We consider the following balls-into-bins process with n bins andmballs: Each ball is equipped with a mutually independent exponential clock of rate 1. Whenever a ball’s clock rings, the ball samples a random bin and moves there if the number of balls in the sampled bin is smaller than in its current bin. This simple process models a typical load balancing problem where users (balls) seek a selfish...
In this paper we consider a wide class of discrete diffusion load balancing algorithms. The problem is defined as follows. We are given an interconnection network and a number of load items, which are arbitrarily distributed among the nodes of the network. The goal is to redistribute the load in iterative discrete steps such that at the end each node has (almost) the same number of items. In diffusion...
Renaming is a task in distributed computing where n processes are assigned new names from a name space of size m. The problem is called tight if m = n, and loose if m > n. In recent years renaming came to the fore again and new algorithms were developed. For tight renaming in asynchronous shared memory systems, Alistarh et al. describe a construction based on the AKSnetwork that assigns all names...
We study threshold-based load balancing protocols for weighted tasks. We are given an arbitrary graph G with n nodes (resources, bins) and m > n tasks (balls). Initially the tasks are distributed arbitrarily over the n nodes. The resources have a threshold and we are interested in the balancing time, i.e., the time it takes until the load of all resources is below the threshold. We distinguish...
Cloud computing has a major impact on today's IT strategies. Outsourcing applications from IT departments to the cloud relieves users from building big infrastructures as well as from building the corresponding expertise, and allows them to focus on their main competences and businesses. One of the main hurdles of cloud computing is that not only the application, but also the data has to be moved...
In this paper we consider load balancing in a static and discrete setting where a fixed number of indivisible tasks have to be allocated to processors. We assume uniform tasks but the processors may have different speeds. The load of a processor is the number of tasks assigned to it divided by its speed. We consider diffusion load balancing which works in rounds. In every round the processors are...
Balls-into-bins games for uniform bins are widely used to model randomized load balancing strategies. Recently, balls-into-bins games have been analysed under the assumption that the selection probabilities for bins are not uniformly distributed. These new models are motivated by properties of many peer-to-peer (P2P) networks, which are not able to perfectly balance the load over the bins. While previous...
