 Mosix and the things taht you do are complementary. Mosix can't migrate a
process BEFORE executing it, and you can'tmigrate after executing. This
menas that if you do 100 forks in Mosix, you will have the 100 process
running at their home node when they run in kernel level. By other way, if
you have 20 process in 10 nodes and in 5 nodes all process finished, you
can not migrate the running 10 process that overloads 5 nodes to the 5
wasted nodes. That is what mosix does well. I thing that the two works are
complementary, because each one do things that de other do not do.

 Yours:

David
