Overview

MOSIX^* is an operating system like management system targeted for high performance computing on Linux clusters and multi-clusters. MOSIX incorporates dynamic resource discovery and automatic workload distribution, commonly found on single computers with multiple processors. In a MOSIX system, users can run applications by creating multiple processes, then let MOSIX seek resources and automatically migrate processes among nodes to improve the overall performance, without changing the run-time environment of migrated processes.

MOSIX is implemented as a software layer that provides to users and applications with an unmodified Linux run-time environment. As a result, users do not need to modify or link applications with any library, login to remote nodes or even copy files to remote nodes.

MOSIX Version 1 was originally developed to manage a single cluster. MOSIX Version 2 (MOSIX2) for Linux-2.6 was extended with a comprehensive set of new features that can manage clusters and multi-clusters.

For further information see the Latest release and changelog, the MOSIX2 white paper, our CCGrid papers, the Overview of MOSIX2 presentation, the MOSIX2 Tutorial and the HUGI campus multi-cluster.
