coondoggie quotes a report from Network World: A 17.5 foot long, 5.5 foot wide and 1.5 foot tall the 3D printed aircraft design tool has earned the title of largest solid 3D printed item by Guinness World Records. The 1,650 lb. apparatus known as a trim-and-drill tool is comparable in length to a large sport utility vehicle and will ultimately be tested for use in building the Boeing 777X passenger jet. Basically the tool will be used to secure the jet's composite wing skin for drilling and machining before assembly, according to researchers at the Department of Energy's Oak Ridge National Laboratory (ONRL) who developed the tool. "The existing, more expensive metallic tooling option we currently use comes from a supplier and typically takes three months to manufacture using conventional techniques," said Leo Christodoulou, Boeing's director of structures and materials in a statement. "Additively manufactured tools, such as the 777X wing trim tool, will save energy, time, labor and production cost and are part of our overall strategy to apply 3D printing technology in key production areas."

MikeChino quotes a report from Inhabitat: Scientists just discovered a new state of water molecules that displays some pretty unexpected characteristics. This discovery, made by researchers at the U.S. Department of Energy's Oak Ridge National Laboratory (ORNL), reveals that water molecules "tunnel" in ultra-small hexagonal channels (measuring only 5 angstrom across) of the mineral beryl. Basically, this means the molecules spread out when they are trapped in confined spaces, taking a new shape entirely. The ORNL used neutron scattering and computational modeling to reveal the "tunneling" state of water that breaks the rules of known fundamentals seen in gas, liquid, or solid state. The researchers said the discovery describes the behavior of water molecules present in tightly confined areas such as cell walls, soils, and rocks. The study was published in Physical Review Letters on April 22.

An anonymous reader quotes a report from Computerworld: The U.S. Department of Energy has demonstrated a 20,000 watt (20KW) wireless car-charging system that offers three times the efficiency of today's plug-in systems for electric vehicles (EVs). The research is the first step in creating a 50KW wireless charging system that may someday allow roadways to charge vehicles while they are being driven. The DOE's Oak Ridge National Laboratory (ORNL) in Tennessee demonstrated the new system in partnership with Toyota, Cisco Systems, Evatran and the Clemson University International Center for Automotive Research. ORNL said the 20KW charging system for passenger cars is the world's highest power wireless system. It was developed in less than three years using a "unique architecture that included an ORNL-built inverter, isolation transformer, vehicle-side electronics and coupling technologies."

hypnosec writes: Oak Ridge National Laboratory has successfully produced 50 grams of plutonium-238, an isotope that produces heat without a lot of other, problematic radiation. This makes it suitable for use in radioisotope thermoelectric generators, which can power space probes. The new sample effectively revives the U.S.'s end-to-end plutonium-238 production capabilities, which have been dormant for around 30 years since work was stopped at the Savannah River Plant in South Carolina. The ORNL is optimistic this important milestone will pave the way for regular production of the material, ensuring constant supply for NASA's future missions.

hypnosec writes "The Oak Ridge National Laboratory has unveiled a new supercomputer – Titan, which it claims is the world's most powerful supercomputer, capable of 20 petaflops of performance. The Cray XK7 supercomputer contains a total of 18,688 nodes and each node is based on a 16-core AMD Opteron 6274 processor and a Nvidia Tesla K20 Graphical Processing Unit (GPU). To be used for researching climate change and other data-intensive tasks, the supercomputer is equipped with more than 700 terabytes of memory."

1sockchuck writes "Three of the world's most powerful supercomputers live in adjacent aisles within a single data center at Oak Ridge National Laboratory in Tennessee. Inside this facility, technicians are busy installing new GPUs into the Jaguar supercomputer, the final step in its transformation into a more powerful system that will be known as Titan. The Oak Ridge team expects the GPU-accelerated machine to reach 20 petaflops, which should make it the fastest supercomputer in the Top 500. Data Center Knowledge has a story and photos looking at this unique facility, which also houses the Kraken machine from the University of Tennessee and NOAA's Gaea supercomputer."

