WASM Support
oneTBB extends its capabilities by offering robust support for WASM.
WASM stands for WebAssembly, a low-level binary format for executing code in web browsers.
It is designed to be a portable target for compilers and efficient to parse and execute.
Using oneTBB with WASM, you can take full advantage of parallelism and concurrency while working on web-based applications, interactive websites, and a variety of other WASM-compatible platforms.
oneTBB offers WASM support through the integration with Emscripten*, a powerful toolchain for compiling C and C++ code into WASM-compatible runtimes.
Build
Prerequisites: Download and install Emscripten*. See the instructions.
To build the system, run:
mkdir build && cd build
emcmake cmake .. -DCMAKE_CXX_COMPILER=em++ -DCMAKE_C_COMPILER=emcc -DTBB_STRICT=OFF -DCMAKE_CXX_FLAGS=-Wno-unused-command-line-argument -DTBB_DISABLE_HWLOC_AUTOMATIC_SEARCH=ON -DBUILD_SHARED_LIBS=ON -DTBB_EXAMPLES=ON -DTBB_TEST=ON
To compile oneTBB without pthreads, set the flag -DEMSCRIPTEN_WITHOUT_PTHREAD=true in the command above. By default, oneTBB uses the pthreads.
cmake --build . <options>
cmake --install . <options>
Where:
emcmake- a tool that sets up the environment for Emscripten*.-DCMAKE_CXX_COMPILER=em++- specifies the C++ compiler as Emscripten* C++ compiler.-DCMAKE_C_COMPILER=emcc- specifies the C compiler as Emscripten* C compiler.
NOTE: See CMake documentation to learn about other options.
Run Test
To run tests, use:
ctest
