Kluster @ aKademy
At aKademy we got really cool hardware from transtec to accelerate the development by shortening compiling times with icecream.
We did some quality tests for Debian and rebuild all Sarge packages with 2 blades (Intel Xeon based systems) from transtec and sponsored HP notebooks which were on daily use in the tutorials and worked 2 days compiling Sarge.
KDE developer Diego Iastrubni comments: "It kicks ass, I have running 20 or maybe even 30 processes of 'make', someone even compiled OpenOffice.org because he was bored."
