"codecbench of meshoptimizer" sample introduction

This sample demonstrates how to build codecbench of messoptimizer into WebAssembly with simd support and run it with iwasm.

Preparation

please refer to installation instructions.

Build with wasi-sdk

$ mkdir build && cd build
$ cmake ..
$ make
# to verify
$ ls codecbench.wasm

Or build with EMSDK

EMSDK is another toolchain to compile C/C++ code to WASM. In this case, the output wasm file might have a higher performance than the file generated by wasi-sdk.

$ git clone https://github.com/zeux/meshoptimizer.git
$ cd messoptimizer
$ em++ tools/codecbench.cpp src/vertexcodec.cpp src/vertexfilter.cpp \
       src/overdrawanalyzer.cpp src/indexgenerator.cpp src/vcacheoptimizer.cpp \
       src/clusterizer.cpp src/indexcodec.cpp src/vfetchanalyzer.cpp \
       src/spatialorder.cpp src/allocator.cpp src/vcacheanalyzer.cpp \
       src/vfetchoptimizer.cpp src/overdrawoptimizer.cpp src/simplifier.cpp \
       src/stripifier.cpp -O3 -msimd128 \
       -s TOTAL_MEMORY=268435456 \
       -o codecbench.wasm
$ ls -l codecbench.wasm

Run workload

Firstly please build iwasm with simd support:

$ cd <wamr dir>/product-mini/platforms/linux/
$ mkdir build && cd build
$ cmake ..
$ make

Then compile wasm file to aot file and run:

$ <wamr dir>/wamr-compiler/build/wamrc -o codecbench.aot codecbench.wasm
$ <wamr dir>/product-mini/platforms/linux/build/iwasm codecbench.aot
