Luke writes "This past winter Calvin College professor Joel Adams and then Calvin senior Tim Brom built Microwulf, a portable supercomputer with 26.25 gigaflops peak performance, that cost less than $2,500 to construct, becoming the most cost-efficient supercomputer anywhere that Adams knows of. "It's small enough to check on an airplane or fit next to a desk," said Brom. Instead of a bunch of researchers having to share a single Beowulf cluster supercomputer, now each researcher can have their own."

Shipud writes "The National Science Foundation, Public Library of Science and the San Diego Supercomputing Center have partnered to set up what can best be described as a "YouTube for scientists", SciVee". Scientists can upload their research papers, accompanied by a video where they describe the work in the form of a short lecture, accompanied by a presentation. The formulaic, technical style of scientific writing, the heavy jargonization and the need for careful elaboration often renders reading papers a laborious effort. SciVee's creators hope that that the appeal of a video or audio explanation of paper will make it easier for others to more quickly grasp the concepts of a paper and make it more digestible both to colleagues and to the general public."

eldavojohn writes "MIT's Microsystems Technology Laboratories is focusing on the manufacturing of chips as the variables that affect chip quality become more and more influential. From one of the researchers, "The extremely high speeds of these circuits make them very sensitive to both device and interconnect parameters. The circuit may still work, but with the nanometer-scale deviations in geometry, capacitance or other material properties of the interconnect, these carefully tuned circuits don't operate together at the speed they're supposed to achieve.""

eldavojohn writes "IBM has turned to long time rival Sun in an effort to bring Solaris to its mainframes. Sun may be taking this chance to drop out of the server market while at the same time capture Solaris subscriptions via IBM sales. Either way, this certainly pressures HP in the server department."

eldavojohn writes "Researchers have released a new paper on quantum computing theorizing how to use optically controlled electrons to make an ultrafast quantum computer. From the article, "Scientists have designed a scheme to create one of the fastest quantum computers to date using light pulses to rotate electron spins, which serve as quantum bits. This technique improves the overall clock rate of the quantum computer, which could lead to the fastest potentially scalable quantum computing scheme of which the scientists are aware.""

Jamie found another MIT Technology review story, this time about Chess, Supercomputing, Garry Kasparov, and trying to make sense of just what exactly it all meant when a computer finally beat a grand master. An interesting piece that touches on what it means to play chess, the difference between humanity and machinery and how super computers don't care when they are losing. Worth your time.

An anonymous reader writes "The NSF has tentatively announced that the Track 1 leadership class supercomputer will be awarded to the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. The Track 2 award winner is University of Tennessee-Knoxville and its partners." From the article: "In the first award, the University of Illinois at Urbana-Champaign (UIUC) will receive $208 million over 4.5 years to acquire and make available a petascale computer it calls "Blue Waters," which is 500 times more powerful than today's typical supercomputers. The system is expected to go online in 2011. The second award will fund the deployment and operation of an extremely powerful supercomputer at the University of Tennessee at Knoxville Joint Institute for Computational Science (JICS). The $65 million, 5-year project will include partners at Oak Ridge National Laboratory, the Texas Advanced Computing Center, and the National Center for Atmospheric Research."

An anonymous reader writes "According to documents accidentally placed on a federal government Web site for a short time last week the national science foundation (NSF) will award the contract to buy a $200M supercomputer in 2011 to IBM. The machine is designed to perform scientific calculations at sustained speed of 1 petaflop. The award is already proving controversial however, with questions being raised about the correctness of the bidding procedure. Similar concerns have also been raised about the award of a smaller machine to Oak Ridge national lab, which is a Department of Energy laboratory, not a site one would expect to house an NSF machine."

jbrodkin writes "You don't need Ivy League-type cash to get a supercomputer anymore. Organizations with limited financial resources are snatching up IBM supercomputers now that Big Blue has lowered the price of Blue Gene/L. Alabama-Birmingham and other universities that previously couldn't afford such advanced technology are using supercomputers to cure diseases at the protein level and to solve equally challenging problems. IBM dropped the price of the Blue Gene/L to $800K late last year before releasing a more powerful model, Blue Gene/P, last month. Sales of Blue Gene/L have more than doubled since then, bringing supercomputing into more corners of the academic and research worlds."

Peter Kern writes "The National Center for Supercomputing Applications (NCSA) is one of the great supercomputing facilities in the world and is home to 'Abe', one of the top 10 supercomputers on the current Top 500 list. TG Daily recently toured the facility and published a stunning report about their computing capabilities (more than 140 teraflops), power requirements (a sustained 1.7 megawatts), enormous 20-ft chillers in four cooling systems and other installations that keep the NCSA online."

Fantastic Lad writes "The US Department of Defense (DOD) may already be creating a copy of you in an alternate reality. Putting supercomputers to an innovative use, the military is simulating our planet in an effort to predict the outcome of different scenarios. They might run tests to see how long 'you' can go without food or water, or how 'you' will respond to televised propaganda. Billions of nodes are created in the system, intended to reflect every man, woman, and child. 'Called the Sentient World Simulation (SWS), it will be a "synthetic mirror of the real world with automated continuous calibration with respect to current real-world information", according to a concept paper for the project. Simulex is the company developing these systems, and they list pharmaceutical giant Eli Lilly and defense contractor Lockheed Martin among their private sector clients. The U.S. military is their biggest customer, apparently now running the most complex version of the system. JFCOM-9 is now capable of running real-time simulations for up to 62 nations, including Iraq, Afghanistan, and China. The simulations gobble up breaking news, census data, economic indicators, and climactic events in the real world, along with proprietary information such as military intelligence."

