Coupling multiple nodes for high performance transaction processing has become increasingly attractive for reasons of capacity, availability and cost. The shared disks (SD) cluster couples computing nodes via a highspeed network and share a common database at the disk level. This paper proposes a transaction routing algorithm that exploits access affinities of transactions to rationalize worklo...

Distributed systems are characterized by resource multiplicity and system transparency. A variety of widely differing techniques and methodologies for scheduling processes of a distributed system have been proposed. These techniques are broadly classified into three types: task allocation approach, load balancing, load sharing. The main goal of load balancing is to equalize the workload among t...

Symmetric mathematical programming is used to analyze the optimality of balancing workloads t~ maximize the expected production in a single-serve~closed queuing network model of a flexible manufacturing system (FMS). In particular, using generalized concavity we prove that, even though the production function is not concave, balancing workloads maximizes the expected production in certain types...

Based on cluster, a dynamic parallel mode–the MSGD(MasterSlave-Gleaner-Dynamic) mode is presented in this paper. Combining the load balancing with the MSG (Master-Slave-Gleane) mode, this mode brings in a load balancing strategy–task pool, which can coordinate the workload of each node effectively. A volume rendering algorithm called Splatting is used to test the performance of this mode on IBM...

In this paper, we present a multithreaded approach for the automatic load balancing of adaptive nite element (FE) meshes. The platform of our choice is the EARTH multithreaded system which ooers suucient capabilities to tackle this problem. We implement the adaption phase of FE applications on triangular meshes, and exploit the EARTH token mechanism to automatically balance the resulting irregu...

Cloud computing emerges as an alternative to promote quality of service for data-driven applications. Database Management Systems must be available to support the deployment of cloud applications resorting to databases. Many solutions use database replication as a strategy to increase availability and decentralize the workload of database transactions between replicas. By the distribution of da...

We consider the Airspace Sectorization Problem (ASP) in which airspace has to be partitioned into a given number of sectors, each of which being assigned to a team of air traffic controllers. The objective is to minimize the coordination workload between adjacent sectors while balancing the total workload of controllers. Many specific constraints, including both geometrical and aircraft related...

INTRODUCTION Hospitals pursue different goals at the same time: excellent service to their patients, good quality care, operational excellence, retaining employees. This requires a good balance between patient needs and nursing staff. One way to ensure a proper fit between patient needs and nursing staff is to work with a workload management method. In our view, a nursing workload management me...

In computer graphics, ray tracing is a popular technique for rendering images with computers. In this project we implemented a serial version of ray tracing in C, and three parallelized versions in CUDA. We conducted experiments to demonstrate speedup with CUDA, as well as the importance of balancing workload among threads.

The wireless sensor network (WSN) can be applied for many application such as industrial, military application etc., The WSN can be used for sensor nodes to collect the data at the regular intervals. In this paper, we examine the load balancing in clustering method and dual data uploading in wireless sensor networks. To avoid the overloading of any single resource and to optimize the use of max...
