The unprecedented growth of available spatial data at geographically distributed locations coupled with the emergence of grid computing provides a strong motivation for designing a spatial grid which supports fast data retrieval and allows its users to transparently access data of any location from anywhere. This calls for efficient search and loadbalancing mechanisms. This paper focusses on dy...

Previous research efforts for building thread migration systems have concentrated on the development of frameworks dealing with a small local environment controlled by a single user. Computational Grids provide the opportunity to utilize a large-scale environment controlled over different organizational boundaries. Using this class of large-scale computational resources as part of a thread migr...

Process or object migration is a usefull technique for load balancing and dynamic reconnguration. This paper presents a new algorithm to preserve communication links in case of migration. The migration cost is higher than in existing algorithms but, in return, it leaves no residual dependencies and does not add any performance overhead over synchronous, asynchronous and stream-based communicati...

Prosthetic migration has been identified as a marker for future revision of cemented total hip reconstructions. This could be tested at a pre-clinical stage with dynamic loading experiments. The purpose of this study was to assess the effects of resting periods, which are a considerable part of the daily activity cycle, on the migration characteristics of femoral cemented stems. Ten polished Ex...

This paper looks at the design, implemntation and performance of RHODOS’ process migration facility which reflects RHODOS’ aspiration to support both load balancing and parallel execution on a distributed system. Following the presentation of the design issues, which reflect the requirements of both load balancing and parallel execution on a distributed system, research into an initial implemen...

Dispersal moves individuals from patches where their immediate ancestors were successful to sites where their genotypes are untested. As a result, dispersal generally reduces fitness, a phenomenon known as "migration load." The strength of migration load depends on the pattern of dispersal and can be dramatically lessened or reversed when individuals move preferentially toward patches conferrin...

DBMSs powering cloud application platforms must serve large numbers of applications with unpredictable load patterns while minimizing the operating cost leveraging the underlying pay-per-use infrastructure. We have designed ElasTraS, an Elastic TranSactional relational database for cloud platforms. ElasTraS is a confluence of two major design philosophies: traditional relational database system...

This paper presents a decentralized scheduling algorithm for dynamic load balancing in a self-organized desktop Grid environment. The proposed desktop Grid system allows volunteer nodes to join or leave freely at runtime, whereas user tasks can be launched at any node and make best use of computing resources by transparent process migration. To achieve rapid aggregation of runtime load informat...

Complex distributed object systems require dynamic migration algorithms thnt allocate and reallocate objects to respond to changes in the load or in the availabilip of the resources. I n this paper we present the Cooling and HotSpot migration algorithms that reallocate objects when the load on a processor is high or when the latency of a task is high. The algorithms have been iniplenietited as ...

In this paper a middleware architecture for distributed automotive systems that supports self-configuration by dynamic load balancing of tasks is presented. The inclusion of self-configurability is able to offer reliability within the multimedia network of the vehicle (Infotainment). Load balancing of tasks could be applied if an error occurred within the network. The error detection in the net...
