In video-on-demand (VOD) systems, as the size of the buffer allocated to user requests increases, initial latency and memory requirements increase. Hence, the buffer size must be minimized. The existing static buffer allocation scheme, however, determines ...

The term virtualization leads to a wealth of definitions. A generic, rather popular scientific description is "In computing, virtualization is a broad term that refers to the abstraction of computer resources." IBM invented the virtualization technology ...

In this work, we develop an intelligent storage system framework for soft real-time applications. Modern software systems consist of a collection of layers and information exchange across the layers is performed via well-defined interfaces. Due to the ...

We discuss the rationale and design of a Generic Memory management Interface, for a family of scalable operating systems. It consists of a general interface for managing virtual memory, independently of the underlying hardware architecture (e.g. paged ...

Generative communication is the basis of a new distributed programming langauge that is intended for systems programming in distributed settings generally and on integrated network computers in particular. It differs from previous interprocess communication ...

VMware (www.vmware.com) is a virtual machine monitor for PCs. VMware provides isolated environments in which multiple x86 operating systems and applications can run concurrently on a standard PC. VMware has a lot of capabilities hidden under the covers, ...

Bigtable is a distributed storage system for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers. Many projects at Google store data in Bigtable, including web indexing, Google ...

The problem of rollback recovery in distributed shared virtual environments, in which the shared memory is implemented in software in a loosely coupled distributed multicomputer system, is examined. A user-transparent checkpointing recovery scheme and ...

Flash memory in various embedded systems such as the backing memory is frequently used in an active type of RFID reader. Because batteries are used in a shifting environment and shifting is seriously considered, embedded systems receive a lot of influence ...

Multi-attribute range queries on top of P2P networks have attracted much attention. Such research has direct application in grid resource monitoring and discovery. In existing research, the overheads (number of hops and number of messages required) of ...

Lately you may have begun hearing about High Performance NFS offerings and standards. But we all "know" NFS is not scalable. So what does High Performance NFS mean? FPGA implementation of parts of the file system? Really big caches? RDMA embedded in ...

A formalization of relationships between space-sharing, program behavior, and processor efficiency in computer systems is presented. Concepts of value and cost of space allocation per task are defined and then value and cost are combined to develop a ...

Interactive Poster Sessions serve as a valuable forum for presenting late-breaking research in computer-human interaction and receiving feedback from an interested body of viewers. The poster sessions held at this year's CHI '88 conference, May 15--19 ...

The material presented in this paper is part of the design plan of the core allocation portion of the ACSI-MATIC Programming System. Project ACSI-MATIC is concerned with the application of computer techniques to the activities of certain headquarters ...
