Image of the Week - Mapping Science

This image, entitled Internet Splat Map, was produced in 2009 by William Cheswick and Ben Worthen. It was produced by sending a large number of IP packets out randomly across the network. Each packet is designed to self-destruct after a set amount of time; when it does, the packet failure notice it returns describes the path it took. The visualization of the resulting data was created using place and route software from the semiconductor industry.
These maps can be used to find security gaps or monitor the networks during wartime bombing raids.
BBN (early ARPANET) is the random scatter of green in the middle. Sprint is the organized star topology in purple near the top. AOL is a gray disconnected island in the lower center. There is little correlation between this network connectivity graph and physical geography, except for a clustering of Pacific Rim connectivity. To see a similar map with labels, download the map PDF here.

Announcement - LiveChat a smashing success, new column launched

Submit a question to our new “Ask an Expert” column, and you too could look as enlightened as this man. Image courtesy brainloc

Over the course of last week’s one-hour live chat, over 60 of you tuned in to learn about what makes a resource and project a match made in heaven. You had a lot to say, too, submitting a total of 75 comments, questions, and insights. Some of you even made new friends, exchanging contact information.
You can still read the chat log on our website – and indeed, about twenty already have. But we also followed up with a question and answer session over at Nature Network.
What next? We’d love to do another live chat at some point, and as always, we welcome suggestions on topics and experts. But today, we have an exciting announcement to make. We are launching a new column which will appear periodically within iSGTW: “Ask an Expert”

Announcement - XtreemOS Second Summit 2010

XtreemOS Second Summit 2010 will take place in conjunction with EuroPar 2010 30 August 2010 in Ischia-Naples, Italy.
Large-scale distributed systems like grids and clouds provide means for executing complex scientific and business applications. But they often involve installing and interacting with several layers of middleware, a difficult task for inexperienced users. Tools developed for grid use are demanding and complex, especially because they are based on operating systems that are not designed to manage distributed and versatile resources.
XtreemOS can be seen as an alternative to traditional grid middleware, facilitating the use of federated resources for scientific and business communities. XtreemOS provides for users, the vision of a large powerful single workstation environment, but removing the complex resource management issues of a grid environment. When installed on a participating machine, XtreemOS provides for the grid what an opera

Next week: Chat live with experts about computational resources

What makes a grid perfect for one project, but a cloud better for another? When is a high-performance computer wasteful overkill, or a small cluster underpowered?
To answer these questions, iSGTW has invited experts from around the world to join us on Wednesday, 14 July 2010 at 10:30 a.m. CDT/4:30 p.m. CEST for a one-hour live chat - and you’re invited.
Can’t make it to the chat? No problem. For a week following the chat, an even larger host of experts will join us in our online forums to answer questions. To volunteer to serve as an expert, please email us at [email protected].
We’ll be announcing the identity of our experts throughout the week by adding them to this page. But in the meantime, we’d like to offer you a preview of some of the experts you can expect to hear from next week.

Last week, distributed computing experts from around the world converged on Chicago to attend OGF29 and the ACM International Symposium on High Performance Distributed Computing 2010 (HPDC).
“It’s been a quite successful HPDC,” said Peter Dinda, the event’s program chair. “In terms of the grid context, it’s good to have it co-located with Open Grid Forum.”
Both events benefited from the co-location, reporting increases in attendance.
Although the conference chairs did not actively seek out programming on the topic of clouds, this emerging technology became a major theme throughout both conferences.
OGF29’s second day featured a status update on the Open Cloud Computing Interface, and cloud technology demonstrations by t
