Craig Venter, delivering the opening address yesterday at the BioITWorld conference here, said that computer power will be the limiting factor in crunching, storing, and manipulating the data necessary for linking the promise of genomics to insights into gene function, protein interaction, and personalized medicine. To underscore his point, he said the Celera computers that sequenced the human genome – the 1.5 teraflop, 120 terabyte machines that took up 6,000 square feet of space – are relics.
