MOSIX Grid and Cluster Management 2.21.2.6

MOSIX Grid and Cluster Management is a management system for Linux clusters and organizational grids that provides a Single-System Image.
In a MOSIX based system, there is no need to modify or link applications with any library, copy files, login to remote nodes, or even assign processes to different nodes; it is all done automatically. Just "fork and forget", like in an SMP.
Main features:
- Provides a Single-System Image (SSI).
- Automatic resource discovery.
- Adaptive workload distribution by process migration:
- Preserves the users "login-node" environment.
- No need to open "logins" or copy files to remote clusters.
- No need to link applications with special libraries.
- Automatic process migration:
- For load-balancing.
- From slower to faster nodes.
- When a node run out of free memory.
- Supports virtual organizations:
- Manages disruptive configurations:
- Clusters can join or leave the Grid at any time.
- Guest processes are moved out before a cluster is disconnected.
- Long-running guest processes are not killed.
- Clusters could be shared symmetrically or asymmetrically.
- Each cluster owner can assign different priorities to guest processes from other clusters.
- A flexible use of nodes within and among different groups.
- Local processes force out guest processes.
- A secure run time environment (sandbox) for guest processes.
- Live queuing - queued jobs preserve their full generic Linux environment.
- Support of batch jobs, checkpoint and recovery.
- An on-line monitor for the status of the Grid and each cluster.
Enhancements:
- This release uses version 2.6.22.3 of the Linux kernel.
