You apparently get 1 teraflop for $2.10/hour. That’s almost affordable by a grad student for a thesis project. And its only $18.5K/year for continuous operations. Sound like a lot of money? No initial purchase price. No electricty needed. No floor space to rent. No charges for network connectivity. No cooling costs. No system administrator salaries. No service contracts. Nothing to recycle when you’re done.
