I’ve been checking this web site regularly for a long time, so I’m happy to report that the Green500 list is out! Congratulations guys.
From their site
The inaugural Green500 List was announced on November 15, 2007 at SC|07. As a complement to the TOP500, the unveiling of the Green500 ushers in a new era where supercomputers can be compared by performance-per-watt.
The ERDC MSRC (my site) is number 145 with its Cray XT3; the top slots are dominated by the Blue Gene. Take a look at the whole list.
