this is real cool but take note of the work processes. it migrates
"processes". for a parallel compute job that may not be enough due to the
inefficiencies of having to rely on mosix process migration. however, i
have some interesting uses for mosix in production environs.
some practical and interesting uses:
-parallel compute farms. since each bash/sh/tcsh or any other shell can be
migrated, this will enable a school or company to create a programmers
compute farm with mosix enabled computers
-parallel threaded java applications (used green thread kasi user space
threads are system processes and this can be migrated by mosix. althrough,
speed up may not be worth it for some applications)
needs very good network interconnection though.
