Kubuntu Icecream at Akademy
As usual at Akademy we have an icecream cluster here, icecream is the distributed builder for the discerning compiler.
Update: David Faure recommended upgrading to Subversion 1.4 for 10 times extra speed, so I've added that. You can get subversion 1.4 and icecream from:
deb http://kubuntu.org/~jriddell/akademy/ ./
Ooh, lots of nodes, make -j 50 goodness.
