With the advent of computer networks, in which many computers are linked together and are able to communicate with one another, distributed computing became feasible. A distributed computation is one that is carried out on more than one machine in a cooperative manner. A group of linked computers working cooperatively on tasks, referred to as a distributed system, often requires a distributed operating system to manage the distributed resources. Distributed operating systems must handle all the usual problems of operating systems, such as deadlock. Distributed deadlock is very difficult to prevent; it is not feasible to number all the resources in a distributed system. Hence, deadlock must be detected by some scheme that incorporates substantial communication among network sites and careful synchronization, lest network delays cause deadlocks to be falsely detected and processes aborted unnecessarily. Interprocess communication must be extended to processes residing on different network hosts, since the loosely coupled architecture of computer networks requires that all communication be done by message passing. Important systems concerns unique to the distributed case are workload sharing, which attempts to take advantage of access to multiple computers to complete jobs faster; task migration, which supports workload sharing by efficiently moving jobs among machines; and automatic task replication at different sites for greater reliability.
