Abstract The RISC System/6000 family of products, typically based on the Microchannel bus architecture, has been expanded to include a new line of products based on the PowerPC microprocessor, the Peripheral Component Interconnect (PCI) bus architecture and the PowerPC Reference Platform Specification (PReP). The AIX Version 4.1 operating system had to be enhanced to support these new systems, and a new software layer had to be incorporated between AIX and the hardware to allow for a transparent implementation of the PowerPC Reference Platform Specification. Support for the Industry Standard Architecture (ISA) bus architecture has been added to allow for the use of the large number of ISA adapters available for personal computers. All these enhancements present new environments and new configuration tasks to system engineers, system administrators and customer engineers. This book is intended to describe this new environment and to assist the support personnel in accomplishing these new tasks.

  • Microsoft Windows NT from a UNIX Point of View 1
    Microsoft ® Windows NT™ from a Unix ® Point of View A White Paper from the Business Systems Technology Series Microsoft Windows NT ™ from a Unix ® Point of View A White Paper from the Business Systems Technology Series Abstract This paper provides a technical overview of Windows NT for the information technology (IT) professional with a strong background in Unix. It approaches the subject from the Unix point of view and relates the concepts of Windows NT to corresponding ones found in Unix. It begins with a technical comparison of the two operating systems, moves on to cover how the two can coexist in a heterogeneous environment, and finishes with a brief section describing some of the tools available to aid developers in creating applications for both platforms. About the Microsoft Business Systems Technology Series The Microsoft® Business Systems Technology Series consists of a number of interrelated white papers dedicated to educating information technology (IT) professionals about Windows NT and the Microsoft BackOffice™ family of products. While current technologies used in Microsoft products are often covered, the real purpose of this series is to give the reader an idea of how major technologies are evolving, how Microsoft is using those technologies, and what this means to IT planners. Legal Notice The descriptions of other companies’ products in this paper are provided only as a convenience to the reader. Microsoft cannot guarantee their accuracy, and the products may change over time. Also, the descriptions are intended as brief highlights to aid understanding, rather than as thorough coverage.

  • Multi-Persona Mobile Computing
    Multi-Persona Mobile Computing Jeremy Andrus Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2015 c 2015 Jeremy Andrus All Rights Reserved ABSTRACT Multi-Persona Mobile Computing Jeremy Andrus Smartphones and tablets are increasingly ubiquitous, and many users rely on multiple mobile devices to accommodate work, personal, and geographic mobility needs. Pervasive access to always-on mobile com- puting has created new security and privacy concerns for mobile devices that often force users to carry multiple devices to meet those needs. The volume and popularity of mobile devices has commingled hard- ware and software design, and created tightly vertically integrated platforms that lock users into a single, vendor-controlled ecosystem. My thesis is that lightweight mechanisms can be added to commodity operat- ing systems to enable multiple virtual phones or tablets to run at the same time on a physical smartphone or tablet device, and to enable apps from multiple mobile platforms, such as iOS and Android, to run together on the same physical device, all while maintaining the low-latency and responsiveness expected of modern mobile devices. This dissertation presents two lightweight operating systems mechanisms, virtualization and binary compatibility, that enable multi-persona mobile computing. First, we present Cells, a mobile virtualization architecture enabling multiple virtual phones, or personas, to run simultaneously on the same physical cellphone in a secure and isolated manner. Cells introduces device namespaces that allow apps to run in a virtualized environment while still leveraging native devices such as GPUs to provide accelerated graphics.
