MathsNet: Fraction Of The Benefits On the 3rd September this year David Slowinski and Paul Gage found that 2 to thepower of 1257787 minus 1 is prime. The number has 378632 digits and took a http://www.mathsnet.net/articles/article_fraction.html
Extractions: [from the Times Educational Supplement, 29 November 1996] As the Internet revolution continues, its rate of growth alone would be a job for any mathematician. But maths teachers and students would do better to exploit the Net for gems to enliven their classes - and by making their own contributions. At Research Machines' "Internet for Learning", there's a massive list of mathematical sites, ordered alphabetically. In fact at virtually any site you will find the obligatory list of links to other recommended sites. The encyclopedic collection of all things mathematical at "Eric's Treasure Trove" took nine years to create. Theorems, facts, proofs and definitions are all ordered alphabetically, from the 15 slide-puzzle (fifteen square tablets and one space in a 4x4 grid) to Zsigmondy's theorem (something to do with prime factors). The Canadian-based "The Math Forum" includes a host of resources from schools around the country: at other sites you can find collections of puzzles, conundrums and optical illusions. There are specialist areas too. At the one on pi, you can search for your birth date in pi's decimal equivalent, 3.14159...the decimal expansion. The San Francisco Explatorium celebrates pi day every March 14th (3.14), incidentally Albert Einstein's birthday! Other sites are devoted to the Fibonacci sequence, fractals, M.C.Escher, the history of mathematics.

GIMPS At Albany It was held by David Slowinski, who has already tested more than 25000 exponents,worth about 80 P90 CPU years. Of course, he works for Cray Research, http://hawk.fab2.albany.edu/mersenne/mersenne.htm
Extractions: GIMPS at the University at Albany Since late August 1997, more than 80 PCs on faculty, staff, and student desktops and in instructional labs have become part of an experiment at Albany in distributed massively parallel processing (DMPP) if you accept 85 as "massive." If not, please check back. We're continually adding more machines. There is a three-fold purpose to this project. Firstly, we want to show that there are many idle PC cycles that can be used productively in a networked environment. Even if your screen is strewn with icons and open windows, even if you occasionally have two or three or eight Web searches going at once, even if you feel frantically busy trying to get several tasks completed, that's your sense of busy. The reality is that your processor is usually on vacation. On call, of course, but nonetheless on vacation. If you are running NT workstation on your PC, open Task Manager and click on the "Processes" tab. You will find that "System Idle" only rarely drops below 90%! That is not an argument against upgrading PCs, which is necessary in order to take advantage of 32-bit buses, large memory, huge disks, faster video cards, and everything else that new applications increasingly expect. Rather it is an argument for identifying, capturing, and using those idle cycles even if you are not the one who uses them. But that's another story.
Extractions: Advanced Circuits (established 1982) Advanced Scientific Instruments (established 1961; ceased 1964) ASI was incorporated on March 23, 1961. Its president, Francis J. Alterman, had been manager of General Mill's Digital Computer Laboratory. Prior to that, Mr. Alterman had been technical assistant to the president of Electronic Computer Corporation; the project manager for the Elecom 100 Computer; and head of the research section of W. L. Maxon Corporation. Ralph E. Mueller, ASI's executive vice president, had been a marketing representative at General Mills. He had also worked at the Aircraft and Ordnance Division of National Presto in Eau Claire, Wisconsin. ASI's first product was the Advance II, a large, fast, computer that did not require air conditioning. In 1964 ASI was acquired by Schlumberger and became EMR-Computer, with operations located at 8001 Bloomington Freeway. Source:

Le nom de Mersenne resta lier à cette classe de nombres à cause dune conjecture quil a faite en 1644. Il affirmait que les nombres de la forme (2 p - 1) sont premiers . lorsque p = 2, 3, 5, 7, 13, 17, 19, 31, 67, 127 et 257 et quils sont composés pour toute autre valeur de n inférieure à 257.

Extractions: Mercury News Computing Editor Hey buddy, can you spare a few cycles? If so, you can join ''The Great Internet Mersenne Prime Search,'' and help find some extremely large and very special numbers. Until now, finding these numbers was the province of high-powered researchers using supercomputers. This hunt, organized and launched early this year by a Florida-based programmer, employs a new kind of muscle: the collective horsepower of today's ordinary desktop personal computers plus the Internet's global reach. George Woltman, the search organizer, wanted to take advantage of the fact that PC central processors waste many if not most of their computing ''cycles'' because they don't need them to accomplish their chores in other words, they run on idle much of the time. So Woltman wrote a program that uses the PC, when it's not doing anything else, to help find Mersenne primes. Then he spread the word on the Internet, in part by setting up a special World Wide Web site, and asked for help. About 155 volunteers from around the world have signed up, and Woltman is looking for several hundred more.
Unicos.ms This paper reports an experiment in which the author and David Slowinski addeda limited version of the guest facility to Unicos, so that it can run itself http://cm.bell-labs.com/cm/cs/who/dmr/unicos.html
Extractions: Our Unicos system developers, however, valued the guest facility mainly because it simplified testing. It was possible to reboot and try new versions of Unicos merely by submitting remote COS jobs, an operation readily automated; the process took a minute or two. Although doing this required chasing away the Unicos users, they were mostly from our own organization and arrangements could be informal. In particular, rebooting Unicos did not disturb the paying customers of the computer center. Converting to native Unicos operation significantly impeded system development work; we were back in a world more normal for expensive machines, in which development takes place at most a couple of evenings per week, announced well in advance. Therefore, we decided to create a mechanism by which Unicos could support itself as a guest system. The Cray hardware does not make it possible to create a true virtual machine in the style of IBM's VM system. That is, one cannot take an arbitrary standalone operating system and create a cocoon around it so that it believes it is in sole control of the machine. However, certain aspects of the hardware, and the style in which it is used, do ease the job of running Unicos as a guest. The great advantage is that most I/O operations are done through a separate processor, the IOS, and the CPU conventionally communicates with the IOS by sending messages to it. Thus I/O operations, which are often the most problematical aspects of a VM system, are readily handled if the communication with the IOS can be intercepted and the IOS operations simulated. Another complicated aspect of a virtual machine system, paging and virtual memory, is avoided simply because the hardware doesn't support it even for native systems.

Extractions: From: davidt@usa.nai.net (David Templeton) NEW YORK August 27, 1996 IBVA Technologies, Inc., maker of the Interactive Brainwave Visual Analyzer (IBVA) system, announced today the general availability of its Video Game Control (VGC) Expansion Pak. The IBVA system is a personal computer-based electroencephalograph (EEG) featuring a one- or two-channel headband, wireless transmitter, receiver and brainwave analysis software that provides a direct mind-to-personal computer link. The new VGC Expansion Pak consists of an IBVA-enhanced arcade joystick and add-on software that enables IBVA users to use their brainwaves to wirelessly control industry standard video games running on the Sega, Super Nintendo and Sony Playstation platforms. "The combination of brainwave control technologies enhances interactivity, stimulates player interest and markedly contributes to improved player performance ... The advantage of this Pak is that normal video games can be used for brainwave interaction and control" says Drew DeVito, executive vice president with IBVA.
