Abstract

PURPOSE:To reduce the hardware cost by making plural virtual computer systems share the real resources. CONSTITUTION:An application program is controlled by a virtual multiple processor 4 via either one of virtual computer systems 1-3 and an execution mode is controlled by an execution mode controller 6. In an on-line mode, the resources of the systems 1-3 have the free input/output in response to the real resources 25 and 26 via a resources/real resources correspondence controller 7. In a test mode the resources are limited to the virtual resources 23 and 24 and the input/output is cut off to the resources 25 and 26. In a parallel run-on mode the systems 1-3 themselves have no change from the on-line mode and the resources of the systems 1-3 go to the resources 23 in terms of the output in a parallel run test mode, then go to the resources 25 in terms of the input respectively. Thus the computer system cost is reduced.
