The HP AutoRAID hierarchical storage system

by John Wilkes, Richard Golding, Carl Staelin, Tim Sullivan - ACM Transactions on Computer Systems , 1995
"... Configuring redundant disk arrays is a black art. To configure an array properly, a system administrator must understand the details of both the array and the workload it will support. Incorrect understanding of either, or changes in the workload over time, can lead to poor performance. We present a ..."

a solution to this problem: a two-level storage hierarchy implemented inside a single diskarray controller. In the upper level of this hierarchy, two copies of active data are stored to provide full redundancy and excellent performance. In the lower level, RAID 5 parity protection is used to provide

SMARTS: Accelerating Microarchitecture Simulation via Rigorous Statistical Sampling

by Roland E. Wunderlich, Thomas F. Wenisch, Babak Falsafi, James C. Hoe - in Proceedings of the 30th annual international symposium on Computer architecture , 2003
"... Current software-based microarchitecture simulators are many orders of magnitude slower than the hardware they simulate. Hence, most microarchitecture design studies draw their conclusions from drastically truncated benchmark simulations that are often inaccurate and misleading. This paper presents ..."

Building Diverse Computer Systems

by Stephanie Forrest, Anil Somayaji , David H. Ackley
"... Diversity is an important source of robustness in biological systems. Computers, by contrast, are notable for their lack of diversity. Although homogeneous systems have many advantages, the beneficial effects of diversity in computing systems have been overlooked, specifically in the area of compute ..."

of computer security. Several methods of achieving software diversity are discussed based on randomizations that respect the specified behavior of the program. Such randomization could potentially increase the robustness of software systems with minimal impact on convenience, usability, and efficiency

Encapsulation and Inheritance in Object-Oriented Programming Languages

by Alan Snyder , 1986
"... Object-oriented programming is a practical and useful programming methodology that encourages modular design and software reuse. Most object-oriented programming languages supportdata Abstraction by preventing an object from being manipulated except via its defined external operations. In most lang ..."

inheritance and encapsulation and develops requirements for full support of encapsulation with inheritance. Introduction. Object-oriented programming is a practical and useful programming methodology that encourages modular design and software reuse. One of its prime features is support for data Abstraction

BCube: A High Performance, Server-centric Network Architecture for Modular Data Centers

by Chuanxiong Guo, Guohan Lu, Dan Li, Haitao Wu, Xuan Zhang, Yunfeng Shi, Chen Tian, Yongguang Zhang, Songwu Lu - In SIGCOMM , 2009
"... This paper presents BCube, a new network architecture specifically designed for shipping-container based, modular data centers. At the core of the BCube architecture is its server-centric network structure, where servers with multiple network ports connect to multiple layers of COTS (commodity off-t ..."

show that BCube can be seamlessly integrated with the TCP/IP protocol stack and BCube packet forwarding can be efficiently implemented in both hardware and software. Experiments in our testbed demonstrate that BCube is fault tolerant and load balancing and it significantly accelerates representative

Singularity: rethinking the software stack

by Galen C. Hunt, James R. Larus - SIGOPS Oper. Syst. Rev
"... Every operating system embodies a collection of design decisions. Many of the decisions behind WRGD\¶V PRVW SRSXODU RSHUDWLQJ systems have remained unchanged, even as hardware and software have evolved. Operating systems form the foundation of almost every software stack, so inadequacies in prese ..."

The M5 simulator: Modeling networked systems

by Nathan L. Binkert, Ronald G. Dreslinski, Lisa R. Hsu, Kevin T. Lim, Ali G. Saidi, Steven K. Reinhardt - IEEE Micro , 2006
"... TCP/IP networking is an increasingly important aspect of computer systems, but a lack of simulation tools limits architects ’ ability to explore new designs for network I/O. We have developed the M5 simulator specif-ically to enable research in this area. In addition to typical architecture simulato ..."
Abstract - Cited by 249 (22 self) - Add to MetaCart
simulator attributes, M5 provides features necessary for simulating networked hosts, including full-system capability, a detailed I/O subsys-tem, and the ability to simulate multiple networked systems deterministically. Our experience in simulating network workloads revealed some unexpected interactions

Model-driven Development of Complex Software: A Research Roadmap

by Robert France, Bernhard Rumpe - 29th Int. Conf. on Software Engineering , 2007
"... The term Model-Driven Engineering (MDE) is typically used to describe software development approaches in which abstract models of software systems are created and system-atically transformed to concrete implementations. In this paper we give an overview of current research in MDE and discuss some of ..."

of the major challenges that must be tackled in order to realize the MDE vision of software development. We argue that full realizations of the MDE vision may not be possible in the near to medium-term primarily because of the wicked problems involved. On the other hand, at-tempting to realize the vision

GOLD: A Parallel Real-Time Stereo Vision System for Generic Obstacle and Lane Detection
