Why MOSIX?

From users' point of view, the 6 computers appear as a single computer with 12 processors.
MOSIX supports job-level parallelization:
- Users do not have to rewrite their code in order to take full advantage of the cluster; they simply run several jobs at once.
MOSIX doesn't support fine-grain parallelization, e.g., multiplying a huge matrix quickly using lots of nodes of a network. Thus MOSIX isn't good for weather forecasters.
