PVFS: A Parallel File System For Linux Clusters

by Philip H. Carns, Walter B. Ligon, III, Robert B. Ross, Rajeev Thakur - IN PROCEEDINGS OF THE 4TH ANNUAL LINUX SHOWCASE AND CONFERENCE , 2000
"... As Linux clusters have matured as platforms for low-cost, high-performance parallel computing, software packages to provide many key services have emerged, especially in areas such as message passing and networking. One area devoid of support, however, has been parallel file systems, which are criti ..."

Geography-informed Energy Conservation for Ad Hoc Routing

by Ya Xu, John Heidemann, Deborah Estrin - ACM MOBICOM , 2001
"... We introduce a geographical adaptive fidelity (GAF) algorithm that reduces energy consumption in ad hoc wireless networks. GAF conserves energy by identifying nodes that are equivalent from a routing perspective and then turning off unnecessary nodes, keeping a constant level of routing fidelity. GA ..."

studies of GAF show that it can consume 40% to 60% less energy than an unmodified ad hoc routing protocol. Moreover, simulations of GAF suggest that network lifetime increases proportionally to node density; in one example, a four-fold increase in node density leads to network lifetime increase for 3 to 6

Unmodified device driver reuse and improved system dependability via virtual machines

by Joshua Levasseur, Volkmar Uhlig, Jan Stoess, Stefan Götz - In Proceedings of the 6th Symposium on Operating Systems Design and Implementation , 2004
"... We propose a method to reuse unmodified device drivers and to improve system dependability using virtual machines. We run the unmodified device driver, with its original operating system, in a virtual machine. This approach enables extensive reuse of existing and unmodified drivers, independent of t ..."

technique requires minimal support infrastructure and provides strong fault isolation. Our prototype’s network performance is within 3–8 % of a native Linux system. Each additional virtual machine increases the CPU utilization by about 0.12%. We have successfully reused a wide variety of unmodified Linux

The X Window System

by James Gettys, Keith Packard - ACM Transactions on Graphics, Vol , 1986
"... The X Window System, Version 11, is the standard window system on Linux and UNIX systems. X11, designed in 1987, was “state of the art ” at that time. From its inception, X has been a network transparent window system in which X client applications can run on any machine in a network using an X serv ..."

Scalable TCP: Improving Performance in Highspeed Wide Area Networks

by Tom Kelly - ACM SIGCOMM Computer Communication Review , 2002
"... TCP congestion control can perform badly in highspeed wide area networks because of its slow response with large congestion windows. The challenge for any alternative protocol is to better utilize networks with high bandwidth-delay products in a simple and robust manner without interacting badly wit ..."

identically to traditional TCP stacks when small windows are sufficient. The performance of the scheme is evaluated through experimental results gathered using a Scalable TCP implementation for the Linux operating system and a gigabit transatlantic network. The results gathered suggest that the deployment

FAST TCP: Motivation, Architecture, Algorithms, Performance

by C. Jin, D. X. Wei, S. H. Low , 2004
"... We describe FAST TCP, a new TCP congestion control algorithm for high-speed long-latency networks, from design to implementation. We highlight the approach taken by FAST TCP to address the four difficulties, at both packet and flow levels, which the current TCP implementation has at large windows. W ..."

Secure Execution Via Program Shepherding

by Vladimir Kiriansky , Derek Bruening, Saman Amarasinghe , 2002
"... We introduce program shepherding, a method for monitoring control flow transfers during program execution to enforce a security policy. Program shepherding provides three techniques as building blocks for security policies. First, shepherding can restrict execution privileges on the basis of code or ..."
