"XNNPACK" sample introduction
|
||
|
|
==============
|
||
|
|
This sample demonstrates how to build [XNNPACK](https://github.com/google/XNNPACK) benchmarks into WebAssembly with emcc toolchain and run them with iwasm.
|
||
|
|
|
||
|
|
## Installation toolchains
|
||
|
|
|
||
|
|
- **bazel**. Please install bazel from [latest release](https://github.com/bazelbuild/bazel/releases)
|
||
|
|
|
||
|
|
- **emsdk**. Please install [emsdk](https://github.com/emscripten-core/emsdk) to /opt/emsdk:
|
||
|
|
```bash
|
||
|
|
cd /opt
|
||
|
|
git clone https://github.com/emscripten-core/emsdk.git
|
||
|
|
cd emsdk
|
||
|
|
./emsdk install latest
|
||
|
|
./emsdk activate latest
|
||
|
|
```
|
||
|
|
And set up ensdk environment:
|
||
|
|
```bash
|
||
|
|
source /opt/emsdk/emsdk_env.sh
|
||
|
|
```
|
||
|
|
|
||
|
|
## Build XNNPACK
|
||
|
|
|
||
|
|
```bash
|
||
|
|
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:
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
$ 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:
|
||
|
|
|
||
|
|
``` bash
|
||
|
|
cd <wamr-dir>/wamr-compiler
|
||
|
|
./build_llvm.sh
|
||
|
|
mkdir build && cd build
|
||
|
|
cmake ..
|
||
|
|
make
|
||
|
|
```
|
||
|
|
|
||
|
|
Then compile wasm file to aot file and run:
|
||
|
|
|
||
|
|
``` shell
|
||
|
|
$ 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
|
||
|
|
```
|
||
|
|
|
