The major axon tracts in the brain are not identifiable using conventional methods or
scans. Scientists at Dartmouth College use diffusion tensor imaging, based on the three-dimensional diffusion
of water, and fiber tractography, which uses special techniques of magnetic resonance
imaging and computer post-processing, to visualize the tracts. Analysis of the raw MRI
data, obtained at the Dartmouth Brain Imaging Center, was performed using Open Science
Grid resources.

Lighting Up Advanced Networks
The UltraLight test bed includes sites in the Americas, Europe and Asia. |
Imagine setting up an ultra-high-
speed Internet connection directly from your home computer to an electronic data warehouse one hundred times the size of the Library of Congress, and then selecting and downloading thousands of books in just seconds. Researchers in the UltraLight project study ways to allow scientists similar access to their data, by changing the way networks are operated, managed, and integrated with grid computing services.
"Current networks are a black box, you put bits of data in with a destination in mind, and hope they come out quickly on the other end," said physicist Shawn McKee from the University of Michigan. "The network makes no guarantees, and there's no way to negotiate with it. We're looking into how to make the network a managed component of grids, like computing and storage resources are now."
Today's scientists produce vast amounts of data, and need to transfer that data among increasingly international collaborations. Transfers currently take place over shared connections, governed by protocols developed in the 1970s that are inefficient for very high-speed, long distance network connections. UltraLight is funded by the National Science Foundation to study ways to replace the older protocols and manage networks as part of grid infrastructures. Tools allowing scientists to connect multiple institutions directly by high-performance network connections, reserve a certain amount of network space for specific transactions, and those that allow grid services to plan large data flows across multiple sites are in development.

From Brazil, with Love: A Look at OurGrid
GRIDtoday editor Derrick Harris recently spoke with Walfredo Cirne, director of the Distributed Systems Lab at the Universidade Federal de Campina Grande in Brazil, about OurGrid—a project he leads (and to which HP has contributed a fair amount of resources) that has become one of the largest computational Grids in Brazil. Cirne will be presenting at the next Gelato Federation meeting, which will take place Oct. 2–5 in Porto Alegre, Brazil.
GRIDtoday: Tell me about OurGrid. Can you give me a brief background on the project and what it hopes to accomplish?
WALFREDO CIRNE: OurGrid is an open, free-to-join Grid. Unlike traditional Grids, joining OurGrid is automatic. No paperwork or approvals of any sort are required. Someone wanting to join OurGrid just downloads the software from www.ourgrid.org and installs it. OurGrid forms a peer-to-peer Grid in which peers donate their idle computational resources in exchange for accessing other peers' idle resources when needed. The vision is that OurGrid provides a massive worldwide compute platform on which research labs can trade their spare compute power for the benefit of all.

Tsai Moves from the South East to the Far East
Heading east: Min Tsai |
Min Tsai is an excellent example
of how Grid computing helps
international collaboration. In
September he will move back to
Taipei, leaving CERN where he
has been acting as liaison for
the South-Eastern European
Grid-enabled e-Infrastructure
Development (SEE-GRID)
project. He will take up the role
of deputy manager of the first
Asian Regional Operations
Centre (ROC) for the Enabling
Grids for E-science (EGEE)
project at Academia Sinica in
Taipei.
Tsai’s path to Grid computing
is unusual. Neither a computer
scientist nor a physicist, he
studied mechanical engineering
in the US then worked in
industry in telecommunications
and networking. Hired because
of his networking background,
he arrived at Academia Sinica
just over a year and a half ago
to help set up Grid computing
there. His first assignment was
to go to CERN and learn handson
about Grid operations by
working in the Grid Deployment
group, and after six months he
was offered the liaison position
for SEE-GRID.

Challenging the World's Largest Computing Grid
PPARC Press Release, September 21, 2005
Enough data to fill 17,000 CDs(*) were transferred from Edinburgh University to the CCLRC Rutherford Appleton Laboratory (RAL) in nine days, as part of the latest networking challenge by particle physicists. Delegates to the UK e-Science All Hands Meeting in Nottingham will be able to watch the progress of the challenge in real time on a screen showing data being exchanged between sites worldwide.

NSF Awards $2 Million for CLEANER Project Office
NCSA News Release, September 13, 2005
CHAMPAIGN, IL — The National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UIUC) has received a grant of $2 million to lead a two-year intensive effort to develop a roadmap for CLEANER, the Collaborative Large-scale Engineering Analysis Network for Environmental Research.
