Petascale Workshop Summary

PetaApps Solicitation

Junping Wang at the NSF has asked for our feedback about both the PetaApps and the CMG programs in order to inform NSF's thinking about possible follow-ons to these two programs.
The PetaApps solicitation is linked below to allow TOY attendees to review and comment on it.


Also, please refer to Dr. Junping Wang's discussion notes available here

You are kindly invited to participate in the Theme-of-the-Year 2008 Geophysical Turbulent Phenomena Workshop 2 entitled "Petascale Computing: Its Impact on Geophysical Modeling and Simulation."

The goal of the workshop is to establish a roadmap for most-productive use of petascale computing systems for improving our knowledge of important geophysical dynamical processes. Petascale systems will be available on a five-to-ten year time horizon. The purpose of this meeting is to help the geophysical dynamics community position itself to make the best use of these resources when they become available.
Given the large range of length and time scales accessible with such systems, we anticipate significant changes may be required to models, algorithms and analysis methods so that new discoveries will be possible.
The workshop is organized by five themes, which explore applications ranging from global-scale, regional-scale, and small-scale dynamical phenomena, and includes coupled dynamics that involve multi-scale processes. There is also emphasis on the realities of using and analyzing results from such large-scale computing systems and on the software and model adaptations required to optimize their use.
Because applications vary widely from small-scale process parameterization to global-scale forecasting, we encourage meeting participants to consider one simple unifying question as they anticipate workshop participation. Simply put, that question is:

"If you had access to a petascale computing system, what would you do with it?"

We anticipate enlightened answers to this question from international experts giving invited talks, from contributed talks and poster presentations, and from round-table and open discussions.

The workshop will be held at the National Center for Atmospheric Research's Mesa Laboratory, Main Seminar Room, 5-7 May 2008.

The Institute for Mathematics Applied to Geosciences (IMAGe) is a group within the National Center for Atmospheric Research (NCAR) for the purpose of advancing mathematical theory and its application to all facets of NCAR and the geophysical community at large. IMAGe is substantially funded by the National Science Foundation. IMAGe is composed of four groups; the Data Assimilation Research Section, the Geophysical Statistics Project, the Turbulence Numerics Team, and the Computational Mathematics Group. For more information about IMAGe, including post-doc positions, please contact Doug Nychka.


NCAR was formed in 1960 and has a broad interdisciplinary research program involving more that 1000 employees of which several hundred hold advanced scientific or engineering degrees. The NCAR scientific program includes nearly all aspects of the atmosphere including climate and weather, atmospheric chemistry, ecology, instrumentation, scientific computing, and economic and societal impacts of atmospheric processes.
