PVFS: A Parallel File System For Linux Clusters
- 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 ..."

in parallel I/O and parallel file systems for Linux clusters. In this paper, we describe the design and implementation of PVFS and present performance results on the Chiba City cluster at Argonne. We provide performance results for a workload of concurrent reads and writes for various numbers of compute nodes
Wide-area cooperative storage with CFS
, 2001
"... The Cooperative File System (CFS) is a new peer-to-peer readonly storage system that provides provable guarantees for the efficiency, robustness, and load-balance of file storage and retrieval. CFS does this with a completely decentralized architecture that can scale to large systems. CFS servers pr ..."

the Chord location protocol, which operates in time logarithmic in the number of servers. CFS is implemented using the SFS file system toolkit and runs on Linux, OpenBSD, and FreeBSD. Experience on a globally deployed prototype shows that CFS delivers data to clients as fast as FTP. Controlled tests show
Arrakis: The Operating System is the Control Plane
"... Recent device hardware trends enable a new approach to the design of network server operating systems. In a tra-ditional operating system, the kernel mediates access to device hardware by server applications, to enforce process isolation as well as network and disk security. We have de-signed and im ..."

mediation of every operation. We describe the hardware and software changes needed to take advantage of this new abstraction, and we illustrate its power by showing improvements of 2-5 × in latency and 9 × in throughput for a popular persistent NoSQL store relative to a well-tuned Linux implementation. 1
Improving TCP/IP performance over wireless networks
- IN PROCEEDINGS, 1ST ACM CONF. ON MOBILE COMPUTING AND NETWORKING
, 1995
"... TCP is a reliable transport protocol tuned to perform well in traditional networks made up of links with low bit-error rates. Networks with higher bit-error rates, such as those with wireless links and mobile hosts, violate many of the assumptions made by TCP, causing degraded end-to-end performance ..."

Integrating Flexible Support for Security Policies into the Linux Operating System
"... The protection mechanisms of current mainstream operating systems are inadequate to support confidentiality and integrity requirements for end systems. Mandatory access control (MAC) is needed to address such requirements, but the limitations of traditional MAC have inhibited its adoption into mains ..."

into mainstream operating systems. The National Security Agency (NSA) worked with Secure Computing Corporation (SCC) to develop a flexible MAC architecture called Flask to overcome the limitations of traditional MAC. The NSA has implemented this architecture in the Linux operating system, producing a Security
FAST TCP: Motivation, Architecture, Algorithms, Performance
, 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 ..."

Scalable TCP: Improving Performance in Highspeed Wide Area Networks
- 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 ..."

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
Improving the reliability of commodity operating systems
, 2003
"... drivers remain a significant cause of system failures. In Windows XP, for example, drivers account for 85 % of recently reported failures. This article describes Nooks, a reliability subsystem that seeks to greatly enhance operating system (OS) reliability by isolating the OS from driver failures. T ..."

Nooks also tracks a driver’s use of kernel resources to facilitate automatic cleanup during recovery. To prove the viability of our approach, we implemented Nooks in the Linux
Secure Execution Via Program Shepherding
, 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 ..."

Finally, shepherding guarantees that sandboxing checks placed around any type of program operation will never be bypassed. We have implemented these capabilities efficiently
The design and implementation of Zap: A system for migrating computing environments

, 2002
"... We have created Zap, a novel system for transparent migration of legacy and networked applications. Zap provides a thin virtualization layer on top of the operating system that introduces pods, which are groups of processes that are provided a consistent, virtualized view of the system. This decoupl ..."

We demonstrate that our Linux Zap prototype can provide general-purpose process migration functionality with low overhead. Our
