whitepaper Real-Time Capabilities for Linux SGI REACT Real-Time for Linux2007-02-01 SGI
  This white paper describes the real-time capabilities provided by SGI REACT Real-Time for Linux software. REACT enables SGI Linux-based system platforms to deliver Hard Real-Time (HRT) capabilities including an interrupt response time of 30us or less. A brief review of current real-time Linux capabilities, a description of typical real-time applications, and a comparison of SGI real-time capabilities for Linux versus IRIX are also included.   
whitepaper Experimental Evaluation of Cubic-TCP2007-01-29 National University of Ireland, Maynooth
  This paper presents an initial experimental evaluation of the recently proposed Cubic-TCP algorithm. Results are presented using a suite of benchmark tests that have been recently proposed in the literature, and a number of issues are of practical concern highlighted. While some of these issues may be considered minor (including questions surrounding transient cwnd fluctuations), a number are of significant concern. Amongst these, the issue of slow convergence that is a feature of Cubic-TCP, and of other algorithms, seems most worrying. Consideration of the Cubic algorithm is particularly topical in view of discussions regarding its adoption in Linux.

whitepaper Extending Linux for Multi-Level Security2007-01-22 IBM
  Linux distributions have received numerous Common Criteria certifications in the last few years. Building on the recent Controlled Access Protection Profile (CAPP) certifications, an Open Source development effort to make Linux compliant with the Labeled Security Protection Profile (LSPP) and Role-Based Access Control Protection Profile (RBACPP) has been ongoing for almost two years. Development included adding and augmenting features of SELinux and other Linux components. This paper explores the evolution of, and rationale behind, the features developed to meet LSPP and RBACPP, and it discusses the current state of development and lessons learned.

whitepaper Secunia Vulnerability Study: Summary and Analysis2007-01-15 Microsoft
  This paper compares the security of Red Hat Enterprise Linux ES 3, Red Hat Enterprise Linux ES 4, and Microsoft Windows Server 2003 Enterprise Edition. Different aspects of operating system security, such as number of vulnerabilities and the time to resolve them, were analyzed as indicators of security for each operating system.

whitepaper Linux Kernel Development2007-01-09 University of Waikato
  This paper gives a brief overview of the author's research into network protocols and then focuses on the process of development for the Linux kernel. This topic is approached both from a technical viewpoint and also the interactions with the open source community. The aim of the paper is for readers not to have the same difficulties the author experienced!.

whitepaper Real-World Performance of SUSE Linux Enterprise Real Time2007-01-01 Novell
  "Real Time" means different things to different people. For the purposes of this paper, real time is the ability to complete a task within a predetermined length of time - every time that task is performed - regardless of external stimuli. This paper documents the excellent results of several proof-of-concept exercises conducted with database and financial applications using SUSE Linux Enterprise Real Time. It also includes specific results of real-time tests comparing the PDL times of SUSE Linux Enterprise Real Time with Red Hat and other Linux kernels. PDL numbers are good indicators of how deterministic an operating system is. The lower the PDL number, the better real-time performance can be expected from a system in the real world.

whitepaper Deploying Oracle Application Server 10g on Dell PowerEdge Servers With Linux2007-01-01 Oracle
  This paper discusses the architectural options for Oracle Application Server 10g. Oracle Application Server can be deployed in a variety of different topologies allowing individual components to be distributed across multiple servers, or to be duplicated in a clustered configuration. This provides benefits both in terms of application performance and High Availability. Due to this flexibility, Administrators are faced with a large number of architectural and deployment decisions for an Oracle Application Server 10g implementation. This paper examines a variety of deployment options including two-tier, three-tier, and multi-tier topologies. The main focus of this paper is to provide a step-by-step deployment guide for installing Oracle Application Server 10g on the Red Hat Linux Operating System with Dell PowerEdge Servers and Dell/EMC storage.

whitepaper Embedding Open Source2007-01-01 Oracle
  Oracle's role in open source development has been a well-kept secret. It's also the reason for this column: To inform the user about Oracle's commitment to open source software - a commitment measured by significant investments in ongoing development and support across a wide variety of initiatives. As ever, Oracle is driven by customer demand for choice, flexibility, and a lower cost of computing. In addition to contributing to many open standards and creating products that implement those standards, Oracle invests significant resources in developing, testing, optimizing, supporting, and contributing to open source technologies such as Linux, PHP, Apache, Eclipse, Oracle Berkeley DB, and InnoDB.

whitepaper The Lock Hold Time Prediction of Non-Preemptible Sections in Linux 2.6.192007-01-01 Korea Advanced Institute of Science and Technology
  This paper proposed a new technique, called a Delayed Locking Technique (DLT), to improve the real-time performance of General-Purpose Operating Systems (GPOSs). The proposed technique employs the rule that entering a critical section is allowed only if the operation does not disturb the future execution of the real-time application. To execute this rule, lock hold time prediction is necessary. This paper runs four heavy workloads, tcp_sender, tcp_receiver, malloc_stress, and fork_stress, on Linux 2.6.19 and attempted to identify a set of long non-preemptible sections. As a result, they found 58 relatively long non-preemptible sections and measured the lock hold time of each section under the workloads.

whitepaper Olly! (OnLine Learning for You!): Browser Based Instant Messaging for Online Learning2007-01-01 Victoria University
  This paper outlines the design principles and software architecture of Olly! (OnLine Learning for You!). Olly! is an open source, browser based instant messaging tool designed specifically for conducting classes online. Built on the AJAX scripting model, it is crossbrowser compatible and universally available to anyone with access to a computer. Data generated by the tool (text based conversations, file uploads, etc.) is retained by the institution offering the service. While currently a prototype, the future development of Olly! will produce a release candidate for use in a variety of online learning applications.
