Abstract
A multi-processor system has a main memory shared by a plurality of processors, two operating systems, a local supervisor for executing processing in a local area and a global supervisor for executing processing which requires access to a common area. When the local supervisor needs processing which requires access to an area other than the local area, it requests that execution of the processing be effected by the global supervisor. Thus, the local supervisor executes the processing only in the local area. More than one processor will do not simultaneously execute processing in one local area.
