This does not affect a data center’s PUE but results in a loss of $30 billion in wasted electricity per year worldwide. One approach to dealing with this is distributed computing, which links computers to work as if they were a single machine. Scaling up the number of data centers that...
People differ in their willingness to take risks. Recent work found that revealed preference tasks (e.g., laboratory lotteries)—a dominant class of measures—are outperformed by survey-based stated preferences, which are more stable and predict real-wor
