⁠Taskflow | openEuler

Current Taskflow docker images are built on the openEuler⁠. This repository is free to use and exempted from per-user rate limits.

Taskflow helps you quickly write high-performance task-parallel programs with high programming productivity. It is faster, more expressive, fewer lines of code, and easier for drop-in integration than many existing task programming libraries.

Taskflow is header-only and there is no struggle with installation.

  int main(){
  
    tf::Executor executor;
    tf::Taskflow taskflow;
  
    auto [A, B, C, D] = taskflow.emplace(  // create four tasks
      [] () { std::cout << "TaskA\n"; },
      [] () { std::cout << "TaskB\n"; },
      [] () { std::cout << "TaskC\n"; },
      [] () { std::cout << "TaskD\n"; }
    );
  
    A.precede(B, C);  // A runs before B and C
    D.succeed(B, C);  // D runs after  B and C
  
    executor.run(taskflow).wait();
  
    return 0;
  }
