resources are connected through networks. So, if we want to take advantage of computational grid, an efficient scheduling algorithm is necessary to assign jobs to the appropriate nodes. Our adaptive load sharing algorithms uses a timer to find a receiver/sender. If receiver does not find a sender it broadcasts...
We describe the various aspects involved in building FastTrans, a scalable, parallel microsimulator for transportation networks that can simulate and route tens of millions of vehicles on real-world road networks in a fraction of real time. Vehicular trips are generated using agent-based simulations that provide realistic, daily activity schedules for a synthetic population of millions of intelligent...
Telecommunication companies believe that the video-on-demand market will expand heavily in the near future. The service providers are interested in the deployment of video-on-demand (VoD) systems with large numbers of videos. As the number of videos and customers increases at a VoD system, two problems are faced. The first problem is the manual video allocation of multiple copies of videos to the...
With the development of internet technology, the entire amount of data on the internet has shown the explosive growth. Some researchers have paid their attention to find an effective way to store and manage these data. In this paper, we introduce a load rebalancing algorithm to solve the load balancing problem among all chunk servers(compute nodes) in the distributed file system; it also ensures that...

The testing results, compared with weighted round robin algorithm and weighted least connections...
Cloud data centers (CDCs) provide key infrastructure for cloud computing. Allocating computing resources is very important for the CDCs to function efficiently. Current allocation of resources in CDCs is mostly dedicated and static. However, workloads for cloud applications are highly variable which cause poor application performance, poor resource utilization or both. In this paper, adaptive dimensioning...
In peer-to-peer (P2P) systems, one important technique to improve the effectiveness of blind search is to proactively replicate file, which can lighten peers' load as well. But for autonomy and selfishness of peers in P2P systems, some peers are not willing to contribute their storage to save replications, which cannot be created successfully in this case. This paper presents a replication method...
Node clustering is an effective solution for achieving good performance and high reliability for peer-to-peer (P2P) systems. To improve the performance of a clustered P2P system, it is important to balance the service load among the clusters in the system. In this paper, we describe a diffusive load balancing scheme for clustered P2P systems, which dynamically adjusts the size of the clusters, by...
