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
Detailed workshop information can be found at https://docs.einsteintoolkit.org/et-docs/ET_Workshop_Spring_2012.

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. |

Setup
- Wireless access is through the GTVisitor network. One account per person, please. It will work on multiple devices simultaneously.
- The virtual machine for the workshop is [3] and will run in virtualbox
Hands on material
WaveToy
The source code for the example thorn and the slides is available at via
cd $HOME ./GetComponents -a https://svn.einsteintoolkit.org/documents/Workshop_Spring_2012/example_wavetoy/Cactus/misc/WaveToy.th cd Cactus echo 'Introduction/WaveToy' >>configs/sim/ThornList simfactory/bin/sim build
Once built, you can run this in one line via simfactory
simfactory/bin/sim create-run wavetoy --parfile wavetoy-misc/WaveToy.par
Static TOV
Edit par/static_tov.par as Frank indicated and save as $HOME/Cactus/fast_tov.par
To run enter:
cd $HOME/Cactus exe/cactus_sim fast_tov.par
Visualization, Hands-on I
Download the slides and some extra sample data via
cd $HOME svn co https://svn.einsteintoolkit.org/documents/Workshop_Spring_2012/handson_sviz .
Make sure you have 3d data! If not, add these lines to your tov parameter file and rerun for a bit:
CarpetIOHDF5::out3d_every = 1 CarpetIOHDF5::out3d_vars = " HydroBase::rho "
These give data under the file name rho.xyz.h5. Alternatively, add the following parameters
CarpetIOHDF5::out_every = 1 CarpetIOHDF5::out_vars = "HydroBase::rho"
which give data under the file rho.h5. Either way works fine. We will assume the latter for the moment.
Follow the directions on the first slides to create a plot of how the evolving TOV differs from its initial state.
Other suggestions for visualization tasks are contained in the slides.
Analysis: Thorn Writing
Roland's partial and full thorn solutions are available via
./GetComponents -a https://svn.einsteintoolkit.org/documents/Workshop_Spring_2012/handson_analysis/Cactus/misc/CoreTracker.th
