whitepaper SUSE Linux Enterprise 10 SP1: Virtualization Technology Support2007-06-01 Novell
  SUSE Linux Enterprise Server 10 provides integrated Xen-based virtualization, which can be used to provision, de-provision, install, monitor and manage multiple Virtual Machines (VMs) on a single physical system. Out of the box, it can create VMs running both modified, highly tuned, paravirtualized operating systems and unmodified operating systems. Xen serves as the hypervisor, or VM monitor. It is a layer of software that runs directly on the server hardware and controls platform resources, sharing them among multiple VMs and their operating systems by presenting virtualized hardware interfaces to each VM.

whitepaper An Efficient Snapshot Technique for Ext3 File System in Linux 2.60000-00-00 Pohang University of Science And Technology
  Snapshot is to create an instant image of a file system. Creating a snapshot image with little processing and space overheads is critical to provide the continuous data service during backup. In Linux, there are two types of snapshot techniques available: volume-based approach like Logical Volume Manager (LVM) and le system-based approach like SnapFS. The volume-based LVM provides efficient space management capability, but requires some space to be exclusively reserved to store snapshot images and results in high snapshot processing overhead. This paper develops a file system-based snapshot for the ext3 le system in Linux kernel 2.6. The main concept of the file system-based snapshot mainly comes from old-version SnapFS. Experimental evaluation shows that the implementation is quite efficient and working correctly.

whitepaper Introducing the C-API Simulink Target for RT-Linux0000-00-00 University of Navarra
  The C-API Simulink Target for RT-Linux (CAPI STRTL) is an application developed to extend the functionality of the original Simulink Target for RT-Linux (STRTL) by providing the user with full parameter tuning and signal access, of a real time application running in a RT-Linux kernel, independent of the Simulink/MATLAB interface. In this manner, CAPI STRTL extends the utility of the original STRTL from its conventional use in control applications to more exotic fields such as haptics/virtual reality and even augmented reality - not to mention the many other possible implementations users can realize by having signal access and parameter tuning at the disposal of their custom applications.

whitepaper Implementation of Real-Time Virtual CPU Partition on Linux0000-00-00 University of Texas
  A real-time virtual resource is an abstraction for resource sharing where the application task groups sharing a resource must meet timing constraints in the absence of knowledge of all the timing requirements of all the task groups, thus prohibiting a global schedulability analysis. RTVR addresses the issues of application isolation in the open system environment, as well as satisfying the timeliness requirements of all the task groups. Based on the theoretical framework in previous work, this paper presents the first implementation of a real-time virtual resource for the CPU. This paper describes two RealTime Virtual Resource (RTVR) prototypes that are based on the Linux 2.4.18.3 kernel.

whitepaper Driver Architecture in a Linux World0000-00-00 LVL7 Systems
  Vendors of modern networking hardware realize that the devices they provide require a great deal of software in order to function effectively. As a result, many hardware vendors provide large amounts of software for use with their devices. This paper begins by discussing strategies for making use of such drivers in a Linux environment, and continues by discussing how hardware vendors might architect Linux-friendly driver software. Finally, the paper discusses how vendors can provide first-class Linux support for their hardware and why it is in their best interest to do so. This paper is a must read both for system integrators new to Linux and for driver software architects unfamiliar with the Linux environment.

whitepaper Development of Robot Controllers Based on PC Hardware and Open Source Software0000-00-00 LinuxDevices.com
  Researchers, developers and system integrators require more openness in control systems in order to design, develop and rapidly integrate functionalities to fulfill new application requirements. Even if several robot control vendors provide their products with customized development tools, low cost and not proprietary solutions should be preferred to face the rapid market changes and to reduce control life cycle costs. In fact, most important success factors are the use of off-the-shelf hardware and open source and/or free software, as well as a design focused on reconfigurability and portability of the control software is crucial. In this paper a control architecture which complies with the above mentioned requirements is presented.

whitepaper Embedded Real Time Linux Kernel Design Using Game Theory and Control Logic0000-00-00 Cornell University
  This paper describes a distributed hybrid architecture that imparts autonomous intelligence capabilities of the "Perception-decision-action" to an ALV (Autonomous Landing Vehicle) control unit. The system is shown to degenerate to a remote thread execution mechanism of a real-time operating Linux system where the kernel instantiation is control strategy dependent. This section deals with some of the quantization aspects of the control system architecture.

whitepaper Soft Real-Time Linux Overview0000-00-00 Vienna University of Technology
  As real-time capabilities are becoming relevant in main-stream desk-top Linux more and more, and new variants and ideas are popping up all over the Open-Source world, a notoriously incomplete, overview of the existing variants of soft-real time Linux is given in the paper. Many of the variants are for special purposes, some are more general approaches that target every-day soft-rt demands, like audio/video streaming, finding the way through the many approaches and selecting the one that best fits the problem is not always easy, this paper hopes to clarify a few basic terms and technological concepts, in the hope that it will simplify this selection process.

whitepaper The Real-Time Driver Model and First Applications0000-00-00 University of Hannover
  The Real-Time Driver Model (RTDM) is an approach to unify the interfaces for developing device drivers and associated applications under real-time Linux. The device models supported by RTDM will be introduced in this paper. An overview of the low and high level APIs will be given and the concept of device pro les for defining generic device interfaces will be presented. Moreover, the integration of RTDM in Xenomai will be explained and a survey of already available applications of this concept will be provided.

whitepaper LAMP on SUSE Linux Enterprise2007-05-01 Novell
  The LAMP stack of open source software components - Linux; the Apache Web server; MySQL database; and the coder's choice of PHP, Python or Perl - has moved beyond its position as a Web developer's creative toolkit to become a major development platform for the enterprise. Long a cornerstone of the Web's highest volume sites (including Amazon, Friendster, Google and Yahoo), LAMP has more recently been used to create major online transactional systems for Boeing, Disney, Lufthansa and Sabre, to name only a few organizations. What these bellwethers of online business have discovered is that open source software now offers the simplest, fastest, most flexible, affordable and scalable platform for building and deploying Web-based, enterprise-class applications.
