SPRING 2008 Wednesday April 16th, 2008 Topic: Maelstroem II - Continuing Arthur C. Clarke's Legacy Abstract: Arthur C. Clarke's Maelstrom II is a science-based mini drama, produced and directed by ILM digital artist, Jeroen Lapre'. It is based on the short story, by Sir Arthur. Jeroen will talk about how he is adapting the short story into a digital short. The goal of this project is to combine a human story with real science, to make science compelling. Jeroen consulted with volunteer scientists and engineers, from NASA and the space community, to help ensure this piece is as scientifically accurate as possible. He will also talk about how the project has evolved into a web-based distributed "virtual production" over the years. Speaker: Jeroen Lapré, ILM digital artist/technical director Wednesday April 30th, 2008 Topic: Troubleshooting Petascale Distributed Science Abstract: Petascale science involves not only the creation of massive datasets at supercomputers or experimental facilities, but also the subsequent analysis of that data by a user community that may be distributed across many laboratories and universities. This talk will describe at a high level the challenges of: developing tools for the detection and diagnosis of failures in end-to-end data placement and distributed application hosting configurations; constructing an end-to-end monitoring architecture that uses instrumented services to provide detailed data for both background collection and run-time event-driven collection; and constructing new monitoring analysis tools able to detect failures and performance anomalies and predict system behaviors using archived data and event logs. Speaker: Dan Gunter, Lawrence Berkeley National Labs Wednesday May 7th, 2008 Topic: Labs of the World, Unite!!! Abstract: eScience is rapidly changing the way we do research. As a result, many research labs now need non-trivial computational power. Grid and voluntary computing are well-established solutions for this need. However, not all labs can effectively benefit from these technologies. In particular, small and medium research labs (which are the majority of the labs in the world) have a hard time using these technologies as they demand high visibility projects and/or high-qualified computer personnel. OurGrid was designed to fill this gap. It is an open, free-to-join, cooperative grid in which labs donate their idle computational resources in exchange for accessing other labs' idle resources when needed. It relies on an incentive mechanism that makes it in the best interest of participants to collaborate with the system, employs a novel application scheduling technique that demands very little information, and uses virtual machines to isolate applications and thus provide security. The vision is that OurGrid enables labs to combine their resources in a massive worldwide computing platform. OurGrid is in production since December 2004. Any lab can join it by downloading its software from www.ourgrid.org. Speaker: Walfredo Cirne, Google
