This paper discusses how locality between objects a ects the performance, and proposes a software architecture for enhancing locality while keeping load-balance reasonable at the minimum sacri ce of runtime overhead. Objects are created locally by default and long-lived objects are selectively migrated during garbage collection. By enhancing locality, message passings are likely to be local and...

Vertical handover is essential to ensure service continuity in a heterogeneous network. Multi-criteria decision is proposed to reduce handover rate and optimizing usage of network resource compared to the conventional handover decision, which used single criteria. The algorithm is evaluated by assessing the performance in terms of number of handoff, load balance index, and network blocking prob...

Load Balancing (LB) has been an increasingly important issue for handling computational intensive task in a grid system. By developing strategies that can schedule such tasks to resources in a way that balance out the load, the total processing time will be reduced with improved resource utilization. In this paper, an Enhanced Genetic Algorithm (EGA) is proposed for achieving task scheduling wi...

In Hypertable ranges of table data are stored and accessed on different nodes and allows for flexible management of the underlying hardware. Overall performance is sensitive to the balance of range load across the cluster. The project developers aim to create a simple interface to allow researchers to design experimental load balancing strategies that incorporate machine learning and optimizati...

In this paper, we study about diffusion load balancing algorithms with their implementation. Our analysis is based on different topologies in simulated environment. The purpose of load balancing algorithm is to distribute the excess load of processor to lightly loaded processor. The objective of this analysis is to find out best stable network amongst chain, 2D and 3D Mesh networks in this diff...

In this paper, we present a parallel simulated annealing (SA) on distributed computing resources. The parallel SA include two types of cooperation mechanism: inner group and inter group cooperations. In the inner group cooperation, SA processes start from the same initial point, however, move to different direction. That is, two concepts: concentration and diversity are included. On the other h...

We report on the improvements that can be achieved by applying machine learning techniques, in particular reinforcement learning, for the dynamic load balancing of parallel applications. The applications being considered here are coarse grain data intensive applications. Such applications put high pressure on the interconnect of the hardware. Synchronisation and load balancing in complex, heter...

The load distribution in a grid may vary leading to the bottlenecks and overloaded sites. We describe a hierarchical dynamic load balancing protocol for Grids. The Grid consists of clusters and each cluster is represented by a coordinator. Each coordinator first attempts to balance the load in its cluster and if this fails, communicates with the other coordinators to perform transfer or recepti...

In this paper, we present that a tree machine can be embedded into incomplete hypercube with expansion 1, load 1, dilation 2 and congestion 2. This result is better than the expansion (2+2)/(2+2-2) in [14]. Then we consider how to embed a large tree machine into a hypercube for considering load-balance. We have shown that a tree machine TMh (h1) can be embedded into a hypercube Hh+1 with dilat...

OBJECTIVE Angiotensin receptor blockers (ARBs) produce a lower sodium (Na) balance, and the natriuretic effect is enhanced under Na deprivation, despite falls in blood pressure (BP) and glomerular filtration rate (GFR). METHODS The effect of additional hydrochlorothiazide (HCTZ; 12.5 mg/day) to ARB treatment (valsartan; 80 mg/day) on glomerulotubular Na balance was evaluated in 23 patients wi...
