From the early 1990s to the early 2000s, the performance of our n-body code for galaxy formation has improved by 2000-fold, but the performance per watt has only improved 300-fold and the performance per square foot only 65-fold. Clearly, we are building less and less efficient supercomputers, thus resulting in the construction of massive datacenters, and even, entirely new buildings (and hence, leading to an extraordinarily high total cost of ownership). Perhaps a more insidious problem to the above inefficiency is that the reliability (and usability) of these systems continues to decrease as traditional supercomputers continue to follow