An anonymous reader writes "Researchers at University of Maryland have developed a prototype of what may be the next generation of personal computers. The new technology is based on parallel processing on a single chip and is 'capable of computing speeds up to 100 times faster than current desktops.' The prototype 'uses rich algorithmic theory to address the practical problem of building an easy-to-program multicore computer.' Readers can win $500 in cash and write their names in the history of computer science by naming the new technology."

Fletcher writes to tell us that Sun Microsystems has revealed their "Constellation System", a new supercomputing platform that the company hopes will put them back in the running for top dog in the supercomputer race. "The linchpin in the system is the switch, the piece of hardware that conducts traffic between the servers, memory and data storage. Code-named Magnum, the switch comes with 3,456 ports, a larger-than-normal number that frees up data pathways inside these powerful computers. 'We are looking at a factor-of-three improvement over the current best system at an equal number of nodes," said Andy Bechtolsheim, chief architect and senior vice president of the systems group at Sun. "We have been somewhat absent in the supercomputer market in the last few years.'"

An anonymous reader writes "ZDNet is reporting on IBM's claim that the Blue Gene/P will continuously operate at more than 1 petaflop. It is actually capable of 3 quadrillion operations a second, or 3 petaflops. IBM claims that at 1 petaflop, Blue Gene/P is performing more operations than a 1.5-mile-high stack of laptops! 'Like the vast majority of other modern supercomputers, Blue Gene/P is composed of several racks of servers lashed together in clusters for large computing tasks, such as running programs that can graphically simulate worldwide weather patterns. Technologies designed for these computers trickle down into the mainstream while conventional technologies and components are used to cut the costs of building these systems. The chip inside Blue Gene/P consists of four PowerPC 450 cores running at 850MHz each. A 2x2 foot circuit board containing 32 of the Blue Gene/P chips can churn out 435 billion operations a second. Thirty two of these boards can be stuffed into a 6-foot-high rack.'"

An anonymous reader writes "After recent success in using quantum computing for superconducting qubits, researchers from Delft have formed the first Controlled-NOT quantum gate. 'A team has demonstrated a key ingredient of such a computer by using one superconducting loop to control the information stored on a second. Combined with other recent advances, the result may pave the way for devices of double the size in the next year or two--closer to what other quantum computing candidates have achieved, says physicist Hans Mooij of the Delft University of Technology in the Netherlands. Unlike today's computers, which process information in the form of 0s and 1s, a quantum computer would achieve new levels of power by turning bits into fuzzy quantum things called qubits (pronounced cue-bits) that are 0 and 1 simultaneously. In theory, quantum computers would allow hackers to crack today's toughest coded messages and researchers to better simulate molecules for designing new drugs and materials.'"

gholmer writes "Eric Van Hensbergen reports that Plan 9 has been successfully booted on IBM's Blue Gene supercomputer. A live demo will be attempted during a poster session at this year's Usenix. There is also the obligatory Space Glenda picture."

Bob Uhl writes "I've just finished reading a review copy of O'Reilly's latest GNU/Linux title, Linux System Administration. It's a handy introduction for the beginner GNU/Linux sysadmin, and a useful addition to an experienced sysadmin's bookshelf. The book is essentially a survey of various Linux system-administration tasks: installing Debian; setting up LAMP; configuring a load-balancing, high-availability environment; working with virtualization. None of the chapters are in-depth examinations of their subjects; rather, they're enough to get you started and familiar with the concepts involved, and headed in the right direction." Read below for the rest of Bob's review.

Roland Piquepaille writes "Quantum computing is usually associated with extremely low temperatures. Physicists at Harvard University have shown that diamonds can be used to create stable quantum computing building blocks at room temperature. A nitrogen vacancy in diamond could lead to quantum registers able to store or retrieve data. '"The problem is, what makes single nuclear spin so stable - its weak interaction with its surroundings - also prevents us from directly manipulating it," Lukin says. "How do you control something that can't interact with anything?" You do it gingerly and indirectly, the Harvard physicists report in Science. They found that nuclear spins associated with single atoms of carbon-13 - which make up some 1.1 percent of natural diamond - can be manipulated via a nearby single electron whose own spin can be controlled with optical and microwave radiation.'"

An anonymous reader writes "In an addendum to the recent noises by Microsoft about Linux, InformationWeek blogger Alexander Wolfe has turned up an interesting list of who owns U.S. trademarks on the word "Linux." Yes, Linus Torvalds does indeed have the trademark as far as software is concerned. But Swiss company Rosch owns "Linux" for use with laundry detergents. Interestingly, both Pogo Linux and United Linux have abandoned their trademarks (Wolfe speculates that's because of Linus's lawyers). But Finite State Machines of New Mexico owns RTLinux and Linux Networx Inc. owns "Linux Supercomputing." You can also read the full list of all 204 Linux trademarks"

Timogen writes to tell us Wired is reporting that a research team is reporting that they have found a way to "controllably couple qubits" bringing us one step closer to quantum computing. "In classical computer science, bits -- or binary digits -- hold data encoded as ones and zeros. In quantum computing, data is measured in qubits, or quantum bits. As such, a qubit can have three possible states -- one, zero or a "superposition" of one and zero. This unique property theoretically makes quantum computing able to solve large-scale calculations that would dwarf today's supercomputers. But qubits in isolation are not very useful. It's only when they can be connected to one another that large-scale processing becomes possible."
