The parallel implementations of the Barnes–Hut algorithm are tested for performance on shared memory multi-core architectures. The hardware-level performance analysis involving the parameters like the number of instructions executed by the CPU, level-1 and level-3 cache misses, and the number of ...
Ten years ago, while writing aphysics engine(opens in new tab), I learned about theBarnes-Hut algorithm(opens in new tab)for the gravitationaln-body problem(opens in new tab). Normally, computing the Newtonian gravitational forces between n bodies requires \(O(n^2)\) evaluations ofNewton’...

The new implementation uses vantage-point trees to compute sparse pairwise similarities between the input data objects, and it uses a variant of the Barnes-Hut algorithm - an algorithm used by astronomers to perform N-body simulations - to approximate the forces between the corresponding points in...
I have written a N-body simulator in Rust implementingBarnes Hut algorithmandLeapfrog integrator. My code seems to work fine, but I'd like to review on techniques which can improve performance while having the code be idiomatic rust. Ideally I'd like to know if there is something that would...

Barnes-Hut Algorithm A Rust implementation of the Barnes-Hut tree in 3 dimensions. This implementation focuses on the use of Rusts's enumerations to describe multiple coordniate systems, as well as the tree structure that forms the heart of the algorithm. ...
