Question

It has been shown that Moore’s law not only applies to semiconductor density, but it also predicts the increase in (reasonable) simulation sizes, and the reduction in compu- tational simulation run-times. First show for a fluid mechanics simulation that takes 4 hours to run on a machine today, that it should only take 1 hour to run on machines built 3 years from now, and only 15 minutes on machines built 6 years from now. Then show that for a large simulation that has an estimated run-time of 5 years that it would complete sooner if we waited 3 years to start the simulation.

Explanation / Answer

As per the data given:

4 hours has come to 1 hour in 3 years and 15 min in next 3 years

So every 3 year time becomes 1/4th of the of the time.

So for an estimate of 5 years with current machine. it will become 1/4 *5 = 5/4 years
years if we start the simulation 3 years after.So definatly it wil take quite less
time as compared to 5 years.
