- Xgrid is a proprietary software program and distributed computing protocol developed by the Advanced Computation Group subdivision of Apple Inc that allows networked computers to contribute to a single task. The system has been used by researchers using MacResearch's OpenMacGrid. It provides network administrators a method of creating a computing cluster, which allows them to exploit previously unused computational power for calculations that can be divided easily into smaller operations, such as Mandlebrot maps. The setup of an Xgrid cluster can be achieved at next to no cost, as Xgrid client is pre-installed on all computers running Mac OS X 10.4 or later. The Xgrid controller, the job scheduler of the Xgrid operation, is also included within Mac OS X Server and as a free download from Apple. The program employs its own communication protocol layered on top of a schema to communicate to other nodes. This communication protocol interfaces with the BEEP infrastructure, a network application protocol framework. Computers discovered by the Xgrid system, that is computers with Mac OS X's Xgrid service enabled, are automatically added to the list of available computers to use for processing tasks. When the initiating computer sends the complete instructions, or job, for processing to the controller, the controller splits the task up into these small instruction packets, known as tasks. The design of the Xgrid system consists of these small packets being transferred to all the Xgrid-enabled computers on the network. These computers, or nodes, execute the instructions provided by the controller and then return the results. The controller assembles the individual task results into the whole job results and returns them to the initiating computer. Apple modeled the design of Xgrid on the Zilla program, distributed with NeXT's OPENSTEP operating system application programming interface, which Apple owned the rights to. The company also opted to provide end users with only command-line functions and little flexibility, while giving only the Mac OS X Server version of Xgrid a GUI control panel and a full set of features.
- Xgrid ist ein Konzept des Grid Computings und verteilten Rechnens, welches von der Firma Apple Inc. für das Betriebssystem Mac OS X entwickelt wurde. Die Lösung zeichnet sich durch einfache Konfigurierbarkeit und vollständig implementierten Support durch das Betriebssystem aus. Inzwischen gibt es auch Lösungen, mit denen sich auch andere Systeme in Xgrid integrieren lassen
- Xgrid est une API logiciel développé par le Apple's Advanced Computation Group qui permet à un groupe d'ordinateurs en réseau d'effectuer du calcul distribué. Le but d'Xgrid est de permettre (aux scientifiques notamment) d'exploiter à bas prix des ressources de calcul inutilisées. Il fonctionne comme un planificateur de tâches, et répartit les tâches que chaque ordinateur disponible doit effectuer. En intégrant Xgrid à Tiger, Apple a accru son accessibilité; toutefois seul Mac OS X Server est livré avec une interface graphique de contrôle de Xgrid. Les versions non-serveurs doivent utiliser les programmes en ligne de commande xgridctl et xgrid.
- Xgrid è una tecnologia sviluppata da Apple Computer per il sistema operativo Mac OS X. Lo scopo di questa tecnologia è consentire lo sviluppo di applicazioni parallele che distribuiscono le operazioni da eseguire su più macchine collegate da una rete telematica riducendo i tempi necessari all'elaborazione.
- Xgrid(エックスグリッド)とはアップル社が製作したMac OS X Server, Mac OS X用の分散コンピューティング/コンピュータ・クラスター環境。 ローカルネットワーク及びインターネットを介して複数台のMacに計算作業を分担させる事が可能。Bonjourテクノロジーを用いて、ネットワーク上で主コントローラのマシンがエージェントとして使えるマシンを自動検知することができる。 Mac OS X v10.3 以降で動作し、Mac OS X Server/Mac OS X v10.4から標準機能として搭載されている。 アメリカ合衆国内では、安価かつ容易にグリッド・コンピューティングを実現できるシステムとして主に大学の研究機関の間では人気が高まっている。
- Xgrid — технология, разработанная компанией Apple, позволяющая объединять группу компьютеров в виртуальный суперкомпьютер для проведения распределенных вычислений. Технология Xgrid была представлена на выставке MacWorld Expo в Сан-Франциско, 6 января 2004 года.
