Example 2: Taichi Arch

An arch is an execution backend of Taichi Runtime. Depending on build-time flags and current platform installation, Taichi Runtime can support one or more archs. You can use get_available_archs to enumerate all the archs available in the current environment.

std::vector<TiArch> archs = ti::get_available_archs();

std::cout << "the following archs are supported:" << std::endl;
for (TiArch arch : archs) {
  switch (arch) {
  case TI_ARCH_VULKAN:
    std::cout << "- vulkan" << std::endl;
    break;
  case TI_ARCH_METAL:
    std::cout << "- metal" << std::endl;
    break;
  case TI_ARCH_CUDA:
    std::cout << "- cuda" << std::endl;
    break;
  case TI_ARCH_X64:
    std::cout << "- x64" << std::endl;
    break;
  case TI_ARCH_ARM64:
    std::cout << "- arm64" << std::endl;
    break;
  case TI_ARCH_OPENGL:
    std::cout << "- opengl" << std::endl;
    break;
  case TI_ARCH_GLES:
    std::cout << "- gles" << std::endl;
    break;
  default:
    break;
  }
}

The above C++ code may give the following output:

the following archs are supported:
- metal
