These software tools aim to simplify the solution of common and important computational problems and have substantially benefited a wide range of scientific and industrial applications. These benefits are accounted not only for running efficiently in high performing computing environments but also realizing computation that would not have been possible otherwise. Despite these successes, there is still a need for a greater infrastructure to reach out academia and industry through a dissemination and instruction on the state-of-the-art tools for high performance computing environments and simultaneously provide an umbrella for tool developers to receive the feedback from these communities. This workshop is part of an approach to build such an infrastructure. The four-day workshop will present an introduction to the ACTS Collection for application scientists whose research demand includes either large amounts of computation, a large volume of data manipulation, the use of robust numerical algorithms, or combinations of these. The workshop will include a range of tutorials on the tools (currently available in the collection and some deliverables from the DOE SciDAC ISICs), discussion sessions aimed to solve specific computational needs by the participants, and hands-on practices using the NERSC's state-of-the-art computers. We are planning to organize parallel sessions and group the tutorials by topics, as follows: Direct and Iterative Methods for the solution of linear and non-linear systems of equations PDE's and Multi-level Methods Numerical Optimization Structured and Unstructured meshes (Generation, Manipulation and Computation) Development of High Performance Computing applications Performance monitoring and tuning Grid computing DOE will fully sponsor a limited number of graduate students and postdoctoral fellows to participate in this event. This support includes round-trip transportation to and from Berkeley, local transportation, lodging, meals and workshop materials. Proposals from other research scientists are also encouraged. The deadline for applications is June 9, 2003 and they should be submitted using the application on-line form: http://acts.nersc.gov/events/Workshop2003/application.html. Students and postdoctoral fellows should submit an abstract describing the nature of their work, future plans and/or current needs for computation. A letter of recommendation from the applicant's supervisor also needs to be provided using the recommendation on-line form: http://acts.nersc.gov/events/Workshop2003/recommendation.html The recommendation letter must also arrive no later than June 9, 2003. Other applicants must submit a letter outlining their current work and future plans and needs for computational resources with a list of publications . For more information on the workshop, please contact Tony Drummond at (510) 486-7624 or Osni Marques at (510) 486-5290.
