Abstract

PURPOSE:To virtually perform a load module by every load module by deciding a family to which the load module belongs from a corresponding directory information in the loading of the load module and loading the load module belonging to the family corresponding to the result. CONSTITUTION:A family identifier and a load module name are stored at a family identifier storing place 204 and a load module name storing place 203 by the first - the third load module storing means 110-112, and these are included in a directory entry 202, the load module being stored at a library 106. When the load module to be loaded is found within the library 106 resulting from the retrieving of the library, a load module retrieving means 103 starts up a switching means 104 of a load module loading means. The switching means 104 of the load module loading means decides the family to which the load module belongs by a family deciding means 105.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for virtualizing data processing devices in order to execute load modules created in data processing devices belonging to different families.

(Prior Art) Conventionally, this type of problem regarding the lack of compatibility of load modules between different families has been solved by realizing data processing devices belonging to different families on a virtual machine, and then has been solved by running load modules belonging to different families.

(Problems to be Solved by the Invention) In the conventional virtual machine method described above, a virtual machine corresponding to a data processing device of a different family is defined using system resources completely different from that of the current family, and this virtual machine Because data processing devices of different families are virtually created within the system, there are disadvantages in system operation such as the inability to share libraries between data processing devices of different families within the system, and load module execution problems. Load modules from different families cannot be mixed in the same address space, such as by dynamically loading another load module and executing it as a subroutine or as a separate task. There is a disadvantage in system development that existing load modules of different families cannot be used when developing a system.

An object of the present invention is to determine the family to which the load module belongs from the corresponding directory information when loading the load module, and to determine the family to which the load module belongs based on the corresponding directory information when loading the load module, in order to make it possible to virtually execute the load module for each load module. It is an object of the present invention to provide a virtual processor control method configured to eliminate the above-mentioned drawbacks by loading load modules belonging to a family, and to use existing load modules.

(Means for Solving the Problems) A virtual processor control system according to the present invention is configured to include a family determining means, a p-to module loading means, and a load module loading means selecting means.

The 7-family determining means is for determining the family to which the load module belongs from the corresponding directory information when loading the load module so that the load module can be executed virtually for each load module.

The load module loading means is for loading a load module belonging to a family.

The load module loading means switching means is for selecting an appropriate load module loading means from the load module loading means provided for each family according to the determination result of the family determining means.

(Example) Next, the present invention will be explained with reference to the drawings.

Referring to FIG. 1, an embodiment of the present invention includes a processor 101
, main storage device 102, and load module search means 1
03, load module loading means selection means 104, family determination means 105, library 106, load module loading means 107 to 109 provided for each of the first to third families, and the first to third seven families. It is composed of separately provided load module storage means 110 to 112. Here, 113 is a magnetic tape on which the load module is saved, and 114 is a magnetic disk on which the load module is stored.

Referring to FIG. 2, in the directory 201 included in the library 106, a directory entry 202 includes a load module name storage location 203 and a family identifier storage location 204 representing the family to which the load module belongs.

Next, the operation of the present invention will be explained with reference to the drawings.

The family identifier indicating the family to which the load module belongs and the load module name are stored in the first to third load module storage means 110 to 1 prepared for each family.
12 are stored in the family identifier storage location 204 and load module name storage location 203, respectively. These are included in the directory entry 202 and the load modules are stored in the library 106.

As a result of the library search by the load module search means 103, if a load module to be loaded is found in the library 106, the load module search means 103 activates the load module load means switching means 104.

The load module loading means switching means 104 uses the family determining means 105 to determine the family to which the load module belongs. When storing the load module in the library, the family determining means 105 determines the family to which the load module belongs based on the family identifier stored in the directory entry 202 together with the load module name. The load module loading means switching means 104 selects one of the first to third load module loading means 107 to 109 prepared for each family according to the determination result of the 7-ami IJ determining means 105, and thereby loads the load module. Module storage device 10
Load into 2.

(Effects of the Invention) As explained above, the present invention enables the data processing device itself to recognize the family to which the load module belongs based on the directory information of the load module, and virtualizes the data processing device for each load module. This has the effect of allowing the system to be operated without being concerned about compatibility and to develop the system using existing load modules.
