White Paper: Total cost of ownership Linux vs. QNX – Part 1

Is there such thing as a free OS? In this white paper we examine the total cost of ownership of an open source operating system vs. a commercial operating system.

White Paper: Tuning HPEC Linux Clusters for Real-Time Determinism

This paper investigates interrupt response times and message passing latencies using OpenMPI on three different versions of the Linux kernel; one ‘standard’ server grade, one server grade with real-time pre-empt patches applied, and one with a proprietary, real-time kernel. In order to characterize these platforms, a series of measurements were made with and without a background CPU load.

White Paper: Using Linux in Medical Devices: What Developers and Manufacturers Need to Know

Linux is a popular choice for a wide range of medical devices. Yet due to the critical nature of these devices, manufacturers must take additional precautions. This paper explores the issues that software developers and medical device manufacturers need to take into account in choosing Linux for medical devices. It outlines some regulatory compliance and support requirements for software in medical devices and what to look for in a commercial Linux vendor. It highlights how Wind River addresses these issues by providing a comprehensive solution, including the necessary documentation, services, and support to help build high-performance devices.

RDMA: The Future of High-Speed Fabric Interconnects

This white paper will explore the merits of InfiniBand architecture as well as methods of optimizing its use.

White Paper: Switched Fabrics Support High-Performance Embedded Computing for Military and Aerospace Platforms

Lessons learned from high-performance computing arena can be transferred to military and aerospace applications for improved component interoperability.

White Paper: Consumer Market Drives Advances in High-Performance Embedded Computing

Military and aerospace sector reaps benefits from consumer-led technology developments. The military and aerospace market may be said to have started this situation, first as far back as the late-1970s with the Advanced Research Projects Agency Network (ARPANET) that laid the groundwork for the packet-switch networks that, in turn, form the basis of today’s Internet, then again with the 1980s Very High-Speed Integrated Circuits (VHSIC) program that established the blueprints for semiconductor design and manufacturing.

White Paper: PCI Express Peer-to-Peer Interconnect

PCIe as a backplane fabric: The system architecture implications.

White Paper: MontaVista Linux Carrier Grade Edition

The adoption of Linux in the communications network infrastructure space is very evident. A carrier grade operating system platform brings tremendous benefits for the entire service life of a deployed system, but, as they say, “getting there can be half the battle.” Getting the system developed and debugged for deployment in time for the market window is essential. The quality and depth of the development tools available have a big impact on an organization’s ability to design, implement and test an application quickly and efficiently.

White Paper: Beyond Virtualization: The MontaVista Approach to Multi-core SoC Resource Allocation and Control

This paper outlines an approach to using a number of known Linux technologies to deliver a highly configurable, scalable, and virtualized Linux environment that includes a very low overhead run-time capability that can match bare-machine and/or RTOS performance.

White Paper: MontaVista Linux 6: Streamlining the Embedded Linux Development Process

One of the great strengths of open source software is the thriving and varied community of developers and software and the many alternatives this presents. However, a developer can invest many man-hours investigating the best
solution for a particular development environment. In fact a substantial amount of time can be spend merely understanding what the alternatives are. A developer on an embedded Linux project can waste a great deal of time simply surveying and selecting from the available components.

White Paper: MontaVista Linux Carrier Grade Edition

One example is enough to illustrate the potential impact network failures can have. In 1991, a packet-switched network failed. This failure caused hundreds of millions of dollars in financial losses, knocked out air traffic control in the New York City region for over 8 hours, and disrupted 85,000 travelers.

Building communication networks that are reliable and perform well is economically and technically challenging: the physics, the finances, and the computing are often state-of-the-art.

White Paper: Executive speakout: The new Linux supply chain

Downloading source and building a Linux distribution (“Roll-Your-Own,” or RYO) provides the most flexibility, but requires a tremendous amount of work to integrate all the required components.
