Treffer: The MOSIX Cluster Operating System for Distributed Computing on Linux Clusters, Multi-Clusters and Clouds
Weitere Informationen
MOSIX1 is a cluster operating system that provides users and applications with the impression of running on a single computer with multiple processors (single-system image). For example, in a MOSIX cluster users can run applications that create multiple processes, then let MOSIX seek resources and automatically distribute (migrate) processes among nodes, without changing the interface and the run-time environment of their respective login nodes. As a result, users need not change or link applications with any special library, they need not modify applications, login or copy files to remote nodes or even know where their programs run. Originally, MOSIX distributions for Linux-2.2 and Linux-2.4 were designed to manage a single cluster [3]. Starting from Linux-2.6 onwards, MOSIX was extended with a comprehen-sive set of features for managing clusters, multi-clusters, e.g.
