C++メモリモデル

1.10 Multi-thread executions and data aces

  • Thread of execution (or thread) は flow of control のひとつ.
    • 特定のトップレベル関数の呼び出しを含む．
    • そのスレッドが呼び出す関数をすべて含む．
    • どのスレッドも潜在的にはプログラム内のすべてのオブジェクトと関数にアクセスする可能性がある．
    • C++プログラムは複数のスレッドを並列に実行できる．
  • 処理系はすべての unblocked なスレッドが eventually make progress することを保証すべき．
