Linux - Advanced Networking Overview
White Paper Besides the reliable TCP/UDP/IP protocol suite, a number of new features like firewalls, QoS, tunneling etc.has been added to the networking kernel.This document reviews these advanced networking features that have been implemented in the linux... [02 Sep 2008]
Ubuntu patches flaw
News Ubuntu became the latest Linux vendor to patch a vulnerability in the open-source operating system's kernel that could have left the door open for hackers to find their way into users' machines. Ubuntu administrators wrote in the email: "It was... [26 Aug 2008]
Canonical joins Linux Foundation
News As well as promoting Linux around the world, the Linux Foundation also sponsors the work of Linux kernel project lead Linus Torvalds. Canonical, the company that sponsors the Linux-based operating system Ubuntu, has joined the Linux Foundation. [20 Aug 2008]
Designing a Highly-Scalable Operating System: The Blue Gene/L Story
White Paper Compute nodes run a lightweight operating system called the compute node kernel. I/O nodes run a port of the Linux operating system. Compute nodes are dedicated to running application processes, whereas I/O nodes are dedicated to performing system... [04 Aug 2008]
Linux Virtual Server for Scalable Network Services
White Paper The TCP/IP stack of Linux kernel is extended to support three IP load balancing techniques, which can make parallel services of different kinds of server clusters to appear as a service on a single IP address. [04 Aug 2008]
Quality of Service on Linux for the Atlas TDAQ Event Building Network
White Paper Recent Linux releases provide QoS in the kernel to manage network traffic. The paper used PC/Linux with Gigabit Ethernet network as the testbed. The paper has analyzed the packet-loss and packet distribution for the event builder prototype of the... [17 Jul 2008]
Operating System Multilevel Load Balancing
White Paper Although sched domains implementation allows Linux to build a multilevel hierarchy to represent multilevel machines, the generic code of the current kernel version builds no more than two levels in the sched domains hierarchy. [10 Jul 2008]
Optimal Communication Performance on Fast Ethernet With GAMMA
White Paper The current prototype of the Genoa Active Message MA- chine (GAMMA) is a low-overhead, Active Messages-based inter-process communication layer implemented mainly at kernel level in the Linux Operating System. [10 Jul 2008]
Load-Balancing for a Real-Time System Based on Asymmetric Multi-Processing
White Paper ARTiS is a project that aims at enhancing the Linux kernel with better real-time properties. Unfortunately, the original load-balancing mechanism of Linux is not aware of this enhanced design. Based on the introduction of an asymmetry between the... [10 Jul 2008]
The Linux Kernel's Interrupt Controller API
White Paper This knowledge is essential when porting Linux to a custom platform: without a thorough understanding of how interrupts are incorporated into the Linux kernel, a functional embedded Linux system is not possible. [03 Jul 2008]
Audio and Gesture Latency Measurements on Linux and OSX
White Paper This paper has measure the total system latencies of MacOS 10.2.8, Red Hat Linux (2.4.25 kernel with low-latency patches), and Windows XP from stimulus in to audio out, with stimuli including analog and digital audio, and the QWERTY keyboard. [03 Jul 2008]
Linux Scalability - From the Micro to the HUGE
White Paper The author attempts to explain what scalability is as far as an operating system kernel is concerned, explain where Linux has come from and is now, and then give a possible vision for the future, as to how Linux can maintain and enhance its... [03 Jul 2008]
Trusted Path Execution for the Linux 2.6 Kernel as a Linux Security Module
White Paper The Linux Security Module project was aimed at applying security to the Linux kernel without imposing on the system. Several approaches are available to solve such a problem at the application level of a system but very few are actually implemented... [03 Jul 2008]
Real-Time Linux Kernel Design, Minimization and Optimization
White Paper Specifically, it covered the following topics: real-time operating system requirements; why the general Linux can not meet those real-time requirements; RTOS implementation approaches; mechanisms used in Real-Time Linux; skeleton code list and... [03 Jul 2008]
Improving the Linux Test Project With Kernel Code Coverage Analysis
White Paper In order to improve the quality of the Linux kernel, the authors are utilizing GCOV, a test coverage program which is part of GNU CC, to show how much of the kernel code is being exercised by test suites such as the Linux Test Project. [03 Jul 2008]
