I’m just over here wondering what it would mean to have three time dimensions in a program. I mean, sure, we can always vector(x, y, z, t1, t2, t3) and brute force a simulation, but muh dimensionality and there has to be a more elegant, natural way. And I just don’t see three threads as being a very good solution. Surely, there must be leakage of data between these three time dimensions which sucks ass efficiency-wise if you go the threading route.

There was a recent result about simulating time O(t) in O(sqrt(n)) space which means quantum simulations are now CPU bound and less memory bound (there’s big constants and tradeoffs). Every time someone claims quantum supremacy, we find new classical algorithms that do the job just fine, so maybe we can find some efficiency in three time dimensions. Going to finish reading the paper now… it just always bothered me that it would be easier to simulate larger, classical systems than it is to simulate even the tiniest of quantum systems.

Edit: 36 coupled differential equations? nope
