Проектирование распределенной системы с использованием только C
У меня есть работа по реализации распределенной системы узлов (например, узлов p2p), каждый из этих узлов (скажем, A, B, C и D) выполняет определенные функции и должен взаимодействовать друг с другом для различных операций, таких как синхронизация операции и другие вещи, такие как 15 узлов A, вз...
Java-эквивалент distcc
Distcc позволяет легко распределить задание компиляции C или C ++ между несколькими машинами и является находкой для работы с большими, часто создаваемыми базами кода. Однако в наши дни все больше наших крупных проектов строятся на Java.Кто-нибудь знает что-то эквивалентное или подобное для...

В чем основные различия между этими двумя технологиями?Есть ли у одного очевидные преимущества перед другим?
Как эффективно искать информацию об UUID в распределенной среде?
В настоящее время я разбиваю пространство UUID по модулю, поэтому для поиска данных не требуется пинговать каждый сервер.Однако основная проблема с модулем - это масштабирование, потому что добавление дополнительных узлов в хранилище данных, вероятно, потребует некоторой миграции данных.По вашем...
Изменение архитектуры базы данных с локальной на распределенную
У нашей компании есть продукт, работающий с использованием локальной базы данных (он позволяет большему количеству клиентов подключаться к одной базе данных и обмениваться данными между ними). СУБД : Microsoft SQL Server 2008 Теперь нам нужно создать единую базу данных, доступную через Ин...

Any ehcache standalone example projects I can download?
I'm a little overwhelmed reading through the ehcache user guide http://ehcache.org/EhcacheUserGuide.html#id.s20. I'm trying to figure out how to set up a simple ehcache app that has a distributed cache. I'd like to just run the app multiple times and have it share the cache between the multiple i...
Server-client Java distributed application
I have to design a distributed application composed by one server (developed in Java) and one or more remote GUI clients (Swing application with windows). As stated before the clients are Swing GUI application that can connect to the server in order to receive and send data. The communication is...
MPI overhead in shared memory setup
I want parallelize a program. It's not that difficult with threads working on one big data-structure in shared memory. But I want to be able to use distribute it over cluster and I have to choose a technology to do that. MPI is one idea. The question is what overhead will have MPI (or other tec...
.net service bus recommendations?
We are in need of a distributed architecture messaging system/service bus with the capability of Publish/Subscribe. Does anyone have any reccomendations for a framework that we can use for .net applications?
What are some scenarios for which MPI is a better fit than MapReduce?
As far as I understand, MPI gives me much more control over how exactly different nodes in the cluster will communicate. In MapReduce/Hadoop, each node does some computation, exchanges data with other nodes, and then collates its partition of results. Seems simple, but since you can iterate the ...
Anatomy of a Distributed System in PHP
I've a problem which is giving me some hard time trying to figure it out the ideal solution and, to better explain it, I'm going to expose my scenario here. I've a server that will receive orders from several clients. Each client will submit a set of recurring tasks that should be execu...

Real World Use of Zookeeper
I've been looking at Zookeeper recently and wondered whether anybody was using it currently and what they were specifically using it for storing. The most common use case is for configuration information, but what kind of data and how much data are you storing?
Keeping distributed databases synchronized in a unstable network
I'm facing the following challenge: I have a bunch of databases in different geographical locations where the network may fail a lot (I'm using cellular network). I need to keep all the databases synchronized but there is no need to be in real time. I'm using Java but I have the freedom to choos...
Is this a good canditate for a web-service?
Ok so coming in from a completely different field of software development, I have a problem that's a little out of my experience. I'll state it as plainly as possible without giving out confidential details: I want to make a server that "does stuff" when requested by a client on the same networ...
distribution transaction lock in oracle database
I have some question around transaction lock in oracle database. What I have found out so far is that: Cause: The time to wait on a lock in a distributed transaction has been exceeded. This time is specified in the initialization parameter DISTRIBUTED_LOCK_TIMEOUT. Action: This situation is tre...
Sequential numbers in distributed word
We are building order processing system. We have a cluster of processing servers. We need to assign readable numbers to the orders (e.g. ORD-000001, ORD-000002). Main problem that this is hard for us to implement system wide lock. I am thinking about schemas with lock expiration. But everything...
Distributed shared memory library for C++?
I am writing a distributed application framework in C++. One of the requirements is the provision of distributed shared memory. Rather than write my own from scratch (and potentially re-invent the wheel), I thought I would see if there were any pre-existing Open source libraries - a quick google ...
Distributed cache with expiration control in Java
The requirement is to cache a large number (100,000 to 1,000,000) of small objects and control the expiration of individual objects based on future events. There is no time component to the expiration. The cache must be available to a number of application servers (SpringSource dm Server) and i...
Looking for a framework for logging arbitrary objects in heavily distributed and parallelized system in .NET
(Note: I have seen several questions regarding .NET logging frameworks, but haven't seen any which resembles our requirements. So please don't close this one as a duplicate.) We will need a logging framework for a highly distributed and parallel .NET application with the following features: ...
What are the pros and cons of PyRo and RPyC python libs?
I am looking for a remote procedure call engine for Python and I've found that PyRo (Python Remote Object) and RPyC (Remote Python Call) are both the kind of thing I am searching for. However, I am curious to know how they compare to each other and what are their pros and cons ?
Observer in a distributed environment
Machine A needs to send a message to machine B. Machine A has a static IP but machine B does not. One option I could think of to solve this problem is that machine B opens a TCP connection to machine A and then machine A sends the data/message to machine B. However, this solution has the followi...
Can you send messages using MSMQ to a machine not in the same domain?
I haven't read enough about or used MSMQ till now. For many years now, I've only known that they exist. So, forgive me if my question indicates lack of rudimentary knowledge on the subject. If I have to send a message from machine A to machine B, but they are not on the same network, is it possi...
distributed caching on mono
I'm searching for a distributed caching solution on mono similar to java's terracotta and infinispan. I want to use it as a level 2 cache for nhibernate. Velocity and sharedcache have no mono support, and memcached isn't distributed nor have high availability. Best Regards, sirmak
calculate object delta
I am working on an application where client and server share an object model, and the object graphs can become rather big. To save an object from client to server, ideally i would like to send only the difference over the wire, to minimize network traffic. I can pull the original object graph on...
Picking a port for listening to a response/keeping socket open?
I've got a client app which has to connect to a server and register for waiting, that is, it wants to be notified when the server is done with some processing. Ideally, I want to keep this client as simple as possible, but the question is, how to "register for waiting". I could keep the socket op...
