Carpet Developer Workshop Announcement

Dear Colleagues,

We would like to invite you to attend a Carpet developer workshop to be hosted by the Center for Computational Relativity and Gravitation at the Rochester Institute of Technology on August 23th, 24th, 25th and 26th (2010). This workshop is aimed at experienced Carpet users that want to gain further expertise on the internal workings of the Carpet driver, and, thereby, to be able to contribute to the infrastructure development. This workshop will be led by Erik Schnetter, the main architect for the Carpet AMR infrastructure, and will count with the presence of an HPC specialist. One important goal of this workshop will be to discuss and implement ways to improve the performance for Cactus-based applications for current and future high-end petascale architectures. Due to space limitations, we encourage you to contact the organizers as soon as possible to register your presence.

Sincerely, the organizers:

• Manuela Campanelli (manuela@astro.rit.edu)
• Bruno C. Mundim (bcmsma@astro.rit.edu)
• Erik Schnetter (schnetter@cct.lsu.edu)

Program

The first two days of the workshop will be dedicated to the theory of adaptive mesh refinement (AMR) and related algorithms. The last two days is reserved for hands-on work on the development of the Carpet infrastructure. Details of the program are still to be announced.
