And, as it did in 1972, virtual memory gives you the effect of about twice as much real memory. Back then, a megabyte of memory cost about a million dollars. Today, a gigabyte of memory costs about five dollars. Why are we still bothering with paging?
We used it to enable analyzing trillion particle dark matter simulations a halo at a time, as though they were local. It was fun. We made it part of the way into implementing an fopencookie version, but ended up moving on to other projects.
Very cool! There's a slight difference in the replacement strategy, though: the narrator said that this one places the most recently zarked things on the top.
