Metamodel of paralelism. At this time, there is not any aplication that uses it. Legion is an attempt to build a true multicomputer system. That is a cluster whereby each node is an independent system, but the overall system appears to the user as a single computer, as Mosix inteeds; but Legion was designed to support a single worldwide computer consisting of many hosts and many software objects. Within Legion, users can construct their own collaborative groups. On its theoretical side, Legion provides high-performance parallelism, load-balancing, distributed data management, and fault-tolerance. It supports high-availability through its fault-tolerance management and dynamic reconfiguration across the member nodes. It also has an extensible core that can be dynamically replaced or upgraded over time as new advancements or developments arise. The system is not under a single monolithic control but can be managed by any number of organizations, each supporting an autonomous part of the whole. The Legion API provides high-performance computing through its built-in parallelism.
All this stuff rely over the user's computer operating system and negotiates between the local and the distributed resources. It handles resource scheduling and security automatically and also manages a context space to describe and access any object out of all of the possibilities in the entire system. However, it does not need to run under system administrator privileges on each node and can work within the confines of a nonprivileged user account. That increases the flexibility of the nodes and users that can join Legion.
This is what Legion team says. At this time, there is not any application, neither real nor toy, over legion.
