A WASM workbench for the n-body scenario.
- Node.js installed (v. 10+ for async/await support)
- Emscripten installed
- Rust installed
- wasm-pack installed
First, install the development dependencies:
$> npm install
Now, to build assembly/index.ts to an untouched and an optimized .wasm including their respective .wat representations, run:
You will need emscripten installed on your machine (for C → WASM)
$> npm run build
To run the benchmark:
$> npm run test
To run the native test benchmark (optimized C agains nodejs)
$> npm run testnative
To run the browser test benchmark
$> npm run browserbuild
$> npx serve
Open the browser and point it to localhost:5000

Wants to test that new shiny SIMD support in WASM?
We got you covered: install the required tools and follow the instructions in ./C/build.sh to enable it.
Wants to try out this benchmarks? Cool, try them out and let us know the numbers!
