On November 9, Oklahoma State University hosted the Cimmaron High Performance Computer Center grand opening celebration. Cimmaron is part of the OAK project.
Here are some pictures from the event.
The data center is rated at 1 MW, approximately the power that goes into 100 houses.
Cimmaron uses closed-loop cooling. It has a 2500 gallon storage tank of pure water with no propylene glycol. That water is used to cool the air in the data center.
