MOSIX

Mosix, Multi-computer Operating System for Unix, è un sistema di gestione di cluster Linux che ne potenzia le capacità del kernel offrendo "cluster capabilities" e griglie organizzative. Il sistema fornisce una Single-system image (SSI), in altre parole la capacità di vedere un sistema composto da più macchine fisiche come un'unica macchina virtuale. Consente la migrazione dei processi da un nodo all'altro del cluster in modo automatico e trasparente, garantendo tutte le funzionalità dei comandi di controllo dei processi Linux senza costringere gli sviluppatori a riscrivere le applicazioni in modo da gestire la suddivisione dei processi in sottoprocessi indipendenti che possano essere eseguiti su processori differenti. Permette inoltre di accedere a librerie remote come se fossero sulla macchina locale automaticamente ed in modo trasparente per l'utente finale.

Questi articoli descrivono i metodi per la gestione delle griglie, inclusa la gestione delle configurazioni dinamiche, gli algoritmi di gossip per la disseminazione delle informazioni, i nodi di tipo Fair-shareper l'allocazione dei nodi in una griglia e la migrazione massiva dei lavori da un cluster in via di disconnessione.