New submitter Celarent Darii writes "Prospects for harvesting Uranium from seawater turned interesting by using shrimp shells as a sort of catalyst." Researchers at ORNL presented their findings from a test of a chitin net for harvesting Uranium at the ACS fall meeting. From the ORNL press release: "In a direct comparison to the current state-of-the-art adsorbent, HiCap provides significantly higher uranium adsorption capacity, faster uptake and higher selectivity, according to test results. Specifically, HiCap's adsorption capacity is seven times higher (146 vs. 22 grams of uranium per kilogram of adsorbent) in spiked solutions containing 6 parts per million of uranium at 20 degrees Celsius. In seawater, HiCap's adsorption capacity of 3.94 grams of uranium per kilogram of adsorbent was more than five times higher than the world's best at 0.74 grams of uranium per kilogram of adsorbent. The numbers for selectivity showed HiCap to be seven times higher."

Layzej writes "The global output of heat-trapping carbon dioxide jumped by the biggest amount on record in 2010, the U.S. Department of Energy calculated. A chart accompanying the study shows the breakdown by country. The new figures mean that levels of greenhouse gases are higher than the worst case scenario outlined by climate experts just four years ago. It is a 'monster' increase that is unheard of, said Gregg Marland, a professor of geology at Appalachian State University, who has helped calculate Department of Energy figures in the past. The question now among scientists is whether the future is the IPCC's worst case scenario or something more extreme."

An anonymous reader writes "Chemistry researchers at Oak Ridge National Laboratory say they've improved the efficiency of typical solar cells by a whopping 80% by creating a 3-D nanocone-based solar cell platform. The technology tackles the problem of poor transport of charges generated by solar photons. These charges — 'negative electrons and positive holes' — typically become trapped by defects in bulk materials and degrade performance. 'We designed the three-dimensional structure to provide an intrinsic electric field distribution that promotes efficient charge transport and high efficiency in converting energy from sunlight into electricity.' Bottom line, they say, is they've boosted the light-to-power conversion efficiency of photovoltaics by 80 percent."

brian0918 writes "Until now, the assumption has been that the rapid spin of a pulsar comes from the spin of the original star. The problem was that this only explained the fastest observed pulsars. Now, researchers at Oak Ridge have shown that the spin of a pulsar is determined by the shock wave created when the star's massive iron core collapses. From the article: 'That shock wave is inherently unstable, and eventually becomes cigar-shaped instead of spherical. The instability creates two rotating flows — one in one direction directly below the shock wave and another, inner flow, that travels in the opposite direction and spins up the core. The asymmetrical flows establish a 'sloshing' motion that accounts for the pulsars' observed spin velocities from once every 15 to 300 milliseconds.'"

FleaPlus writes "The CS Monitor reports that for the first time in 15 years a European nation has started building a nuclear reactor, with six more likely to be built in the next decade. France is also planning to develop a safer and more efficient "fourth generation" reactor by 2020. This is in light of rising fossil fuel prices and a desire to reduce CO2 emissions. Still, a majority of EU citizens are opposed to nuclear energy, primarily for environmental reasons, even though nuclear power releases less radioactive material than burning coal."

AugstWest asks: "I've been doing some research into what the available clustering options are for pooling CPU resources, and it looks like most of the solutions I've found require that programs be re-written to take advantage of the cluster. Since there are virtualization apps like Bochs and VMWare, where the applications just make use of a virtual CPU as if it was a real CPU, why aren't there clustering solutions that do this as well?"

Roland Piquepaille writes "As the recent release of the last Top500 list reminded us last month, the most powerful computers now are reaching speeds of dozens of teraflops. When these machines run a nuclear simulation or a global climate model for days or weeks, they produce datasets of tens of terabytes. How to visualize, analyze and understand such massive amounts of data? The answer is now obvious: using Linux clusters. In this very long article, "From Seeing to Understanding," Science & Technology Review looks at the technologies used at Lawrence Livermore National Laboratory (LLNL), which will host the IBM's BlueGene/L next year. Visualization will be handled by a 128- or 256-node Linux cluster. Each node contains two processors sharing one graphic card. Meanwhile, the EVEREST built by Oak Ridge National Laboratory (ORNL), has a 35 million pixels screen piloted by a 14-node dual Opteron cluster sending images to 27 projectors. Now that Linux superclusters have almost swallowed the high-end scientific computing market, they're building momentum in the high-end visualization one. The article linked above is 9-page long when printed and contains tons of information. This overview is more focusing on the hardware deployed at these two labs."

