In a multiprocessor system, the operating system is structured such that there is a local operating system per processor (36-39, 42-44, 61-66), a group operating system (21) per group of processor (31-33) and a global operating system (22) per system. Each operating system is independent and refers to a higher level operating system only if its local processing ability is exceeded, Each group operating system (21) is allocated as a task to at least one of the processors in its group (31-33) and the global operating system (22) is allocated as a task to one of the groups within the system (21). The higher order operating systems have the ability to reschedule resources by reallocating the function of particular processor units. A system having more than three levels of operating system may be provided. |
