"XNNPACK" sample introduction

This sample demonstrates how to build XNNPACK benchmarks into WebAssembly with emcc toolchain and run them with iwasm.

Installation toolchains

• bazel. Please install bazel from latest release

• emsdk. Please install emsdk to /opt/emsdk:

cd /opt
git clone https://github.com/emscripten-core/emsdk.git
cd emsdk
./emsdk install latest
./emsdk activate latest

And set up ensdk environment:

source /opt/emsdk/emsdk_env.sh

Build XNNPACK

cd <wamr-dir>/samples/workload/XNNPACK
mkdir build
cd build
cmake ..

The wasm files are generated under folder samples/workload/XNNPACK/xnnpack/bazel-bin.

Run benchmarks

Firstly please build iwasm with simd, libc-emcc and lib-pthread support:

$ cd <wamr-dir>/product-mini/platforms/linux/
$ mkdir build && cd build
$ cmake .. -DWAMR_BUILD_SIMD=1 -DWAMR_BUILD_LIBC_EMCC=1 -DWAMR_BUILD_LIB_PTHREAD=1
$ make

And please build wamrc:

cd <wamr-dir>/wamr-compiler
./build_llvm.sh
mkdir build && cd build
cmake ..
make

Then compile wasm file to aot file and run:

$ cd <wamr-dir>/samples/workload/XNNPACK/xnnpack/bazel-bin
$ wamrc --enable-simd -o average_pooling_bench.aot average_pooling_bench.wasm  (or other wasm files)
$ iwasm average_pooling_bench.aot
