There is a concept : Self-stabilization .

There will be a ring of computers working simultaneously . If any one of
them fails , others will continue to handle tasks requested from those
systems . Such a ring may utilize load-balancing to distribute work load to
currently working computers .

Actually , FreeBSD itself is an operating system : It manages single
computers . You need other software to handle distributed computing . Such a
language among others is
