Sensitivity Analysis on Hardware Resources in SMT Processors

by Naveen Davanam, Ho Young Kim, Byeong Kil Lee, Eugene John
"... The microprocessor performance is increased by allowing multiple threads per clock cycle to issue instructions in simultaneous multithreading processors. Shared hardware resources are the key components of SMT processor performance. In SMT processors, impact to the performance will not be same among ..."

Exokernel: An Operating System Architecture for Application-Level Resource Management

by Dawson R. Engler, M. Frans Kaashoek, James O’toole , 1995
"... We describe an operating system architecture that securely multiplexes machine resources while permitting an unprecedented degree of application-specific customization of traditional operating system abstractions. By abstracting physical hardware resources, traditional operating systems have signifi ..."

Evolving Electronic Robot Controllers that Exploit Hardware Resources

by Adrian Thompson - In , 1995
"... . Artificial evolution can operate upon reconfigurable electronic circuits to produce efficient and powerful control systems for autonomous mobile robots. Evolving physical hardware instead of control systems simulated in software results in more than just a raw speed increase: it is possible to exp ..."

Focused crawling: a new approach to topic-specific Web resource discovery

by Soumen Chakrabarti, Martin van den Berg, Byron Dom , 1999
"... The rapid growth of the World-Wide Web poses unprecedented scaling challenges for general-purpose crawlers and search engines. In this paper we describe a new hypertext resource discovery system called a Focused Crawler. The goal of a focused crawler is to selectively seek out pages that are relevan ..."

that are likely to be most relevant for the crawl, and avoids irrelevant regions of the Web. This leads to significant savings in hardware and network resources, and helps keep the crawl more up-to-date. To achieve such goal-directed crawling, we designed two hypertext mining programs that guide our crawler: a

Hardware Resource Virtualization for Dynamically Partially Reconfigurable Systems

by Chun-hsian Huang, Student Member, Pao-ann Hsiung, Senior Member
"... Abstract—The dynamic partial reconfiguration technology enables an embedded system to adapt its hardware functionalities at run-time to changing environment conditions. However, reconfigurable hardware functions are still managed as conventional hardware devices, and the enhancement of system perfor ..."

Hardware resource allocation for hardware/software partitioning in the lycos system

by Jesper Grode, Peter V. Knudsen, Jan Madsen - In Proceedings of Design, Automation & Test in Europe (DATE , 1998
"... This paper presents a novel hardware resource alloca-tion technique for hardware/software partitioning. It al-locates hardware resources to the hardware data-path us-ing information such as data-dependencies between op-erations in the application, and profiling information. The algorithm is useful a ..."

Xen and the art of virtualization

by Paul Barham, Boris Dragovic, Keir Fraser, Steven Hand, Tim Harris, Alex Ho, Rolf Neugebauer, Ian Pratt, Andrew Warfield - IN SOSP , 2003
"... Numerous systems have been designed which use virtualization to subdivide the ample resources of a modern computer. Some require specialized hardware, or cannot support commodity operating systems. Some target 100 % binary compatibility at the expense of performance. Others sacrifice security or fun ..."

SPINS: Security Protocols for Sensor Networks

by Adrian Perrig, Robert Szewczyk, Victor Wen, David Culler, J. D. Tygar , 2001
"... As sensor networks edge closer towards wide-spread deployment, security issues become a central concern. So far, the main research focus has been on making sensor networks feasible and useful, and less emphasis was placed on security. We design a suite of security building blocks that are optimized ..."
