Flops aren't everything. Sometimes what a researcher really needs is a computing system that can also do lots of iops. And systems that use solid state drives just might fit the bill. iSGTW spoke with a variety of experts to get the facts about solid state drives in grids and high-performance computing. Hear from Richard Moore and Allan Snavely of San Diego Supercomputer Center; Shawn McKee, Rob Gardner, and Dan Fraser about Open Science Grid; and Peter Solagna of the European Grid Infrastructure.

New computing tools could save graduate students from thousands of hours spent visually inspecting historical maps, quilts, medieval art, and manuscripts.

Humanities researchers use laborious visual inspection of historical materials to determine authorship and artistic lineage for manuscripts, maps, and quilts. A typical research project could take the time of several graduate students two or more years.

“We are interested in understanding how to support these domain scientists so they are more efficient,” said Peter Bajcsy, principal investigator for the Digging into Image Data to Answer Authorship-Related Questions (DID-ARQ) project at the National Center for Supercomputing Applications. He added, “We are giving them tools that will automate the visual inspection process.”

Those tools are the product of extensive collaboration between humanities researchers and Bajcsy’s team. To create them, the computer experts engaged in lengthy discussions to determine what questions the humanities researchers seek to answer, and exactly how they would answer them using traditional methods. Their inquiries sought out details such as which image features researchers use – consciously or unconsciously – to identify the author or artist. Then the computer scientists developed algorithms that could rapidly identify those features automatically.

All Greek universities get their internet from one source: GRNET (Greek Research and Education Network), a company supported by the Greek state, which connects them both to each other and to the larger pan-European academic network, GÉANT.
GRNET’s mission is to get universities on line, to provide computing power and storage, and to develop services for researchers. Not the least of which is providing technical know-how and supporting schools and universities in Greece. “GRNET is actually a human network — this is the most important thing about it,” says Kostas Koumantaros, member of GRNET in Athens. “We transfer know-how between universities throughout Greece. It is a good vehicle to both promote research in Greece and for us to learn from our international collabora

Occasionally, iSGTW runs across stories in other publications related to the fields we cover. Below is an excerpt from Linux Journal, containing one person’s view of the whole process.
One of the items at the heart of the Large Hadron Collider (LHC) experiments is open-source software. The following will provide a glimpse into how scientific computing embraces open-source software and its open-source philosophy.
The LHC at CERN near Geneva, Switzerland, is nearly 100 meters underground and produces the highest-energy subatomic particle beams on Earth. The Compact Muon Solenoid experiment is one of the many collider experiments within the LHC. One of its goals is to give physicists a window into the universe fractions

Image courtesy Freek Dijkstra Researchers from Holland have demonstrated a network infrastructure that could potentially help scientists save time and even transform the movie business. This could be done without the need for large computer clusters or grids, just off-the-shelf hardware components combined with human ingenuity and one of the world’s fastest research networks. The team were from SARA, a Dutch supercomputing and e-science support center. Threshold The SARA researchers wanted to show the practicalities of streaming video between two institutions (from SARA, Amsterdam to CERN, Geneva) at 40Gb/second (5GB/s). This link, if successful, would be 16 times faster than the TEIN3 network, which streamed Malaysian dancers over 9,000 kilometers away to a live orchestra performance in Stockholm at 2.5 Gb/s. Th

Feature - Rethinking scientific data management

Despite all the good that science has wrought over the years, the way we manage scientific data is fundamentally flawed.
Sir Isaac Newton once said, “If I have seen further it is only by standing on the shoulders of giants.” Scientists stand on the shoulders of their peers and predecessors via peer-reviewed literature. The idea is that the literature is reliable by dint of being peer-reviewed, and thus researchers can safely build upon what they learn from it. Yet neither the reviewers who admitted those papers into the annals of scientific canon nor the scientists who wish to build upon it have access to the data used to produce those papers.
That means that they cannot ensure that they stand on solid ground by examining the data and doing their own analysis. They cannot analyze the data using altern

Dan Hooper and Lisa Goodenough are not part of the Fermi Gamma-ray Space Telescope collaboration. But by using FGST’s publicly released data, they were able to find clues to some of the universe’s juiciest secrets at the center of the Milky Way.
In their analysis, Hooper, a Fermilab theorist, and Goodenough, a graduate student at New York University, report that very-high-energy gamma rays coming from the center of the Milky Way originate from dark-matter collisions.
“We went out of our way to consider all causes of backgrounds that mimic the signal, and we found no other plausible astrophysics sources or mechanics that can produce a signal like this,” Hooper said.
A recent paper, published on the pre-print server arXiv, outlines their findings.
Astrophysicists have long postulated a wide range of

Feature - New physics in space

New life was breathed into the International Space Station (ISS) this year after NASA announced it will extend the ISS from 2015 to at least 2020.The new deadline extends opportunities for science experimentation in the largest space research laboratory ever constructed. One of these experiments is the Alpha Magnetic Spectrometer (AMS-02), a detector that may help scientists understand why our universe exists and why there is more matter than anti-matter.Most space-grade electronics are about ten years old, so the AMS-02 represents the newest and most advanced physics experiment in outer space to date. Currently, it is being tested and due to launch in February 2011. AMS-02 was shipped via Geneva airport to NASA this August in one of the largest planes in the world, a US Air Force C5 Super Galaxy.Once aboard the ISS, A

