A method of fault tolerance in a multiprocessor system based on primary-backup scheme includes: receiving a task to be allocated to a processor in a multiprocessor system; allocating a primary version of the task according to a normal real-time scheduling algorithm; checking validity of the allocation of the primary version of the task; allocating a backup version of the task with overloading; and checking validity of the allocation of the backup version of the task.
