Calculate answers to the following short-answer questions on technology and its future, consulting hardware specifications or documented performance summaries as needed.
Include error bars wherever feasible when answering these questions.

1) Determine the doubling time for the fastest supercomputers over a 10 year span.

2) Calculate the bandwidth difference between the fastest memory bus and the fastest disk drive.

3) How many drives (and of what type) would be required to keep up with Intel's Larrabee
many-core processor if all of its cores wrote I/O at maximum rates?

4) What is the highest power efficiency (defined as Watt per double-precision FLOP) among
CPUs currently available and GPUs currently available?
