whitepaper Local Temperature Control in Data Center Cooling: Part II, Statistical Analysis2006-05-02 06:22:14 Hewlett-Packard
  The data center plays a more and more important role with the increasing demands of internet and commodity computing. As a result of the evolution of the microprocessor and increasing demands of customers, the power density in data centers becomes much greater. Mechanical engineers face challenges in cooling system design. Recent research focuses on local control algorithms which can help to optimize local temperature distribution, and thus increase the energy efficiency of the system. This paper analyzes the relationship between rack inlet temperature and vent group configuration from the view of statistics. It also examines whether rack power can affect inlet temperature.   
whitepaper Local Temperature Control in Data Center Cooling: Part I, Correlation Matrix2006-03-06 Hewlett-Packard (HP)
  A data center is a computer room containing a dense aggregation of commodity computing, networking and storage hardware mounted in industry standard racks. With the evolution of microprocessor fabrication technology and the increasing demand of internet, power density has been growing from the chip level to the data center level. As a result, mechanical designers face the challenge of handling heat dissipation efficiently in a data center. This paper demonstrates the possibility of optimizing local temperature distribution using vent tiles. In the proposed experiments, the relationship between rack inlet temperature and vent tile configuration is analyzed, and used to demonstrate the effectiveness of a local control algorithm through a control simulation.

whitepaper Energy Per Instruction Trends in Intel Microprocessors2006-03-06 Intel
  Energy Per Instruction (EPI) is a measure of the amount of energy expended by a microprocessor for each instruction that the microprocessor executes. This paper presents an overview of EPI, explain the factors that affect a microprocessor's EPI, and derive a historical comparison of the trends in EPI over multiple generations of Intel microprocessors. It shows that the recent Intel Pentium M and Intel Core Duo microprocessors achieve significantly lower EPI than what would be expected from a continuation of historical trends.

whitepaper Achieving High-Resolution Video Using Scalable Capture, Processing, and Display2006-02-28 Hewlett-Packard (HP)
  New video applications are becoming possible with the advent of several enabling technologies: multicamera capture, increased PC bus bandwidth, multicore processors, and advanced graphics cards. This paper presents a commercially-available multicamera system and a software architecture that, coupled with industry trends, create a situation in which video capture, processing, and display are all increasingly scalable in the number of video streams. Leveraging this end-to-end scalability, the authors introduce a novel method of generating high-resolution, panoramic video. While traditional point-based mosaicking requires significant image overlap, authors gain significant advantage by calibrating using shared observations of lines to constrain the placement of images.

whitepaper Systems Research Challenges: A Scale-Out Perspective2006-02-22 IBM
  The dominant programming model for such systems consists of message passing at the systems level and multithreading at the element level. Today, exploiting scale-out at all levels in systems is becoming imperative in order to overcome a fundamental discontinuity in the development of microprocessor technology caused by power dissipation. The pervasive use of greater levels of scale-out, on the other hand, creates its own challenges in architecture, programming, systems management, and reliability. This paper identifies some of the important research problems that must be addressed in order to deal with the technology disruption and fully realize the opportunity offered by scale-out.

whitepaper All Aboard!: The New Intel-Based Mac Is Leaving the Station; Here's How to Switch Platforms2006-02-17 Integration New Media
  One can expect Apple to release in the not-too-distant future a product line of smaller, faster, lighter computers with extended battery lives. Portable computing is the fastest growing segment of the mainstream market and Apple's latest move launches it to the head of the pack. Fortunately or unfortunately, that leaves software developers scrambling to keep up - not only with Apple's technology but with the increased product demand that will inevitably follow this move. This paper offers up some suggestions and strategic solutions to help you jump on board the Intel-Apple train and not get left behind on the platform.

whitepaper End-User Reasons for Buying HP Integrity Servers2006-02-01 IDEAS International
  As its customers are well aware, Hewlett-Packard's (HP) strategic server direction involves moving its platforms away from proprietary processors to new designs based on industry-standard chips. For customers seeking premier performance and enterprise-class reliability, HP employs Intel's Itanium processors in its HP Integrity server product line. To showcase the successes of those users who have already moved to Integrity servers, HP engaged Ideas International (IDEAS) to interview a sample of Integrity users around the world and prepare a summary of customer perceptions. In early 2005, IDEAS spoke with a number of early adopters of Integrity servers to understand why they selected this Itanium-based server family and why they would do so again in the future. This paper summarizes their viewpoints.

whitepaper Clarifying HP NonStop Server New Terminology2006-01-01 Hewlett-Packard (HP)
  As computer systems evolve, so does their terminology. HP NonStop servers have always had their own set of terminology, partly as a result of being on the leading edge in developing new technologies. The use of NonStop system - specific terminology continues to make sense for features that are unique to these systems, but can also lead to problems when trying to explain more industry-standard attributes to potential customers or other audiences less familiar with NonStop terminology. This white paper provides a "decoder ring" of sorts for mapping the new terms that you may encounter in reading about these systems to counterpart NonStop server classic terminology.
