Distributed system may be considered as a collection of resources shared by different users. Distributed systems provide methods for sharing and aggregation of resources. Resources may be storage systems, computer machines, hardware devices and other specialized devices. Load balancing is a technique which can be used to improve the performance of distributed system by allowing load migration f...

This paper concentrates on load management methods for multiprocessor systems with distributed memory. Most of the programs running on these machines do not create new processes during runtime and there is usually no sharing of nodes between multiple users. This causes load movement by process migration to be indispensable. We implemented a testbed to nd out which load parameters are signiicant...

Atmospheric precipitation leads to the increase of moisture in subgrade. The and soil migration subgrade is a key scientific problem evaluating service performance resolving or preventing mud pumping. Using self-developed testing system as well numerical simulation model, detailed study dynamic hydraulic characteristics, water mechanism, fine pumping properties was conducted. results showed tha...

Task migration is an eeective strategy to achieve load balancing and high resource utilization in a meta-computing environment. In this paper, we argue that traditional task migration methods take into account only the computation, and neglect any necessary data migration. Accordingly, we introduce a new deenition of a task, propose a novel dynamic task migration scheme, and evaluate this schem...

Virtualization technology plays a great role in cloud computing. Virtualization supports creation and migration of virtual machines (VM) on physical hosts. Live migration provides the load balancing of virtual machine. One of the objectives of live migration is that it should have minimum migration time as well as downtime so that application running on VM will be suspended for negligible time....

Providing the ability to increase or decrease allocated resources on demand as the transactional load varies is essential for database management systems (DBMS) deployed on today’s computing platforms, such as the cloud. The need to maintain consistency of the database, at very large scales, while providing high performance and reliability makes elasticity particularly challenging. In this thes...

Bird migration requires high energy expenditure, and long-distance migrants accumulate fat for use as fuel during stopovers throughout their journey. Recent studies have shown that long-distance migratory birds, besides accumulating fat for use as fuel, also show adaptive phenotypic flexibility in several organs during migration. The migratory routes of many songbirds include stretches of sea a...

We developed a phase-field model to study the stress-driven grain boundary migration in elastically inhomogeneous polycrystalline materials with arbitrary elastic inhomogeneity and anisotropy. The dependence of elastic stiffness tensor on grain orientation is taken into account, and the elastic equilibrium equation is solved using the Fourier spectral iterative-perturbation method. We studied t...

Content Distribution Networks (CDNs) are highly advanced features for the Internet, and provide low latency, scalability, fault tolerance, and load balancing. One of the most important issues to realize these advantages of CDNs is to consider dynamic content allocation to deal with temporal load fluctuation. The dynamic content allocation provides mirroring of contents in order to distribute us...
