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)

Workshop Location

The workshop is going to take place on room 1100 of the The Center for Student Innovation at RIT. Room 78-2015 of the CIMS (Center for Integrated Manufacturing Studies) building (building 78, Louise M. Slaughter Building) on RIT campus will also be available for the participants.

Driving directions

A quick note: The Radisson, RIT Inn, Fairfield Inn Airport, Holiday Inn Marketplace, and Best Western all have a free shuttle van to campus. Ask to be dropped off at the Innovation Center if possible.

From the Radisson, the RIT Inn, or any of the other local hotels located along Jefferson Rd./West Henrietta Rd., you will want to head West on Jeferson Rd. (Rte. 252), past the first entrance to RIT (Lowenthal Drive), and make a left at the second entrance to RIT (Lomb Drive). At the roundabout, go straight, and head toward the visitor's booth. You will need a visitor's parking pass to park on campus. Have the guard direct you to J-Lot or T-Lot. Both have visitor parking available; for J-Lot, it is at the top level, and for T-Lot it is the nearest row of parking. The entrance to the building is at the top of the roadway between these two lots, currently under construction.

From hotels near the airport grounds: Take Scottsville Rd (Rte. 383) South to Jefferson Rd. (Rte. 252), and make a left. Go straight through the first light (River Rd.), and make a right at the main RIT entrance (Lomb Drive). Follow the instructions above to the visitor shack and parking lots.

Walking directions

It is a 15-20 minute walk from the Radisson to the workshop location. Head onto campus along Lowenthal drive, and make your way to the "quarter mile walk" that runs through the main stretch of campus. Turn right, and go as far as humanly possible to the west. The final building you will reach will be building 78, the CIMS building.

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.
