About Nanomsg
nanomsg is a socket library that provides several common communication patterns. It aims to make the networking layer fast, scalable, and easy to use. Implemented in C, it works on a wide range of operating systems with no further dependencies. This project has largely been superceded by the nng project. Users are encouraged to use nng if they are able. The nng project is wire compatible with this
Understanding the Internal Message Buffers of Storm
When you are optimizing the performance of your Storm topologies it helps to understand how Storm’s internal message queues are configured and put to use. In this short article I will explain and illustrate how Storm version 0.8/0.9 implements the intra-worker communication that happens within a worker process and its associated executor threads. Internal messaging within Storm worker processes Il

netcat for ØMQ. View the Project on GitHub zacharyvoase/zmqc Download ZIP File Download TAR Ball Fork On GitHub zmqc is a small but powerful command-line interface to ØMQ. It allows you to create a socket of a given type, bind or connect it to multiple addresses, set options on it, and receive or send messages over it using standard I/O, in the shell or in scripts. It's useful for debugging and ex

第1回 サイバーエージェント×グリー合同勉強会 〜合同勉強会の作り方〜 | GREE Engineering
はじめまして。GREEの開発本部の吉川(@tsuyoshikawa)と申します。 普段は内製のソーシャルゲーム開発を中心とした開発業務を行っています。 一ヶ月前くらいの7月27日(水)に、クローズドな開催ではありますが、株式会社サイバーエージェント様(以下敬称略とさせて頂きます)と合同技術勉強会を開催しましたので、レポートさせていただきます。 合同開催に至った経緯やその進め方といった、GREEなりの「合同勉強会の作り方」を公開してみたいと思いますので、ご意見や反響を頂くこと、あわよくば「GREEと合同勉強会やりたい！」という声を頂くことが本エントリのねらいでございます。 なお、このエントリはサイバーエージェントのエンジニアブログと相互リンクさせて頂いていますので、こちら「あわせて読みたい」ということでよろしくお願いいたします。 ⇒サイバーエージェント 公式エンジニアブログ また、勉強会の当

Nicholas Piël » ZeroMQ an introduction
ZeroMQ is a messaging library, which allows you to design a complex communication system without much effort. It has been wrestling with how to effectively describe itself in the recent years. In the beginning it was introduced as ‘messaging middleware’ later they moved to ‘TCP on steroids’ and right now it is a ‘new layer on the networking stack’.I had some trouble understanding ZeroMQ at first a
Routing with Ruby & ZeroMQ Devices - igvita.com
By Ilya Grigorik on November 17, 2010 ZeroMQ sockets provide message-oriented messaging, support for multiple transports, transparent setup and teardown, and an entire array of routing patterns via different socket types - see quick refresher on ZeroMQ. The combination of these features, as well as the fact that we can bind or connect a single socket to multiple endpoints is what makes ZeroMQ "top

DotCloud [1] is built from the ground up around distributed services. We use a custom rpc mechanism called ZeroRPC. It uses ZeroMQ [2] for transport, msgpack [3] for serialization, and some extra glue for RPC mechanics, discovery, event dispatching, etc.Among other neat tricks, it allows us to handle synchronous RPC calls and asynchronous message passing in a unified way. It also maps transparentl
Scalability Layer Hits the Internet Stack - 250bpm
Abstract This article argues that aside of TCP/IP (interlinked network hosts) and world-wide web (interlinked documents) we need a simple general-purpose decentralised infrastructure to interlink services. We will argue that the technical difficulty of connecting service providers and service consumers in a distributed fashion can be solved, and we will explain how we propose to solve it. We will
ZeroMQとfork(2)ではまった - fjnlの生存記録のような何か
僕はかなりはまったのですが、ZeroMQのcontextはfork(2)で複製できません。以下のようなコードを書くと死にます。forkする前にcontextを破棄するか、preforkしておく必要があります。 URLを忘れたのですが、MLでもpreforkしておいてよみたいな流れだったので、バグとかではなく、こういうものなのだと思います。 #include <iostream> #include <stdexcept> #include <zmq.hpp> #include <unistd.h> bool xfork() { pid_t const pid = fork(); if (pid == -1) { throw std::runtime_error("fork"); } return pid == 0; } int main() { zmq::context_t ctx(1);
Load balancing work between Java threads using ZeroMQ
If you ever wrote production multi-threaded server in Java you know how it is difficult to implement load balancing between worker threads. You need to fight many issues to have good load balancer: You need to limit somehow the number of worker threads, because with unlimited thread pool you can have memory exhausted. You need to implement sophisticated procedure for clean worker shutdown. If you
