This paper presents the results of a load balancing study carried out on the distributed operating system Amoeba. The study is intended to investigate the e ectiveness of di erent load balancing methodologies on a workstation-based system, specifying job initiation vs. process migration. The results indicate that both methods can improve system performance, such as response time. The results al...

This paper is a survey of existing policies and mechanisms for load sharing in loosely-coupled distributed computing systems, where user machines are personal workstations interconnected by a local area network. We are interested only in centralized operating systems providing mechanisms for remote process communication, thus we do not study distributed operating systems in which load balancing...

Cloud computing offers a cost-effective and elastic computing paradigm that facilitates large scale data storage and analytics. By deploying virtualization technologies in the datacenter, cloud enables efficient resource management and isolation for various big data applications. Since the hotspots (i.e., overloaded machines) can degrade the performance of these applications, virtual machine mi...

It is significant to apply load-balancing strategy to improve the performance and reliability of resource in data centers. One of the challenging scheduling problems in Cloud data centers is to take the allocation and migration of reconfigurable virtual machines (VMs) as well as the integrated features of hosting physical machines (PMs) into consideration. In the reservation model, the workload...

The growing popularity of cloud computing as a platform for deploying internet scale applications has seen a large number of web applications being deployed in the cloud. These applications (or tenants) are typically characterized by small data footprints, different schemas, and variable load patterns. Scalable multitenant database management systems (DBMS) running on a cluster of commodity ser...

This paper presents a new dynamic load-balancing algorithm for hypercube multicomputers with faulty nodes. The emphasis in our method is on obtaining global load information and performing task migration using ``short paths'' in a synchronous manner so that a minimal amount of communication overhead is required. To accomplish this, we present an algorithm for constructing a new logical topology...

For the purpose of load balancing, migration of VM instances or processes in cloud environment is quite useful. However, the live migration of VM is insecure. There is necessity of incorporating encryption and authentication mechanisms during migration process. An attempt is made to secure live migration of virtual machine and running processes from one machine to another. In this system, the v...

Overview We present • a problem setting for dynamic load balancing on the Internet as Grid, • an adaptive method according to initial load: the optimal flow is directly obtained, the conditions of migration for the bottleneck edges are relaxed by bypasses, • simulation results show the number of rounds of the migration is decreased by adaptive bypasses on a cactus.

Is process migration useful for load balancing? We present experimental results indicating that the answer to this question depends largely on the characteristics of the applied workload. Experiments with our Shiva system, which supports remote execution and process migration, show that only those CPU-bound workloads which were generated using an unrealistic exponential distribution for executi...

In this paper, we describe a single system image (SSI) architecture for distributed systems. The SSI architecture is constructed through three components: single process space (SPS), process migration, and dynamic load balancing. These components attempt to share all available resources in the cluster among all executing processes, so that the distributed system operates like a single node with...
