They are employed to model phenomena in fields so various as climatology, quantum chemistry, compu- tational medicine, High-Energy Physics and many, many other areas. In 2 J.J. Dongarra & A.J. van der Steen this article we present some of the architectural properties and computer components that make up the present HPC computers and also give an out- look on the systems to come. For even though the speed of computers has increased tremendously over the years (often a doubling in speed every 2 or 3 years), the need for ever faster computers is still there and will not disappear in the forseeable future. Before going on to the descriptions of the machines themselves, it is use- ful to consider some mechanisms that are or have been used to increase the performance.

This photo was taken of the two pilots in the spacecraft simulator at the McDonnell plant in St. This program was the turning point in the space race with the USSR; from then on the Americans took the lead. Flights lasting two weeks, into the Van Allen Belt, the first extravehicular activities, rendezvous maneuvers and docking with other spacecraft—all of this was achieved by Gemini, paving the way for the more demanding moon landing program. The channel of the intracoastal waterway can be seen near the bottom center of the image. See all 5 - All listings for this product. McDonnell later sought to extend the Gemini program by proposing a derivative which could be used to fly a cislunar mission and even achieve a crewed lunar landing earlier and at less cost than Apollo, but these proposals were rejected by NASA. Hamilton Crawford's It was not all success, however. President Lyndon B. Like almost every significant undertaking, Project Gemini also had its dramas and tragedies. These were followed by ten flights with crews in and Any condition Any condition. First space rendezvous accomplished, station- keeping for over five hours at distances from 1 to feet 0. This mission was flown by the backup crew. Gemini was the first astronaut-carrying spacecraft to include an onboard computer, the Gemini Guidance Computer , to facilitate management and control of mission maneuvers.

The description of project management was prepared by James A. Hand and is based, in large part, upon discussions with Dr. C. Stark Draper, Ralph R. Ragan, David G. Hoag and Lewis E. Larson. Robert C. Millard and William A. Stameris also contributed to this volume.

S. A., 1972 ii The title of these volumes, “;LJI’I”s Role in Project Apollo”, provides but a mcdest hint of the enormous range of accomplishments by the staff of this Laboratory on behalf of the Apollo program. Rlanss rush into spaceflight during the 1060s demanded fertile imagination, bold pragmatism, and creative extensions of existing tecnnologies in a myriad of fields, The achievements in guidance and control for space navigation, however, are second to none for their critical importance in the success of this nation’s manned lunar-landing program, for while powerful space vehiclesand rockets provide the environment and thrust necessary for space flight, they are intrinsicaily incapable of controlling or guiding themselves on a mission as complicated and sophisticated as Apollo.

    Microprocessor History Lession MICROPROCESSORS AND MICROCONTROLLERS I 1 1947 Electronics: William Shockley, John Bardeen and Walter Brattain build the first practical point-contact transistor at Bell Labs 2 Apollo Guidance Computer (AGC) makes its debut 1960s Early Embedded System 3 Apollo Guidance Computer Designed by scientists and engineers at MIT’s Instrumentation Laboratory, the Apollo Guidance Computer (AGC) is the culmination of years of work to reduce the size of the Apollo spacecraft computer from the size of seven refrigerators side-by-side to a compact unit weighing only 70 lbs. and taking up a volume of less than 1 cubic foot. The AGC’s first flight was on Apollo 7. A year later, it steered Apollo 11 to the lunar surface. Astronauts communicated with the computer by punching two-digit codes into the display and keyboard unit (DSKY). The AGC was one of the earliest uses of integrated circuits, and used core memory, as well as read-only magnetic rope memory. The astronauts were responsible for entering more than 10,000 commands into the AGC for each trip between Earth and the Moon. 4 5 There is no consensus on who invented the IC. The American press of the 1960s named four people: Kilby, Lehovec, Noyce and Hoerni; in the 1970s the list was shortened to Kilby and Noyce. Kilby was awarded the 2000 Nobel Prize in Physics "for his part in the invention of the integrated circuit". In the 2000s, historians Leslie Berlin, Bo Lojek and Arjun Saxena reinstated the idea of multiple IC inventors and revised the contribution of Kilby.

  • NASA Study on Flight Software Complexity
    Final Report NASA Study on Flight Software Complexity Commissioned by the NASA Office of Chief Engineer Technical Excellence Program Adam West, Program Manager “The demand for complex hardware/software systems has increased more rapidly than the ability to design, implement, test, and maintain them. … It is the integrating potential of software that has allowed designers to contemplate more ambitious systems encompassing a broader and more multidisciplinary scope, and it is the growth in utilization of software components that is largely responsible for the high overall complexity of many system designs.” Michael Lyu Handbook of Software Reliability Engineering, 1996 “While technology can change quickly, getting your people to change takes a great deal longer. That is why the people- intensive job of developing software has had essentially the same problems for over 40 years. It is also why, unless you do something, the situation won’t improve by itself. In fact, current trends suggest that your future products will use more software and be more complex than those of today. This means that more of your people will work on software and that their work will be harder to track and more difficult to manage. Unless you make some changes in the way your software work is done, your current problems will likely get much worse.” Watts Humphrey Winning with Software: An Executive Strategy, 2001 Editor: Daniel L.