The Large Synoptic Survey Telescope to be constructed in Chile will incorporate the world’s largest digital camera, capable of recording highly detailed data more quickly than any other telescope of comparable resolution.
For the scientists working on the project, that all amounts to an exciting opportunity to learn more about moving objects (including monitoring asteroids near the Earth), transients such as the brief conflagrations of supernovae, dark energy, and the structure of the galaxy.
For computing specialists, it means more data. A lot more data.
The LSST will take between 1000 and 2000 panoramic 3.2 gigapixel images per night, covering its hemisphere of the sky twice weekly. Along with daytime calibration images, this will amount to 20 terabytes of data stored every 2

What will data infrastructures look like 20 years from now?To find out, the European Commission (EC) assembled  a panel of experts to prepare a vision of scientific data e-infrastructures in 2030. The resulting report, overseen by chair John Wood of Imperial College London, was released last week in Brussels.“Data is big news,” said Wood. In the past, date might have been thrown away but it’s now being kept and recorded as emails, videos, mobile phone data and more. CERN produces petabytes of data each year, but with genome sequencing, electronic health records and upcoming experiments such as the Square Kilometer Array, we’re on schedule to generate hundreds of times more. In the words of Wood:

Feature - HPC adds a spark to EDF’s computing capacities

Jean-Yves Berthou is responsible for IT in the research and development area of Electricite de France — a major energy company in Europe. EDF’s 2,000 researchers use computing to work on a number of different projects, including areas such as minimizing CO2 emissions, alternatives to fossil fuels, and ensuring the security of electricity grids. Here, he describes the use and impact of high performance computing (HPC) at the company.
Why do you use HPC?
Berthou: In many cases physical experiments and testing are not possible, for example in the simulation of fuel assemblies and crack propagation in nuclear reactors, or in optimizing electricity production and trading. Even when experimentation is possible, numerical simulation can go beyond what is physically possible. However, experimentation still remains an indispensable tool.

Feature - Inflated performance

Are some performance numbers full of hot air, like this balloon?

The more things change, the more they stay the same. Since the advent of scientific computing, researchers have sought out ways to get more research done in less time and for less money. Proponents of new technologies have, in turn, claimed improvements in technology that may seem too good to be true. How, then, is a researcher to tell the difference?
Back in 1991, Berkeley Lab scientist David Bailey published an entertaining tongue-in-cheek paper in the now-defunct Supercomputing Review entitled, “Twelve Ways to Fool the Masses When Giving Performance Results on Parallel Computers” (PDF). As with any paper discussing computer performance, there are some obvious aspects of the paper that are now out of date, such as the shift from megaflops to teraflops.
“Also, the focus of comparison at the time was vector supercomputers then being manuf

Greek mythology tells of the Lernaean Hydra, a nine-headed serpent with poisonous breath and a unique defensive system: every time you cut off one head, two more grew in its place.
According to legend, the acted as an effective guardian; if it were real, you might want one to guard your most important belongings.
In the world of grid computing, the Hydra data encryption system does just that: it is designed to help protect sensitive data while being stored and transferred.
It may be especially useful in the worlds of medicine and finance, where data is often highly sensitive and security is paramount. (In contrast, while the high energy physics community produces and processes huge volumes of data, the information itself is not financially valuable or personally sensitive.)

Announcement - e-IRG releases new Roadmap on e-Infrastructure

Image courtesy e-IRG

Since the publication of the previous e-IRG Roadmap in 2007, the e-Infrastructure field has undergone several fundamental changes. Networking, grid, data, high performance and commodity computing services are witnessing major organizational and technical changes. The ongoing expansion of the e Infrastructure user communities is also already producing new and updated requirements for the common e Infrastructure.
To help deal with this, the e-Infrastructure Reflection Group — an inter-governmental policy body comprising national delegates from more than 30 European countries — has released the e-IRG Roadmap for e-Infrastructures, (Publications/Roadmap).
Rather than looking at these changes independently, the Roadmap analyzes their impact from the points of view of users, service providers and the society as a whole. Ultimately, the document makes several recommendations aimed at max

Back to Basics – Data management

by TRACEY WILSON
Tracey Wilson is a program manager for Avetec’s HPC Research Division, DICE, the Data Intensive Computing Environment. DICE is a non-profit program that serves HPC and IT data centers in commerce, government and academia by providing independent third-party evaluations of data management practices on its geographically distributed test bed.

From smartphones to weather forecasts, data drives our world.
In the simplest terms, data is information, which can be found in many forms. Back when computer scientists used punch cards to store data, keeping them in order was a way of controlling or managing data.
We used to talk about how incredibly large a gigabyte of data was. Now terabytes and petabytes are the norm in scientific circles, and we will soon be talking about exabytes just as casually. And as the amount of data we generate grows, so does our need for data management.
Data management — the effective control