anzha writes "Cray's XT-3 has shipped. Using AMD's Opteron processor, it scales to a total of 30,580 CPUs. The starting price is $2 million for a 200 processor system. One of its strongest advantages over the std linux cluster is that it has an excellent interconnect built by Cray. Sandia National Labs and Oak Ridge National Labs are among the very first customers.

wap writes "A coal-industry sponsored group, Americans for Balanced Energy Choices thinks coal is green, and has been running television ads to make its point. The ad shows an eagle unable to fly because of smog, and then talks about how much cleaner coal is now and will be in the future, with a sub-title saying that this is because of EPA regulation. Coal burning is much cleaner now than it was due to new scrubbing technologies, but it still emits just as much carbon dioxide as ever. Carbon emissions can be reduced by increased efficiency through gasification, but the only way to stop coal from emitting carbon dioxide is carbon sequestration. Everyone agrees that sequestration is expensive, but not everyone agrees that it's even effective in the long term. Should we instead follow the suggestion of James Lovelock and go nuclear as has been discussed here before?"

Roland Piquepaille writes "The Amazon in South America is more than a forest or an habitat. It's a climate regulator which has to absorb between 200 and 300 million tons of carbon dioxide emissions produced by the 8,000 square miles of destroyed forests every year. In 1998, the Brazilian community, helped by many international institutions, launched the Large Scale Biosphere-Atmosphere Experiment (LBA). The LBA Experiment is made up of 120 projects, 61 of which are already complete. The status of these projects is currently being reviewed by 800 delegates from 170 Brazilian and foreign institutions at the III LBA Scientific Conference held in Brasilia between July 27 and 29. NASA says it plays a key role in the LBA experiment through the use of its satellites and its computer scientists. But Inter Press Service reports that the Mega-Amazon Research Project Holds Surprises -- Good and Bad: good because it provides opportunities for 400 researchers to work on postgraduate studies in the area, bad because it's still not known if the forests absorb enough carbon to compensate the emissions caused by deforestation, therefore contributing to global warming. Please read this overview for more details, references and a map of the LBA sites spanning the Amazon."

Homey R writes "As I'll be joining the staff there in a few months, I'm very excited to see that Oak Ridge National Lab has won a competition within the DOE's Office of Science to build the world's fastest supercomputer at Oak Ridge National Lab in Oak Ridge, Tennessee. It will be based on the promising Cray X1 vector architecture. Unlike many of the other DOE machines that have at some point occupied #1 on the Top 500 supercomputer list, this machine will be dedicated exclusively to non-classified scientific research (i.e., not bombs)." Cowards Anonymous adds that the system "will be funded over two years by federal grants totaling $50 million. The project involves private companies like Cray, IBM, and SGI, and when complete it will be capable of sustaining 50 trillion calculations per second."

Oak Ridge National Lab has purchased from SGI an Altix 3000 (flash movie). This article claims that: SGI Altix 3000 is recognized as the first Linux cluster that scales up to 64 processors within each node and the first cluster ever to allow global shared memory access across nodes. There is more here, here, and here.

It's the scientific achievment of our generation; what can you say about the mapping of the human genome? But here's a story behind the story. parvati turned us on to this NYT article about James Kent, who wrote the gene assembly program GigAssembler last June. It turns out that, thanks to his code, the public Human Genome Project had actually finished its work three days before the private effort by Celera Genomics -- a feather in their cap and a boon to public science. The head of Celera was "astonished" to learn of this grad student's genius -- ten thousand lines of C in a month, and why? -- "because of his concern that the genome would be locked up by commercial patents if an assembled sequence was not made publicly available for all scientists to work on." (The debate over public vs. private science continues to rage; see this Seattle P-I article, which discusses among other things the ethics of NDA'ing scientific data produced for profit.)

Update: 02/13 02:26 PM by J : Thanks to tlunde for finding the link to GigAssembler and thus clarifying which language it was written in.

This beast will have 2.5 terabytes of RAM and 50 TB of disk space."

kovacsp was the first to write to us about the announcement from Celera that they had completed mapping of the human genome. Note: This is /not/ the be-all, end-all. They have finished *mapping* one person's genes. With Celera's approach, this means that they now need to being assembling the information they've gathered. All in all, Celera plans to do the same process with four other people. The Human Genome Project, using a more traditional approach is still a couple years away, but the race is still pretty close.

