What happens to all the brain scans when a neuroscience study is over? Are the images stored? Can another researcher run the same algorithm from the study, but on a different set of brain images? And if a researcher in India accessed brain scans taken in the UK, for example, would there be enough supporting clinical and image data to make it useful? In February, a high-level workshop was held in Geneva, Switzerland, to address these issues.

Your iSGTW correspondants interviewed several participants on video, and you can view these in the article.

StratusLab has released the first open-source cloud solution designed for the grid.
The StratusLab project has released the first version of its cloud computing software, which aims to provide a full cloud solution for grid and cluster computing.
The release is a technology preview (beta test) and not production-ready yet, but it will give system administrators and users a chance to try out the new features of what will become an integrated solution for cloud management and running grid services within clouds.
The software is based on the OpenNebula open-source toolkit for cloud computing management and can be used as an interface for managing cloud sites. It also provides a range of tools and services specifically designed to facilitate integration of cloud and grid technologies. These include automatic configuration of sites and integration with fabric management tools such as the

Once a user has signed up for a Cinefilia account they can review whether they like or dislike one of hundreds of films on the database. The system then ‘learns’ that user’s preferences and generates personalized recommendations accordingly. (But in order for the results to be accurate a minimum of 20 films must be rated by a user.)   Ciuffo aims to increase the amount of Brazilian films on the database because 95% of users on his site are Brazilian, possibly because there are currently no recommendation systems for Brazilian films. Ciuffo is looking for partners to help him improve the recommendation software algo

Project Profile - From grids to clouds and beyond: GRNET supports Greek researchers

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

Feature - Ultra-fast networks: The Final Frontier A network researcher in awe of the billions of dark matter particles simulated on 15 ultra-high definition monitors. 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

Announcement - New European Petaflop supercomputer available in 2011

Photo courtesy PRACE

In 2011, the 1.6 Petaflop French supercomputer, Curie, will be installed and available for use. Powered by more than 90,000 processor cores, it will be exclusively dedicated to European research and available for all fields of science, including high-energy and plasma physics, climatology and much more.
“It is crucial to have high computing power to simulate, with the most possible realism, the past of our climate, the current conditions and its future evolution according to various scenarios,” said Jean Jouzel, vice-president of the IPCC (Intergovernmental Panel on Climate Change).
Scientists and engineers will also be able to use Curie’s simulations to explore the properties of various materials, improve aircraft and car construction, design better drugs, understand the intricate molecular functions of the human body and conduct simulations that are impractical in reality.

Animation from the NICAM model simulation of 21 May - 31 August 2009, showing cloudiness (based on outgoing long-wave radiation) in shades of gray and precipitation rate in rainbow colors, based on hourly data from the simulation. The cloudiness is shaded in brighter gray for thicker clouds, and the colors range from shades of green, indicating precipitation rate less than 1 mm/day, to yellow and orange (1 - 16 mm/day), to red (16-64 mm/day) and magenta (> 64 mm/day). The animation begins zoomed in over India and the Bay of Bengal, showing the fact that tropical cyclone Aila, which in reality made landfall near Calcutta killing dozens of Indian and Bangladeshi citizens and displacing over 100,000 people from their homes, was very accurately predicted in the simulation.

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

Agile architecture is essential if a large-scale infrastructure like the Ocean Observatories Initiative is to last three decades, as mandated.
“The Ocean Observatory has been in planning for fifteen years and more,” said Matthew Arrott, OOI’s project manager for cyberinfrastructure. “It is our anticipation, over a 30 year lifespan, that we need to account for user needs and the technology that we are using all changing.”
That’s why they’ve focused their attention on creating an infrastructure that can interface with a wide variety of software packages and computational resource providers.
“The observatory supports a broad range of analysis with the expectation that the majority of the analysis capability will be provided a

As wireless devices become increasingly common, and common devices become increasingly “smart,” wireless grids become increasingly practical. That means that the timing is perfect for WiGiT, a wireless grid testbed which will begin testing its alpha software in June.
The purpose of WiGiT (Wireless Grids innovation Testbed), according to the Syracuse University project leader Lee McKnight, is to refine open specifications for a wireless grid standard, and create a stable platform for experimentation.
“With WiGiT we expect to be able to do these large scale experiments from campus to campus, and we can run little experiments on that,” McKnight said. “Open specifications will make it easier for others to latch on.”
