I have been able to extract some 100000 cpu hours overall from a cluster of
workstations, by using (open)Mosix on it. Since they are mostly used for
interactive tasks, I could run a number of very low priority long
calculations on my computer, from which they would automagically get
migrated over free nodes and back to my computer when they were being used
(i.e. when the local user ran a command which required some cpu power).
Great for me. Probably useless for a dedicated cluster.