Matt Ridley claims in the introduction to Genome that we are living through the greatest intellectual moment in history: the unraveling of the mystery of our own genes. He's right. This is one of the most important and hypnotically interesting books I've ever read, covering an astonishing range of issues: Why are some of us combative, friendly, hopeful, grammatical? Does free will or genetic determinism shape our behavior? Genome: The Autobiography of a Species in 23 Chapters, is the autobiography of all of us. Read more below. "Genome:the autobiography of a species in 23 chapters" author Matt Ridley pages 344 publisher Harper Collins rating 10/10 reviewer Jon Katz ISBN 0-06-019497-9 summary Uses 23 pairs of chromosomes to explain our species

There is much more to each of us than a genetic code, writes Ridley, "[b]ut until now human genes were an almost complete mystery. We will be the first generation to penetrate that mystery. We stand on the brink of great new answers but, even more, of great new questions. This is what I have tried to convey in this book."

And he's succeeded, brilliantly, even entertainingly. Genome isn't about the Human Genome Project itself, but rather about what the project is uncovering in labs all over the world. Some time this year, geneticists say they will probably have a rough draft of the complete human genome. In a short time, we will have gone from knowing little about genes to knowing nearly everything.

The human genome, the complete set of genes housed in 23 pairs of chromosomes, form Ridley's outline for what he terms an autobiography of our species. Spelled out in a billion three-letter words using only the four-letter alphabet of DNA, the genome has been altered, edited and handed down for more than three billion years. With the first human-readable draft of the genome poised on the horizon, we -- the people Ridley calls "this lucky" generation" -- are the first beings who will be able to read and ponder this profound document about what it means to be, well, us.

In Genome, Ridley picks one newly-discovered gene from each of the 23 human chromosomes and tells its story, in the process recounting some of the history of our species. Ridley weaves each chapter to be more compelling than the one before. Genes that cause disease, influence language, behavior and intelligence, genes that enable us to write grammatically, that guide the development of biology and intelligence, that permit us to remember, that relate ultimately to selfishness, hope, fate, self-interest, instinct and history.

Ridley aptly promises what he calls a "whistle-stop tour of some of the more interesting sites in the genome and what they tell us about ourselves." Some stops along that tour aren't pretty -- from the creation of Luca, the Last Universal Common Ancestor (she looked like a bacterium and lived in a warm pond) to the blood-curdling research of Nazi scientists.

Two of the most powerful chapters come towards the end -- his horrific recounting of the history of eugenics, the perverted use of genetics to breed superior humans, and his chapter on free will. This chapter raises the most elemental question when it comes to the genome, one the world has and will continue to debate: do we truly have free will, or is our behavior and fate genetically pre-determined?

Ridley's answer is both affirming and disturbing.

This is an amazing book. It's hard to imagine a more sweeping, powerful or complex subject, yet Ridley, a former science editor and reporter, has made it completely accessible, clear and comprehensible. Genetics is important to every single human being, yet few people know much about it. But in Genome, hardly a paragraph is anything but lucid. You could give it to your grandmother and she'd have little trouble getting through it, or grasping its monumental significance.

Beyond that, Ridley's great ambition for the book, declared in his preface, isn't just hype. We are, in fact, on the verge of one of the great intellectual achievements in human history. We are about to learn more about ourselves, the way we evolve, and our behavior than anybody before us has ever dared to imagine. This is a book we all urgently need to read. We are entering a new era in human knowledge and self-awareness, and few of us are really prepared for it. This book will help get you ready.

The Human Genome Project, often referred to on this site, may be the most inspiring and disturbing technological project in contemporary history. It embodies the often tragic drama of contemporary technology: well-meaning people trying in the noblest way to improve the world; setting in motion forces few ordinary people understand, agree upon or are prepared for.

The Human Genome Project may be the most inspiring and disturbing technological project ever undertaken. This is the first time we've decided in so organized a way to alter the nature of life itself.

The project is a metaphor for everything that's both right and wrong about technology: well-intentioned people are using it to try to make the world better; at the same time continuously unleashing forces we haven't fully considered or agreed upon, and can't or won't control.

During the past few years, as many Slashdot readers know, scientists all over the world have begun a coordinated, systematic effort to create a complete biochemical description of the human genome - the DNA contained in the chromosomes of human cells - and to develop a genetic map indicating which components of this genetic material determine certain human traits, from depression to disease to susceptibility to addiction to eye color or artistic ability.

