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 . http://en.wikipedia.org/wiki/Self-stabilization http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.88.4096&rep=rep1&type=pdf http://search.yahoo.com/search;_ylt=A03uoRZ7YbpLwjUB8W.bvZx4?p=self+stabilization&toggle=1&cop=mss&ei=UTF-8&fr=yfp-t-701 www.selfstabilization.org http://en.wikipedia.org/wiki/Load_balancing_%28computing%29 http://en.wikipedia.org/wiki/Category:Fault_tolerance http://en.wikipedia.org/wiki/Category:Reliability_engineering http://en.wikipedia.org/wiki/Category:Distributed_computing 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 www.mozart-oz.org *Mozart is available as a FreeBSD port. *Thank you very much . Mehmet Erol Sanliturk
