Gravitational N bodies simulation using Rust.

This repo contains an optimized Rust implementation of the N-Body simulation for x86 architectures.

Usage

RUSTFLAGS='-C target-cpu=native -Ctarget-feature=+avx512f' cargo +nightly build --release --bin opt

target-cpu: it depends on the architecture.
  
opt1: naive version
opt2: multi-threading version
opt3: fold version
opt4-3: math optimization version
opt5: Jemalloc version
opt6: block processing version