The project began in l990, part of a global effort co-ordinated by the U.S. Department of Energy and the National Institutes of Health. Though its founders expected the project to last 15 years, advances in computing have accelerated the completion date; now it's only three years away. The goal of the human genome project is nothing less than to read and record the entire string of (at least) three billion letters in human DNA . According to a progress chart on the project's website, the progress towards mapping the genetics of human beings now stands at 36 per cent.

Aided by new supercomputers that analyze, store and distribute data faster that was thought possible even a few years ago, geneticists believe they have already identified the location of genes identified with dozens of disorders, including cystic fibrosis, some forms of mental retardation and Huntingdon's disease.

Supporters of the project hail it as a means of eliminating disease, emotional disorders and other forms of human suffering. But the risks and ethical dilemmas are staggering, especially considered against a backdrop of scant serious discussion anywhere in the world, certainly not in the United States.

Could employers and insurance companies obtain an individual's genetic information? Could government agencies or law enforcement authorities use genome research to invade privacy and predict behavior? Could prospective spouses demand DNA screenings to reject unsuitable mates?

Perhaps, most likely, will parents beginning using the results of genome research to begin the process of seeking out the "Perfect Baby?" To screen sperm and egg for, size, IQ, cloning, emotional and physical health?

There is no scientific consensus as to how far this project can go, or how quickly. Some geneticists have argued that the genome project is a pipedream, that the dream of unraveling the strands of human life are much more complex and mysterious than any scientific project can really grasp. But the history of genetics, supercomputing and technology all suggest that humanity is entering a new, inevitable era in the use of technology to alter human life, a direction that makes Victor Frankenstein's primitive experiments look like a crossword puzzle.

The genome project evokes a world practically bursting with technological hubris, a universe in which all children would be born healthy, and suffering would be greatly reduced. What could be nobler or more inspiring?

And there is a darker side to this radical project, even though few people in our society are considering it much. We have set out on a project whose goal is to alter the nature of human existence, without the interest of a single national political leader or a single Congressional debate (this in a country in which the mere mention of sex on the Internet sends legislative bodies into hyperdrive).

In effect, children may be given genotypes, genetic profiles. Offspring considered grotesque, revolting, impaired, repugnant or offensive could be eliminated.

How many parents will choose ugly kids when they can be assured attractive ones? Why have an idiosyncratic or rebellious offspring when you can choose a cheerful and pliant one?

Biomedical ethicist Leon Kass is one of many scientists who worry about the pace of genetic research as well as its moral consequences.

"When a couple now choose to procreate," he writes in the eighth edition of "Technology and the Future," edited by Albert Teich (Bedford/St. Martin's), "the parents are saying yes to the emergence of new life in its novelty, saying yes not only to having a child but also, tacitly, to having whatever child the child turns out to be."

Our children, he writes, are not "our" children or posessions; they aren't supposed to live anyone's lives but their own. In altering the nature of new life, parents can not only live vicariously through their offspring but completely shape their lives.

Genetic screening is only one of the moral dilemmas our culture will soon face as the result of fast-moving genetic research. Scientists and biologists are nearly unanimous in their belief that within the next decade, someone, somewhere in the world will clone the first human being.

Given the history of technological breakthroughs once this technology has been unleashed, it's a near certainty that cloning will be used to create children. The nature of technology and much of the controversy and complexity that surrounds it is that people disagree about goals. Some parents will find it noxious to bring cloned humans into the world, others will find it irresistible, even noble.

This kind of social technology - conceived with the noblest of intentions - is not containable. It has no real direction beyond the fact that skilled scientists with powerful tools want to do it. In fact, not doing it seems as inconceivable as doing it.

But we're kidding ourselves if we think the only result will be the eradictation of some diseases and human suffering. Too many people will want to use it, too much money can be made off of it. The convergence of capitalism, technology and genetic engineering will be explosive, especially in a society as technologically thoughtless as ours.

Some forms of genetic selection - rarely labeled what they actually are - are already in widespread use, from genetic screening to prenatal diagnosis. They've already raised lingering ethical questions, only infrequently disseminated by journalists, politicians or scientists.

A quarter century ago, biologist Bentley Glass wrote of "The right of every child to be born with a sound physical and mental constitution, based on a sound genotype; the inalienable right to a sound heritage."

