- dnautics 7y agoI updated the Julia n body problem to use simd. It's actually really easy to read and I'm pretty confident it's very performant, but the problem is that for the number of iterations done, the VM boot time dominates. If you were doing a problem IRL, you would expect run times in the hours, and a 5 second vm load and program compile penalty would be peanuts.
- galangalalgol 7y agowhich implementation is that? 2 is the fastest but it doesn't use any .* or the like, an 3 which does and has "vectorised" in the comments is actually half the speed of 2
