  • Non-blocking STMについて頑張って説明してみる - くまメモ

    STMはソフトウェアトランザクショナルメモリの略です。 ↓とりあえずwikipedia http://ja.wikipedia.org/wiki/%E3%82%BD%E3%83%95%E3%83%88%E3%82%A6%E3%82%A7%E3%82%A2%E3%83%88%E3%83%A9%E3%83%B3%E3%82%B6%E3%82%AF%E3%82%B7%E3%83%A7%E3%83%8A%E3%83%AB%E3%83%A1%E3%83%A2%E3%83%AA 日本でSTMの話題を検索すると「楽観的ロックでしょ？」といった発言を見かける事が多く、確かに実用的な手法の多くはロックベースだったりしていますが、正直なところロックベースな手法のSTMはデータベースでのトランザクションと似ているフシがあったりしてデータベースに詳しい人からするとそれほど驚くような手法ではない事が多いのです。その

            海外の文献を読み漁っていると気づくのですが 2003年を境にこの文脈で使われる言葉の定義が変わります。 ↑2003年ごろまでの構図 ↑現在の構図。*1 non-blocking = obstruction-free という理解でもおおよそ間違いではないとは思いますが 論文を読むに当たって non-blocking = ロックを使わないアルゴリズム全般 obstruction-free = 非lock-freeだけどロックだけはしない というニュアンスの違いを感じます。 以後、現在の構図の方を前提に話します。ご注意ください。 まずは3つの分類の違いから wait-free 操作が「他のスレッドの動向に関わらず有限ステップで完了できる」場合、そのアルゴリズムはwait-freeと呼ばれます。starvation-freeと呼んだりもします。 実際には初めからここに分類されるアルゴリズムは多くあ

                  Netpoll is a high-performance non-blocking I/O networking framework, which focused on RPC scenarios, developed by ByteDance. RPC is usually heavy on processing logic and therefore cannot handle I/O serially. But Go's standard library net is designed for blocking I/O APIs, so that the RPC framework can only follow the One Conn One Goroutine design. It will waste a lot of cost for context switching,

ActiveRecord is perfectly capable of using a number of different databases but MySQL is by far the most popular choice for production deployments.

                                In computer science, an algorithm is called non-blocking if failure or suspension of any thread cannot cause failure or suspension of another thread;[1] for some operations, these algorithms provide a useful alternative to traditional blocking implementations. A non-blocking algorithm is lock-free if there is guaranteed system-wide progress, and wait-free if there is also guaranteed per-thread pro

I say clunky because it's not bad, it's just not as easy to use as it could be. It's not as easy, for example, as the implementation found in Java's NIO package which is beautifully simple to use. The main issue I have with PHP's implementation is that I am responsible