Maybe so. But is this a universal right, or one extended only to affluent people in industrial societies with access to advanced medical technology and generous insurance plans? What about developing and Third-World nations, where few will have access to Perfect Baby technologies? What about despots and dictators who might want to use genome maps to create certain kinds of communities and nations?

Have we really thought through the implications of unleashing medical procedures that would reduce the incidence of addiction, depression, retardation and physical disabilities? Are we comfortable living in a world in which whose categories of humanity - the retarded, the blind, the disabled - will disappear from our part of the earth? Do the healthy lose something when it's possible to eradicate the impaired?

Will the rights of children really be protected, or will the ultimate result of such pell-mell, until -recently- unimaginable tinkering be a world in which people are no longer distinct from one another - a humanity that's universally attractive, intelligent, able-bodied and eyeglass-free?

If any technological project embodies the engineer/author Samuel Florman's tragic view of technology, it's the genome project.

Jules Verne and H.G. Wells are most often credited in our culture with predicting the future, but both had spotty records. Increasingly, the writers who seems to have had the clearest bead on the 21st century were Orwell, author of "1984" and Aldous Huxley, who wrote "Brave New World," both foresaw the growing social movement towards conformity and the use of technology to shape and control culture.

But even he wasn't quite far-sighted enough. He thought government would be the force most likely to peep into our bedrooms, gather information on our tastes and behavior and pressure us to dress, talk and think uniformly. In this at least, he was mistaken.

In the 20th century, the most repressive forms of government - Communism, Fascism, Apartheid, Nazism - have collapsed or been defeated. Their efforts to censor culture or employ technology to control behavior have failed.

The most powerful institutions in our time aren't evil governments but powerful corporations with billions of dollars to conduct research, gather information and shape culture and society.

Modern corporations - Microsoft comes to mind - are not intrinsically evil, and have no political or ideological goals beyond money, but they are frighteningly powerful and influential, bigger than most governments on the planet and obvlivious to their own impact on creativity, freedom and individualism.

A generation ago, who could have imagined that one company would have its software in more than 90 per cent of the personal computers in the world?

Whatever the Genome Project ultimately does or doesn't uncover, it won't be Nobel Laureates and non-profit groups that get to control it or decide how this awesome new technology will be sold and used. It will likely be corporations, the only institutions in our society with enough power to acquire and manipulate mass markets.

In a world where people who want to have kids offer attractive men and women tens of thousands of dollars for their sperm and eggs, what might people pay for the Perfect Baby? And who do you think will control and own the patents and peddle the genetic maps?

I'm sure most of you have heard about the Human Genome Project by now and how it is working to map our DNA. Aparently there is now a race going on with corporations also performing the similar experiments, except with the intent of patenting the results. Now troc is wondering if another distributed computing effort might be in order. What do you all think? Click below troc's actual question.

troc asks: "I was watching a TV programme on UK TV last night about the Human Genome Project and how there was a race to sequence and publish the whole thing before the private companies do it and patent the sequences. Basically lasers are used to break up the strands, these are then read and fed into a computer that tries to match the bits up with other bits like a giant jigsaw puzzle. This requires a lot of computing time.

Is this an opportunity for the open source movement to help decode the sequences and publish the whole thing becore it's patented?

<soapbox>

I, for one, don't like the idea of a private company owning my gene sequences. They will be able to limit the use of these so only really rich pharmaceutical companies will be able to develop drugs etc and then sell them at huge profits, which isn't realy for the benefit of mankind blah blah blah.

</soapbox>"

I agree. I don't see how information like this can be patented. There is nothing truly proprietary about it, and it would do more good in the public where the benefit can truly be felt.

The name Beowulf stems from an old English tale and was the name of the first e xample of this class of computers. In fact a Beowulf is nothing else as a local computer network. You might say I have a small network in my flat (f.e. an old 486 connected to my newer machine), do I have a Beowulf? The answer is yes. Yo u do own already the hardware to start. Even if your connection is via PLIP/SLI P you can call your construction a Beowulf as soon as ping is successf ul. Forget all the hype about expensive special networking stuff like switches, Myrinet or SCI. For some tasks it is helpful but others won't benefit. A 10/10 0Mb connection seems to be sufficient for serious starting.

