What is this distro, I was just googling and there was this mysterious screenshot.
An Ubuntu-base distro for Beowulf clusters developed by the University of the Basque Country in Spain: http://www.ehu.eus/AC/ABC.htm
ABC GNU / Linux distribution is based on Ubuntu and specializes in the automatic construction of high-performance Beowulf clusters with only boot in "live " mode in frontend or being installed on your hard drive. Diskless nodes tear through PXE. Use as Gnome window manager . Integra Resource Monitor Ganglia . This is the first distribution that integrates all these features. It was published a scientific article on this system and presented at the IEEE Symposium ICAT2009 held in Sarajevo (Bosnia & Herzegovina).
