Description

DETAILED DESCRIPTION OF THE INVENTION (4) Technical field of the invention The present invention provides a multiprocessor system using a virtual computer system, particularly in a conventional virtual computer system, a virtual computer region allocated to a predetermined virtual computer region on a real main memory. This has improved the point that only the virtual computers assigned to any virtual machine region can configure the Hoshinashi X machine system and the multiprocessor system. The present invention relates to a multi-processor system using a virtual computer system that is capable of configuring.

(B) Technical Background In the late 1960s, the concept of a "virtual computer" was conceived, and attempts to put it into practical use were made, causing a stir. The benefits of "virtual computers" can be summarized into the following two things.

Multiple users using a prison computer system.

Aku can be realized using t1 pieces of hardware in an environment in which he has exclusive access to the computer system.

(B) A computer system with a slightly different architecture or a slightly different system configuration can be virtually created.

Therefore, by using a virtual machine, it is possible to run programs running under different operating systems (hereinafter referred to as O8) at the same time, and the system configuration can be changed more flexibly. . It is also possible to monitor the operating status of the system, and the debugging functions provided in the computer can be used for various needs.

FIG. 81 shows a conceptual diagram of a conventional computer system, and FIG. 2 shows a conceptual diagram of a virtual computer system.

The actual computer here is computer hardware.

O8 uses computer resources (CPU, main memory, channels,
Input/output control devices, human output devices, system controllers, etc.) are managed so that each program shares them. A conceptual interface called a hardware interface is set up between the computer and the actual computer. Further, an interface called a user program 108 interface is set up between the needs program and the needs program. In the case of a virtual machine, a program called a virtual machine monitor (VMM) manages system resources so that each program can share them.

In FIG. 2, VM #0 surrounded by a dotted line,
VM#Information corresponds to a conventional computer system and is called a VM (virtual machine), and multiple VMs can be run simultaneously under a virtual machine.

Today, multiprogramming technology is used to efficiently operate computer systems, and each program shares system resources. Therefore, these system number resources are managed by the operating system (O
a) Individual user programs that can access these system resources by instructions that can only be issued by O8, usually referred to as "privileged instructions", are assigned "unprivileged mode". When a user program issues the aforementioned "privileged instruction", a program interrupt called a "privileged instruction exception" is detected.

In the case of virtual machines, it is possible to run a plurality of conventional O8s at the same time, and therefore the system resources that were managed by conventional O8s are managed by a program called a virtual machine monitor (VMM).

All of the programs of each user, including the 08 being used, are assigned "non-privileged mode 1", and only the VMM operates in "privileged mode 4". Therefore, when the 08 used by each user attempts to execute the "l privileged instruction, a program interrupt is detected.

Execution control is passed to the VMM, and the VMM synchronizes this "privileged instruction."

Although the virtual computer system is configured as described above, there are limitations when combining such a virtual computer system with a thin computer system and a multiprocessor system configuration. That is, in the virtual computer system, each VM is assigned and associated with a virtual computer region on the wage storage, but the VMs that can configure the thin needle computer system and the multiprocessor system are general K.
It was limited only to those assigned to a region called VR. This is because when the above-mentioned thin needle computer system attempts to access a virtual machine region other than VR, it requires address translation and cannot be accessed without intervening the above-mentioned VMM, and in the end, it cannot access the virtual machine region other than VR. This may be because the virtual machine region cannot be accessed.

Prior to the present invention, in a virtual machine such as the one described above, KL and each VM were assigned to a virtual machine region of V-H so that the content of the base register was accessed by "getting it out" corresponding to each VM. A method has been developed that allows the device to operate as if it were installed.

(C1 Object and structure of the invention The present invention provides a system for each VM in the above-mentioned new type of virtual machine.
The present invention aims to enable any VM to configure a multi-glossary system by paying attention to the fact that the VM is essentially allocated to a virtual machine region where V=H. Therefore, the multiprocessor system using the virtual computer system of the present invention is provided with a management program for operating a plurality of operating systems in parallel on one computer system, and the plurality of operating systems are provided with a management program that allows the plurality of operating systems to operate in parallel on one computer system. In contrast to a virtual computer system in which each computer performs processing under the management of Each operating system is assigned to a different virtual machine region on the real main memory using the base register to configure a virtual machine, and the operating systems of the Joki and other computer systems are allocated on the real main memory. A dedicated processor area is created for the processor area, and the computer system is configured to be controlled by the contents of the processor area, and the other computer system is configured to control the actual storage based on the contents of the processor area. The present invention is characterized in that the virtual machine system and the multiprocessor constitute a system in a designated one of the above virtual machine regions.

This will be explained below with reference to the drawings.

(To) Embodiment of the Invention Figure 3 shows an explanatory diagram conceptually explaining the configuration of an embodiment of the present invention. -1 to 2-4 are respectively V
M, 3 is a base register, which performs "gekuhakase" according to its contents and associates each VM with a region in the real main memory, 4 is the real main memory, and 5 is the advanced C percha JL/@ "ef Thin (Music VM) control program included in the VMM shown in FIG. 1 to 7-4 each represent a virtual computer region, 8-1. ing.

The virtual computer system accesses the VM control program 5 and performs the following based on the contents of the base register 3.
Each VM is controlled to execute processing while accessing its corresponding virtual machine region 7-1 to 7-4 on the real main memory 4.

In the present invention, in order to configure a multiprocessor system, dedicated processor areas 6-1 and 6-2 are prepared corresponding to each fine needle calculator system 8-1 and 8-2. For example, a program associated with the axis counter system 8-IK is stored in the dedicated processor area 6-1. When the thin needle computer 8-1 configures a multiprocessor system with VM 2-2, for example, the virtual machine region 7-2 is stored on the base register 10-1.
The first address person D2 is set, and the detailed calculation IM
S-1 performs "getting" based on the contents of the base register 10-1 and transfers it to the virtual machine region 7-2.
Contains a group of instructions for accessing the .

For this purpose, the detailed calculation [8-1 is performed by the dedicated processor area 6
Using the contents of -1, the above base register 10-1
It is possible to access the virtual machine region 7-2 by deleting the contents of the virtual machine region 7-2. Of course, by setting the contents of the base register to, for example, "D3J," the thin needle calculator 8-1 can be configured as a VM2-3+!: multiprocessor system.

(As explained above, according to the present invention, it is possible to configure a multiprocessor system using any virtual machine (VM)), and the existing AVM control program 5, etc. There is no need to change.
