Abstract

MOSIX is a cluster management system that uses process migration to allow a Linux cluster to perform like a parallel computer. Recently it has been extended with new features that could make a grid of Linux clusters run as a cooperative system of federated clusters. On one hand, it supports automatic workload distribution among connected clusters that belong to different owners, while still preserving the autonomy of each owner to disconnect its cluster from the grid at any time, without sacrificing migrated processes from other clusters. Other new features of MOSIX include grid-wide automatic resource discovery; a precedence scheme for local processes and among guest processes (from other clusters); flood control; a secure run-time environment (sandbox) which prevents guest processes from accessing local resources in a hosting system, and support of cluster partitions. The resulting grid management system is suitable to create an intra-organizational high-performance computational grid, e.g., in an enterprise or in a campus. The paper presents enhanced and new features of MOSIX and their performance.
