RAM and the degrees of freedom This question is about computation/computational physics.

Imagine that you want to solve $10^6$ equations of motion, and you have $10^6$ degrees of freedom (position of the particle).

How many RAM memory would you need (theoretically) to do this?

(I am not interested in the final answer, I am just interested in the thinking of estimate this.)

Thank you
As a first approximation, most of the memory will be spent on storing $10^6$ floating point numbers (one per degree of freedom). Assuming double precision numbers are used, each number takes up 8 bytes, for a total of 8MB.
