Optimal File Allocation in a Multiple Computer System
A model is developed for allocating information files required in common by several computers. The model considers storage cost, transmission cost, file lengths, and request rates, as well as updating rates of files, the maximum allowable expected access times to files at each computer, and the storage capacity of each computer. The criterion of optimality is minimal overall operating costs (st...
متن کاملOptimal File Allocation in a Distributed Computer Network by Orthogonal Array Experiments
AbstreaThe problem of allocating files in a distributed network of interconnected computers, which was first addressed by Chu [l], is one of minimizing the overall operating cost while satisfying the finite computer storage capacity constraint and the bounds on the time to access the files. The overall operating oost consists of the cost of storing the files in the computers and the cost of tra...
متن کاملSIFA: A Scalable File System with Intelligent File Allocation
In this paper, we propose and evaluate a new NAS based system which is a consolidated file system in a network environment. The consolidated file system utilizes storage boxes cooperating as peers to provide all file system services, and presents itself to its NFS clients as a unified storage server. We have prototyped several key operations in this system. To provide more performance insights,...
متن کاملa benchmarking approach to optimal asset allocation for insurers and pension funds
uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...

We present a new Lagrangian-based iterative technique for rate{distortion optimization under multiple rate constraints. We show how for sets of \lin-ear" constraints this technique can be proven to be optimal up to a convex hull approximation. As an application we consider the problem of optimal buuer-constrained bit allocation. Our technique can be used to nd an excellent approximation to the ...