A Beowulf is not a solution for all of your speed problems. Building a Beowulf has not the same effect as f.e. the increasing of clock speed. With a Beowulf y ou won't see a speedup of your daily software and the class of software that is already adopted to Beowulfs can have very different speedups.

The hardware part is nothing more than connecting PCs with standard networking hardware. The main idea is to make your PCs to talk to each other. The most com mon solution is message passing. There are two main ways for doing message pass ing: PVM and MPI. The decision between them is mainly a matter of taste (see here for a comparing paper). I will foc us on PVM but keep in mind that MPI is as good. You can get that stuff here. The pvm3.x.x.tar.gz package has a long history and is rock solid stuff. Sinc e 1993 I did install it on half a dozen unices and never met a major problem. A fter unpacking and compiling play around (yes there is a "hello world" example) . After playing with the examples. You will see that the main commands are pvm_ send and pvm_receive and If you think that you do understand the examples start your own programming If you know what matrix multiplication is, try to impleme nt a parallel version. This is an instructive example. If you have problems you may ask for a debugging utility. Try to get xpvm-1.2.5.tar.gz from the above U RL. Its not a debugger but it visualises the behaviour of your parallel code. T he whole thing may take you two or three evenings. After that you know the basi cs of the Beowulf concept of making a pile of PCs looking as one machine.

Now you may have some questions:

Q: Sounds interesting, but I don't have a network at home. What can I do?
A: You have a network (the loopback device) in your Linux box. This means that you can install PVM/MPI and play with it. Of course you won't see a speedup. :-(

Q: I have access to a computer pool but I'm only a common user.
A: You don't have to be "root". You can install PVM/MPI as a normal user and tr ansform this pool in your personal Beowulf.

Q: I'm not a C programmer, but I use [Perl|Tcl|Python]?
A: There are interfaces available at the PVM home page (MPI??).

Q: Im not a programmer. Are there interesting applications?
A: Im sure there are plenty of applications that exploit the power of Beowulfs. Most of the stuff lives in academic environment and this means that availabilit y and quality differs. I use f.e. GAMESS a quantum chemistry program that uses MPI. Maybe one appl ication need's to be specially mentioned. There are two Beowulf-ready patches f or the famous POVray ray-tracing program. PV MPOV is more flexible but less robust and FLY3 is robust but a little inflexible. If you use POVray very o ften and play with the idea of buying a PII[34]00 MHz you may rethink this idea if you checked the povbench res ults at The fastest rendering was done with a messa ge passing version of povray.

Q: If you state that building and using of Beowulfs is that easy why aren't the re more Beowulfs?
A: I don't know why there aren't more, but I think this situation will change.

Q: I'm a little confused about the many packages that allows computing of Beowu lfs?
A: Indeed there is a whole zoo of packages for programming networked workstatio ns. For a first attempt you don't need them but some of them solve special prob lems. For an overview about the important ones check out the "Linux Parallel Pr ocessing HOWTO" by Hank Dietz.

Q: Is there a PVM/MPI version for Windows95?
A: Yes there are Win32 versions of PVM and MPI, but who cares. In fact every (pseudo)multitasking operating system with network support can in principal be used to build a Beowulf (f.e. there is Win 3.x port for PVM).

Q: Where can I get more Information?
A: As you may have seen from the above the message passing part is the stuff th at is tricky. You find links to books and tutorial for parallel programming on the PVM/MPI home pages. Hardware related information at introductory level you will find in the "Beowulf HOWTO" by Jacek Radajewski and Doug Eadline. A comprehensive overv iew on hardware and software in the "Linux Parallel Programming HOWTO" by Hank Dietz.

Q: Do I need the Beowulf software packages from the Beowulf project at NASA?
A: If you use Linux, then you probably use one of the network driver developed by Donald Becker. So the Beowulf project is already at your home and in this se nse necessary. The rest of NASA's Beowulf software provided for the use with cl usters helps you to manage a large cluster but it's not necessary and probably not the first step to do and beyond the scope of a quickstart. Even the suits a t NASA have realized that Beowulfs are a powerful tool, but the shutdown of the Beowulf web pages is like preventing the production of cars by closing a horn factory.

Q: If you can connect local PC's to look as one computer, why not coupling comp uters via Internet to a supercomputer?
A: Standard message passing software uses communication protocols that are very sensitive to packet loss. But there are activities in this area. Look for the keywords "metacomputing" or "hypercomputing".
