				<content:encoded><![CDATA[<p>When the world&#8217;s most powerful supercomputer goes online in 2011, it won&#8217;t come pre-installed with user-friendly software applications. Not to worry! To solve that problem, <a href="http://www.greatlakesconsortium.org">The Great Lakes Consortium </a>for Petascale Computation  will spend the next three years ramping up for the world&#8217;s first sustained petascale computational system by developing new computing software, applications and technologies designed for open scientific research.</p>
<p>The Great Lakes Consortium is the result of collaboration among colleges, universities, national research laboratories and other educational institutions dedicated to the <a href="http://www.ncsa.uiuc.edu/BlueWaters">Blue Waters Project.</a></p>
<p>The Blue Waters Project, based at the University of Illinois at Urbana-Champaign&#8217;s National Center for Supercomputing Applications, will build a machine in conjunction with IBM capable of sustaining computations of one to two petaflops &#8211; computing parlance for 1 quadrillion calculations per second &#8211; on many practical scientific and engineering applications.</p>
<p>The consortium&#8217;s ultimate goal is for Blue Waters to be fully user-friendly for scientists across the country, so when it launches, it will include intense support for application development, system software development, interactions with business and industry and educational programs.</p>
<p>Iowa State University researchers Srinivas Aluru, Mark Gordon and James Oliver say they&#8217;re eager to help the scientific community step into what they call the second revolution in information technology.</p>
<p>Aluru, a Stanley Chair in Interdisciplinary Engineering and a professor of electrical and computer engineering, will direct ISU&#8217;s work with the consortium.</p>
<p>&#8220;The dramatic increase in computing capability makes this project a national asset,&#8221; he said. &#8220;A lot of money will be poured into this research. To justify public expenditure we want to be ready.&#8221;</p>
<p>The National Science Foundation is supporting the supercomputer project with a $208 million grant, said Aluru, whose research group has used supercomputing power to help with the recently concluded effort to sequence the corn genome. To do that, they developed software that uses thousands of processors to build genome assemblies in days instead of months.</p>
<p>And now Aluru is ready to make the leap to even more powerful computing. But before that can happen, researchers must work out the bugs and bottlenecks that petascale computational levels might present.</p>
<p>The issue is not just Blue Waters&#8217; peak potential, but its sustained capacity while solving problems, he said.</p>
<p>&#8220;That efficiency depends on the code we write,&#8221; he said. &#8220;We need to find the way to get higher than 70 percent efficiency on solving several challenges.&#8221;</p>
<p>Mark Gordon, ISU&#8217;s Frances M. Craig Distinguished Professor of chemistry and the director of the applied mathematics program for the U.S. Department of Energy&#8217;s Ames Laboratory, said parallel computing in chemistry, for example, has used, at most, clusters of 32-128 computers for supercomputing challenges for the past 15 to 20 years. Researchers therefore haven&#8217;t had the hands-on opportunity to work through the potential bottlenecks for using up to 100,000 clusters.</p>
<p>&#8220;It&#8217;s a whole new ballgame with new bottlenecks,&#8221; he said. &#8220;When you move toward the petascale range, we might run up against physical limitations, such as the speed of light. And the communications and data sharing issues increase by orders of magnitude. We&#8217;ll need an efficient way of communication and comparing and collecting.&#8221;</p>
<p>One of the consortium&#8217;s strategies will be forming petascale application collaboration teams or PACTS, Aluru said.</p>
<p>&#8220;Each team will work on individual problem to figure out how to use the petascale computer and avoid mistakes,&#8221; Aluru said.</p>
<p>Aluru said the Nation Science Foundation-funded project will provide two &#8220;step-up machines&#8221; along the way.</p>
<p>James Oliver, the director of ISU&#8217;s CyberInnovation Institute, said the jump to petascale computing power calls for tools such as C6, ISU&#8217;s six-sided virtual reality room that displays computer-generated images at the world&#8217;s highest resolution. He said C6 would be an ideal place to build interfaces that can display and work with all the data produced by the supercomputer.</p>
<p>Aluru said the consortium held its inaugural meeting this week to begin to lay out the technical challenges it faces. Back at ISU, Gordon said he&#8217;s waiting for word from the National Science Foundation to grant his team early access to the Blue Waters team and hardware.</p>
<p>&#8220;We&#8217;re looking forward to trying out our ideas to see if they&#8217;re going to work.&#8221;</p>

				<content:encoded><![CDATA[<p>A couple of interesting developments. First, there&#8217;s a <a href="http://science.slashdot.org/article.pl?sid=07/06/24/1739248">quantum computing gate on a chip</a>:<br />
<blockquote>
<p>After recent success in using quantum computing for superconducting qubits, researchers from Delft have formed the first Controlled-NOT quantum gate. &#8216;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&#8211;closer to what other quantum computing candidates have achieved, says physicist Hans Mooij of the Delft University of Technology in the Netherlands. Unlike today&#8217;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&#8217;s toughest coded messages and researchers to better simulate molecules for designing new drugs and materials.</p></blockquote>
<p>The special genius of a quantum computer is that it can check all possible answers to a problem and provide more or less instantaneous results. And speaking of instantaneous, here&#8217;s another major quantum development:<br />
<blockquote>
<p><a href="http://physorg.com/news101640721.html">Researchers Suggest Quantum Dots as Media for Teleportation</a></p>
<p>According to recent research, tiny clusters of atoms known as quantum dots may be excellent media for quantum teleportation, a physics phenomenon in which information â€“ in the form of a quantum state, a very specific mathematical â€œsignatureâ€ of an atom â€“ can be transmitted almost instantaneously to a distant location without having to physically travel through space. Teleportation is one facet of quantum information science, a developing field that could have a major impact on computing and communications.</p></blockquote>
<p>The quantum world is a very weird place. The rules we use in our macro world simply don&#8217;t apply there; and the rules that <em>do </em>apply there don&#8217;t make a lot of sense to us. Things like this:</p>
<p><center><object width="425" height="350"><param name="movie" value="http://www.youtube.com/v/DfPeprQ7oGc"></param><param name="wmode" value="transparent"></param><embed src="https://www.youtube.com/v/DfPeprQ7oGc" type="application/x-shockwave-flash" wmode="transparent" width="425" height="350"></embed></object></center></p>
<p>When it comes to quantum weirdness, people tend to fall into a couple of camps. The first camp is to point out that at our level of existence, <a href="http://www.amazon.com/gp/product/0465067859/104-1165339-4988747?ie=UTF8&#038;tag=thespeculist-20&#038;linkCode=xm2&#038;camp=1789&#038;creativeASIN=0465067859">the weirdness goes away</a> so we shouldn&#8217;t worry about it. The other is to try to map quantum weirdness to existing ideas about spirituality. (The video clip above is from <a href="http://www.amazon.com/gp/product/B0006UEVQ8/104-1165339-4988747?ie=UTF8&#038;tag=thespeculist-20&#038;linkCode=xm2&#038;camp=1789&#038;creativeASIN=B0006UEVQ8">a movie</a> that does the latter.) However, the two stories above suggest that maybe quantum weirdness <em>is </em>something that we&#8217;re going to have to grapple with up here in the macro world &#8212; not as spiritual phenomena but as part of the technology that takes us to a future very different from the world we live in now.</p>
