README

This app is a demo of using the Halide webassembly backend

To try it out,

• install emscripten (see emscripten.org), and have emcc in your path.

• Build with make all

• Run a local webserver using, e.g.: python3 -m http.server 8080 &

• Load Google chrome (at least version 84), go to chrome://flags, and turn on all the experimental webassembly stuff (e.g. threads, simd). If you don't do this, only the single-threaded scalar variant will work (at the time of writing).

• Visit http://127.0.0.1:8080/index.html

• Finally, run make benchmark_native and compare the performance you get with native code
