Sleep Sortでマルチスレッド比較(js/TS/VB/C#/C++/D/Go/HSP(mist))

Last updated at Posted at 2016-11-14

概要

  • 最近PromiseとかTaskとかThreadとかいくつかの処理系の非同期処理を学んだのでその対比としてSleepSortの書き比べ。
  • jsとTS、VBとC#はどうしても似通るのでそれぞれAsync/Await使用版、未使用版で分割。
    (TSとC#でAsync/Awaitを使用する)
  • HSPはそもそもマルチスレッド非対応なのでexeファイル分割してのゴリ押し対応。※参考
  • 2016/11/16 HSP mistの魔力に魅せられてSreepSort追加。
  • 2016/12/10 C++、Go言語追加。タグ? 知らないなぁ。タグ数足らん

補足

  • D言語のThreadはPromise.raceやWaitAny, WhenAnyに対応する構文がなさそう。
    この処理が必要になるケースがわかっていないけど、isRunningを観測していればいいのかな。
//tg As ThreadGroup
joinAny:for(;;){
	foreach(t;tg)if(!t.isRunning)break joinAny;
}

  多分こんな感じで。

  • D言語のreplaceの使い方がわからない。
    あとはreadlnでLFも持ってくるっぽいので文字処理必須。
  • HSPのマルチスレッドもどきはtxtファイルで待ち合わせしてるのでそのファイルに万一何か起きればバグる。
    そのためとりあえずTimeOutできるように小細工。
    • 自分自身をexecで起動するように修正して単一化。
      また、一時ファイルを%TEMP%フォルダに配置するようにして優しく隠蔽。
  • mistの魔力やばい。プラグインなのでdll(hpi)が別途必要になるけど、命令や関数が色々な形で起動できるので夢広がる。ラムダ式とかクロージャみたいな使い方もできる。一括処理だけだけどマルチスレッドにも対応してる。でも、mist空間内ではプリプロセッサ命令使えないので拡張が若干効かない部分もあるのかな。wait、awaitがmist空間内ではスレッド回してても同期処理になってしまうので代替の方法を探したけど、HSP標準のgetTime関数で再実装することしか思いつかなかった。
    • mistプラグイン作者のえくーさんにmstCaptDll命令の存在を教えて頂いた。これを使用することでmist空間内にfuncで定義したdll関数を適用できるみたいだ。ただ、その関数が読み込まれる条件がちょっとわからなくてsleepを適当なところで空撃ちさせている。
