#SC09 Highlights - Thursday Nov. 19th and Friday Nov. 20th

Another SC has come and gone, and overall I really enjoyed it again this year. It is one of my favorite conferences to attend each year.

In this posting I will provide some highlights for Thursday Nov. 19th and Friday Nov. 20th.
Highlights from previous days of the conference can be found at the below links:

Thursday Nov. 19th, started out with the keynote by Al Gore on climate change. He is a very good speaker. At times he was quite humorous, and at other times he was quite serious. Some quotes from his talk are below:

• As much urban habitat will be developed in the next 35 years than has ever been developed.
• In the last 100 years the earth's population has quadrupled from 1.6 billion to 6.8 billion.
• By beginning of next year there will be 1 billion transistors for each of the 6.8 billion people on earth.
• Climate crisis is not a political issue. It is a moral issue.

After the keynote I attended an exhibitor forum on Virtualization and Cloud Computing and then walked around the exhibit floor some more. At 12:15 I attended the "HPC Saving the Planet, One Ton of CO2 at a Time" BoF. One thing we were told that was worth taking a look at was the Smart 2020 report. After the BoF I went back and finished my tour of the exhibit floor. At 2:15 p.m. I attended the Masterworks session titled "High Performance at Massive Scale: Lessons Learned at Facebook" by Robert Johnson. It was a full session, and I even had to wait for some room to free up after the previous session, before being allowed to go in. Security was quite strict on fire regulations this year. No standing allowed in session rooms, and no sitting against the walls out in the lobby. Robert talked about how Facebook was managing data. A few interesting and impressive statistics about Facebook that he mentioned are as follows:

• > 300 million users
• 200 billion monthly page views
• 1 billion chat messages per day

After the Facebook Masterworks session I attended a technical paper presentation: "VGrADS: Enabling e-Science Workflows on Grids and Clouds with Fault Tolerance". I then took a break before heading downtown to the Technical Program Reception at the Portland Center for Performing Arts where there was plenty of food and entertainment.

On Friday November 20th, I attended the Grid Computing Environments (GCE) Workshop.
In the afternoon of the workshop I presented a paper co-authored by Roger Curry, myself and Rob Simmonds entitled "Social Networking and Scientific Gateways". The paper describes different approaches for integrating social networking in scientific gateways, and highlights our experiences using Facebook, Ning and Elgg in developing the GeoChronos scientific gateway. Slides for that presentation are available here. Being the afternoon of the last day I had anticipated not many being in attendance. However, there were still about 40 people in the room which I thought was pretty good. Wireless was still running, even though we were told it was going to be cut off at 12:00, so I was able to give a brief live demonstration of GeoChronos at the end of the presentation.

Overall, the day was full of many excellent papers. I was quite interested by several of the papers that were making use of iGoogle and OpenSocial gadgets. There was also an interesting paper on a TeraGrid user portal designed for mobile phones. A list of the papers I found most interesting is below. Slides for these and other papers from the workshop can be found here.

• Lan Zhao, Shuang Wu, Rakesh Veeramacheneni, Carol Song and Larry Biehl. "Delivering Real-time Satellite Data to a Broader Audience"
• Rion Dooley, Stephen Mock, Praveen Nuthulapati, Patrick Hurley and Maytal Dahan. "Evolving Interfaces to Impacting Technology: The Mobile TeraGrid User Portal"
• Wenjun Wu, Thomas Uram and Michael E. Papka. "Web 2.0 Based Social Informatics Data Grid"
• Zhenhua Guo, Raminderjeet Singh and Marlon Pierce. "Building the PolarGrid Portal Using Web 2.0 and OpenSocial"
