  • Creativity – Success – Obscurity
    Author Gerry Pickering CREATIVITY – SUCCESS – OBSCURITY UNIVAC, WHAT HAPPENED? A fellow retiree posed the question of what happened. How did the company that invented the computer snatch defeat from the jaws of victory? The question piqued my interest, thus I tried to draw on my 32 years of experiences in the company and the myriad of information available on the Internet to answer the question for myself and hopefully others that may still be interested 60+ years after the invention and delivery of the first computers. Computers plural, as there were more than one computer and more than one organization from which UNIVAC descended. J. Presper Eckert and John Mauchly, located in Philadelphia PA are credited with inventing the first general purpose computer under a contract with the U.S. Army. But our heritage also traces back to a second group of people in St. Paul MN who developed several computers about the same time under contract with the U.S. Navy. This is the story of how these two companies started separately, merged to become one company, how that merged company named UNIVAC (Universal Automatic Computers) grew to become a main rival of IBM (International Business Machines), then how UNIVAC was swallowed by another company to end up in near obscurity compared to IBM and a changing industry. Admittedly it is a biased story, as I observed the industry from my perspective as an employee of UNIVAC. It is also biased in that I personally observed only a fraction of the events as they unfolded within UNIVAC. This story concludes with a detailed account of my work assignments within UNIVAC.

  • Building the Foundation Forthe Real-Time Infrastructure
    Building the Foundation for the Real-Time Infrastructure 1 Your entire business rides on the technology infrastructure you choose. So, if you’re looking to align your business’ IT operations more closely with your strategic business goals, here’s an aggressive investment opportunity that can help you start producing real, measurable results. This Executive Brief provides an overview of specific business benefits that you can expect from a Unisys standards-based, enterprise- computing environment. We help you secure your business operations so you can focus on opportunities and gain the visibility to see your business more clearly – ahead of decision points, investments, and risk. Secure Business Operations. It’s More Than You Think. Having a secure organization, meaning the ability to manage risk, is of paramount importance for most executives. And, most IT vendors offer some sort of security promise to their customers. Secure organizations are: • Confident in managing their enterprise • Trusted by their stakeholders • Positioned to enable their clients to succeed • Accustomed to exceptional performance • Able to control costs • Excellent at managing risk • Positioned for long-term competitive advantage Unisys services and technology are the foundation for the solutions you need to plan, build, run, and monitor business operations where confidence, trust, reliability, and managing risk are critical components. Gain Visibility into Your Enterprise Unisys 3D Visible Enterprise (3D-VE) is our vision for what an enterprise can become – a new way of seeing the inner workings of an organization through a virtual model of the enterprise. The result is an understanding of the cause-and-effect relationships between business vision, business operations, and the IT systems that support them – allowing you to see the results of your business decisions before you make them.

  • CISER: Cornell Researchers Team Itanium® 2-Based Unisys ES7000* Server with SAS* 9 and Windows* Server 2003 to Boost Performance and Streamline Data Center
    Intel® Business Center Case Study Business Intelligence CISER CISER: Cornell Researchers Team Itanium® 2-Based Unisys ES7000* Server with SAS* 9 and Windows* Server 2003 to Boost Performance and Streamline Data Center SOLUTION SUMMARY Challenge The Cornell Institute for Social and Economic Research (CISER) urgently needed to boost performance for processing- and memory-intensive SAS* applications. CISER needed to acquire the resources to run 64-bit SAS 9 when it became available for the Windows* Server 2003 operating system. Yet, more than 600 researchers still needed broad-ranging 32-bit support. CISER needed to find an economical way to manage both 64-bit and 32-bit user communities demanding more power. Solution Rather than continue to add 2- and 4-way servers, CISER decided to purchase a Unisys ES7000* Enterprise Server containing eight Intel® Itanium® 2 processors and 16 Intel Xeon™ processors MP. This mainframe-class machine provides tremendous processor and memory scalability in the familiar Windows environment. CISER will be able to host 32-bit and 64-bit applications in the same system while consolidating its server holdings from 12 to 1. Business value By moving to the Unisys ES7000, CISER will boost the performance of some particularly demanding SAS applications by as much as 70 percent. The additional processing power allows researchers to crunch through demanding data analyses much faster than before and to work with much larger data sets to answer questions they couldn’t even ask before. Faster answers lead to more work accomplished in a given grant period and an improved chance of renewing grant funding.

Unisys was among the first system providers to announce support for the new Itanium 2 processor 9000 series and played a major role in Intel’s announcement here today. Unisys intends to make ES7000/one servers based on the Montecito platform available in late August. Entry-level configurations of new Itanium 2 models of the ES7000/one are priced from US$45,000. The ES7000/one server powered by the new Dual-Core Intel Itanium 2 processors has demonstrated the highest performance of any 16-processor and the lowest price/performance of any non-clustered server in the 3000 GB TPC-H benchmark, widely recognized as a standard measure of system performance for decision support and business Page 1 of 3 intelligence in commercial enterprise computing.
