to a single server. However, in-memory server pools host an extremely large number of items, and granting a lease per item requires fine-grained leasing that is not supported in prior datacenter lease managers. This paper presents Centrifuge, a datacenter lease manager that solves this problem

sell many assets simultaneously. Often these assets, like U.S. treasury bills, are interchangeable. However, sometimes the assets and the bids for them are distinct. This happens frequently, as in the U.S. Department of the Interior's simultaneous sales of off-shore oil leases, in some private

Today’s Internet Service Providers (ISPs) serve two roles: managing their network infrastructure and providing (arguably limited) services to end users. We argue that coupling these roles impedes the deployment of new protocols and architectures, and that the future Internet should support two

and the details of managing a specific resource or service. It offers an extensible interface for custom resource management policies and new resource types. We show how Shirako enables applications to lease groups of resources across multiple autonomous sites, adapt to the dynamics of resource competition

users request resource leases, where leases can request either as-soon-as-possible (“best-effort”) or reservation start times. We present the design of a lease management architecture, Haizea, that implements leases as virtual machines (VMs), leveraging their ability to suspend, migrate, and resume

Abstract: The popularity of developing sportfish leases is increasing rapidly in the South, much as development of hunting leases has done over the past three decades. This trend is occurring because an increasing number of: (1) landowners realize that their ponds and reservoirs are valuable

This paper develops a dynamic model of firm financing based on the need to collateralize promises to pay with tangible assets, leading to a unified theory of optimal investment, capital structure, leasing, and risk management. Tangible assets required for production restrict leverage. Leasing

Genetic Algorithms apply the concepts of evolution to the solving of mathematical problems. This idea was first exploited by J.Holland in 1975 and has been applied to areas such as engineering, computing, biology and music. This paper will outline the basics of the genetic algorithm, and will apply the genetic algorithm approach to the problem of asset allocation, firstly using the traditional mean variance approach and secondly using a direct utility maximisation method for a step utility hction. We will compare the performance of genetic algorithms with an alternative method of opthisation, Newton's method.

We present opportunistic renewal, a lease management protocol designed to keep distributed le systems or dis-tributed shared memories consistent in the presence of a network partition or other computer failures. Our treatment includes an analytical model of the protocol that compares performance
