CHALLENGES IN ASTROPHYSICAL COMPUTING ===================================== National Radio Astronomy Observatory Array Operations Center (http://www.aoc.nrao.edu/directions) Thursday, 11 November 2004 AOC Auditorium The goal of this "mini-symposium" is to bring together NRAO people and Los Alamos National Lab staff interested in the general areas of high-performance computing, numerical astrophysical simulation, advanced imaging, difficult problems in radio interferometry, visualization and data mining, and other areas that are challenging computationally and will be driving future research and development in our respective areas of interest. This will be fairly informal, and is intended to spur discussion between groups (that have not traditionally had much contact) on areas of possible collaboration in addition to the pedagogical aspects of the talks. There is time set aside for discussion and short presentations. Schedule: --------- 0900 Start (and brief welcome etc.) 0900 - 0930 Talk 1 - Steve Myers (NRAO) 0930 - 1000 Talk 2 - Salman Habib (LANL) 1000 - 1030 Break 1030 - 1100 Talk 3 - Kev Abazajian (LANL) 1100 - 1130 Talk 4 - Sanjay Bhatnagar (NRAO) 1130 - 1200 General Discussion and/or short presentations 1200 - 1330 Lunch 1330 - 1400 Talk 5 - TBD (LANL) 1400 - 1430 Talk 6 - Tim Cornwell (NRAO) 1430 - 1500 General Discussion and/or short presentations 1500 End of "formal" meeting 1500 - hang around and chat or go home! Scheduled Talks: ---------------- Talks are 30m duration (20m talk + 10m discussion) The intention is that these talks highlight "tough problems" in selected areas of astrophysics and computation, and should be aimed at the broader audience. The talks and discussion will likely be fairly technical, but hopefully accessible to both the more science-oriented participants and those with CS background. Of particular interest will be issues that cross-cut the various areas, such as possible application of techniques used in n-body simulation to advanced imaging problems - hopefully the discussion will bring out these opportunities! Steve Myers - "Challenges in Cosmic Microwave Background Data Analysis" Salman Habib - "Challenges in Simulation of Large Scale Structure and Cosmology" Kev Abazajian - "Challenges in Weak Lensing" Sanjay Bhatnagar - "Challenges in Advanced Imaging and Deconvolution" (speaker TBD) - "Challenges in High-Performance Visualization" Tim Cornwell - "Challenges in low-frequency interferometry: large-N small-D concepts for the Square Kilometer Array" Discussion Sessions: -------------------- During these scheduled half-hour periods, there should be time to discuss various topics which may or may not have come up during the presentations. Also there is time for very short (~3-5min) presentations by attendees (particularly students) on relevant problems and projects. These are encouraged to be aimed at spurring discussion or pointing out problems that are on the frontier of computational astronomy and astrophysics. Short presentations on reserch possibilities not covered in the main talks are particularly welcome! Venue: ------ The mini-symposium will be held in the AOC Auditorium. As this is an NRAO holiday, the building will be locked, but we will make access available for the meeting. As this is an informal meeting scheduled on short notice, there will not be a wide selection of "catered" break snacks, though there will be some cookies and coffee available from the usual NRAO coffee-like-substance dispensing units. Lunch is not provided, we will likely head off in small groups to various restaraunts, etc. (there is also a canteen on the Tech campus). New Mexico Symposium and Janksy Lecture ======================================= Wednesday, 10 November 2004 See http://www.aoc.nrao.edu/events/nmsymposium/2004 Note - there is a dinner for registered participants of the NM Symposium!
