It's awesome we live in a world where we can throw 100-200 million cpu hours at something of a whim.

That each of those cores are billions of times faster than my first PC just puts the icing on the cake.

Thanks for sharing! I'm now curious to know what the energy bill came to and whether it would make it to the list of most expensive domain names[1].

100M...200M core h, 10 W/core, 50 $/MWh and we get 50k...100k $.

FWIW, we ran it on and off for about a month IIRC, as the cluster was put through its paces prior to going live. I also seem to remember Matt Jones doing a minor tweak to the scallion code to speed things up as well...
