2023 SST User Group Meeting

SST User Group Meeting

September 25-26th, to be held at the Klaus Advanced Computing Building, Room 1116 E/W

The Structural Simulation Toolkit (SST) user group meeting will be held on the Georgia Tech campus on September 25th and 26th. This user event is hosted by the Center for Research into Novel Computing Hierarchies (CRNCH) and will include presentations by SST users as well as discussions of future efforts to grow the SST codebase and user community.

Event Location

We will be meeting in the Klaus Advanced Computing Building in the main room off the atrium, Klaus 1116 E/W. Please see below for more detailed directions.

Event Sponsors

Webinar Link

We anticipate this will primarily be an in-person event. However, if you are unable to travel but are interested in the activities of the SST User Group, we have created a best-effort Zoom webinar option.

Please note that you should have received a login from your registration or a passcode to connect in the welcome email. If you did not receive either of these emails please contact the event organizers below.


Thanks to generous sponsorship, this user group meeting will be free to attend. However, you must be registered to attend this event, so we can plan for catering for breakfast and lunch each day. Registration is now closed.

Call for Lightning Talks

Lightning talk proposals are closed.

Dining Suggestions

Please see our separate page of local dining options for lunch (for those who need it) and for dinner here.

Travel and Transporation

The event venue is located in Midtown Atlanta, which is easily accessible from Hartsfield-Jackson airport via rideshare, taxi, or the MARTA rail system. We will be meeting in the main Klaus conference room off the atrium, Klaus 1116 E/W. Please see below for a picture of the entrance to the Klaus atrium.

To take MARTA and the Tech Trolley to Klaus Advanced Computing Building

(Additional map to Klaus https://www.scs.gatech.edu/content/building-facilities)

  1. Take the RED or GOLD train to the 10th street MARTA station. Either line will stop at the North Avenue or 10th street stations. Tickets are $2.50 each way, and it is not worth using the MARTA app at this point in time. 
  2. At the south exit of the train station, the Tech Trolley (a bus) will stop and pick up riders every 10-15 minutes. You can check where buses are using the Georgia Tech bus tracking website at bus.gatech.edu. It is also about a 15 minute walk from the station to Klaus.
  3. If you are taking the trolley, ride it 4 stops from the 10th street station to the Klaus Advanced Computing Building. It will be a large building, and the bus stop is right at the baseball field. 
  4. You will go up the rainbow staircase. The atrium and Klaus user group meeting space will be on your right. We will be meeting in the main Klaus conference room off the atrium, Klaus 1116 E/W.

To take an Uber/Lyft to Klaus Advanced Computing Building; Meeting is in Klaus 1116 right off the atrium

It takes about 40-50 minutes to get from the airport to the Klaus building via the train and the Tech Trolley. However, if you are in a hurry, you can take a Lyft/Uber which takes about 25-30 minutes once you are picked up. 

Key note: The rideshare pickups keep moving at the Atlanta airport so please check signs. As of September 2023, they are currently on the ground floor (down one floor from baggage claim) and in the North Hourly parking lot.

Hotel Information

The User Group meeting does not have a reserved hotel block for attendees. Most of the hotels in Midtown Atlanta (North Avenue – 14th Street) are reasonable as far as price, ratings, and distance to campus. You may want to either select the GT Hotel or a hotel near the 10th Street MARTA station so that you can take the Tech Trolley to the Klaus building on campus.
