A cluster manager usually is a backend graphical user interface (GUI) or command-line software that runs on one or all cluster nodes (in some cases it runs on a different server or cluster of management servers.) The cluster manager works together with a cluster management agent. These agents run on each node of the cluster to manage and configure services, a set of services, or to manage and configure the complete cluster server itself (see super computing.) In some cases the cluster manager is mostly used to dispatch work for the cluster (or cloud) to perform. In this last case a subset of the cluster manager can be a remote desktop application that is used not for configuration but just to send work and get back work results from a cluster. In other cases the cluster is more related to availability and load balancing than to computational or specific service clusters. ==Free and open source solutions== * (Apache Mesos ), from Apache Software Foundation * Keepalived, (keepalived.sourceforge.net ) * (Kubernetes ), backed by Google Inc * Linux Cluster Manager (LCM), (linuxcm.sourceforge.net ) * Heartbeat, from Linux-HA * oneSIS, from (onesis.org ) * Rocks Cluster Distribution, from (www.rocksclusters.org ) * SCMS.pro, from (www.scms.pro ) * (Stacki ), from (StackIQ ) * Ultra Monkey, from (www.ultramonkey.org ) * YARN, distributed with Apache Hadoop * xCAT () * Clinit () 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cluster manager」の詳細全文を読む スポンサード リンク
