Spring Einstein Toolkit Workshop 2012
We prepared a flyer, which can be printed or otherwise distributed.
Announcement
The Einstein Toolkit (http://einsteintoolkit.org) will host its spring workshop 2012 following the April APS meeting in Atlanta, GA, from Tuesday, April 3rd 4pm to Friday April 6th noon.
This workshop is targeted at new and potential new users of the relativity infrastructure. It will provide a general introductions into numerical relativity (although some previous knowledge would be beneficial) and in code development within large collaborations. Hands-on sessions will help to familiarize attendees with the Einstein Toolkit. Participants are asked to bring their own laptops. We would like to invite especially students from physics and computer science to participate.
The number of attendees is limited, and while registration is free, it is required. We anticipate to be able to support a small number of participants financially, by covering parts/all of their travel, hotel and meal cost. Preference will be given to students.
In order to register, write an email to workshop@einsteintoolkit.org, specify:
- your name, affiliation and title
- your estimated arrival and departure time/date
- whether you apply for support (and if so, state if you are undergraduate / graduate student / postdoc)
- your special needs

Spacetime Coordinates and Contact Information
| Dates | Tues, 3. April @ 4pm -- Fri, 6. April @ noon |
|---|---|
| Location | Room 319, Georgia Tech Student Center, Georgia Tech, Atlanta |
| Contacts | Workshop email list: workshop@einsteintoolkit.org, emergencies: Frank Löffler (knarf@cct.lsu.edu, +1-225-202-1752) or Tanja Bode (tanja.bode@physics.gatech.edu, +1-814-360-2715) |
| Hotel | A small block of rooms was reserved at the Hampton Inn Atlanta - Georgia Tech, 244 North Ave NW (404-881-0881). The group rate was $117 per night plus tax (appr. 16%, resulting in a ~$136 rate) and included a hot breakfast and high speed wireless access. A group web page was available to book online, or you could reserve by phone at 404-881-0881 and ask for the "Einstein Toolkit Workshop" rate. Attendees had until 20. March to reserve.
In addition, a small block of rooms were reserved at the Hotel Midtown Atlanta. The group rate was $89 per night for single occupancy, including breakfast and high-speed internet. For an additional person, add $10 (to cover breakfast costs). Though less convenient to either the APS meeting or this workshop, both can be conveniently reached by transit from the Midtown MARTA station a block away. Reservations at this rate could be done by phone only at 404-873-4800. The block of rooms was released on 26. March. |
| Transportation - Hotel | The best way to get to the hotels from the airport (or elsewhere) is by taking MARTA's red or gold rail line, which costs $2.50 one-way. The Hotel Midtown Atlanta is a block away from Midtown station. For the Hampton Inn, get off at the North Avenue station. It should take approximately 20 minutes to either station. From North Ave station, walk west for ~0.5 miles or transfer to MARTA bus route 26 to the stop immediately in front of the Hampton Inn. |
| Transportation - Workshop | The student center is a 5-minute (~1/3 mile) walk [1] from Hampton Inn. From the Hotel Midtown Atlanta, Georgia Tech campus (specifically the student center) can be easily reached by taking the Georgia Tech Trolley (free) from the Midtown MARTA station to its end station. |
| Transportation - From the APS (Hyatt) | The Workshop is a 1.5 mile walk from the Hyatt where the APS is taking place. The most convenient way to reach the Workshop location on Tuesday is to take MARTA Bus Route 1 from Spring St [2] (a block away from the Hyatt) directly to the workshop hotel. |
