The concept is very real world, but quite old. Back in the 80s I worked for a Danish bank - our IBM 3090s were water-cooled as were the cooling-towers. Around '89 we installed heat-exchangers for re-using the hot cooling water for warming up the offices (in winter). /Per Jessen, Zürich _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
