[olug] Fwd: FIrefly Retirement this summer

[Shawn Mattingly]

Taking classes at UNO and using the system while you were there would be a
lot less expensive than powering and cooling them yourself.  I took a tour
of the Firefly cluster once when they were commissioning it.  I thought it
was really neat that they cooled it without a raised floor.
