摘要： PROBLEM TO BE SOLVED: To efficiently execute a processing based on the importance of a business as the whole computer system in a computer system having a computer capable of executing a computer resource as a plurality of computer images.
SOLUTION: The computer executes a logical split control program in a computer image according to the priorities of respective logical partitions. The identifier of a logical partition and the priority of the logical partition are reported to the disk subsystem in pair. The disk subsystem performs, to the logical partition, a storage access operation by an input and output instruction from the program executed in the computer image of the logical partition on the basis of the priority reported to the computer. The priority is defined based on the CPU resource allocation to the logical partition and the usage rate of a port to the disk subsystem.

摘要： PROBLEM TO BE SOLVED: To arrange a program area in arbitrary actual addresses and to effectively use a storage device by providing a means which performs arbitrary branching from an address to an arbitrary address on a main storage device by specifying an address of a virtual storage.
SOLUTION: A field storing SCD used for extension address conversion of an instruction address is provided in PSW 101. Here, a storage location may be a control register or ASTE. When a branch instruction is executed, a CPU updates the instruction address field in the PSW 101 to the virtual address of a branch destination and also updates the SCD field in the PSW 101. The value of the SCD field is switched before or after the branch instruction, so branching even to a location arranged in a different section on the actual storage device is possible. As the branch instruction is executed, the value of the SCD field provided in an SGT entry 105 is copied as a value stored in the SCD field in the PSW.

摘要翻译：要解决的问题：通过指定虚拟存储器的地址，通过提供在主存储装置上通过提供从地址到任意地址的任意分支的装置来将程序区域布置在任意实际地址中并有效地使用存储装置。解决方案：在PSW 101中提供存储用于指令地址的扩展地址转换的SCD的字段。这里，存储位置可以是控制寄存器或ASTE。当执行分支指令时，CPU将PSW101中的指令地址字段更新为分支目的地的虚拟地址，并且还更新PSW 101中的SCD字段。在分支之前或之后切换SCD字段的值指令，因此分支甚至可以在布置在实际存储设备上的不同部分中的位置。当执行分支指令时，SGT条目105中提供的SCD字段的值被复制为存储在PSW中的SCD字段中的值。

摘要： PROBLEM TO BE SOLVED: To shorten recovery time at the occurance of abnormality and to reduce user's labor required for the recovery of the abnormality at the time of executing inter-job data succession processing by the use of a pipeline method. SOLUTION: A job execution monitoring part 7 monitors the execution state of each job in data succession processing using the pipeline method, and at the time of detecting the existence of an abnormally ended job, accesses an abnormality correspondence control part 8. The control part 8 judges whether the execution of remaining jobs is to be continued also after the occurance of the abnormality or the remaining jobs are to be abnormally ended in accordance with contents specified at the start of the jobs or contents specified from a user at the occurance of the abnormality. After the end of data succession processing, a job reexecution registering part 10 accessed by a job synchronization control part 5 registers the abnormally ended job in a job information storing file 202 to prepare reexecution only at the time of judging that the job abnormally ended in the processing exists and the automatic reexecution of the abnormally ended job is specified.

摘要： PROBLEM TO BE SOLVED: To perform effective load distribution in a cluster type computer system by performing the distribution of jobs for which cooperation among the jobs is considered. SOLUTION: A job distribution control part 11 obtains the information of the job to be newly executed from a job information storage file 41, and when the job specifies an inter-job cooperative function, obtains the values of the loads of respective computers from a load recording table 12 further, obtains the information of the job while executing the inter-job cooperative function from a check table 13, obtains a threshold value determined beforehand from a threshold value table 14 and requests the execution of the job to either job execution part 22 or 32 based on the information. The job execution part 22 or 32 which receives a request obtains the information of the job from the job information storage file and executes it within the present computer. Load information obtaining parts 21 and 31 store the load information of the present computers in the load recording table 12 with a constant interval.

摘要： PROBLEM TO BE SOLVED: To execute a conventional program and to maintain the transferability of the program by checking whether the size of a loaded real address is larger than that of a virtual address by comparison and making an interrupt occur. SOLUTION: An addition circuit 10 adds a base register number 560 designated by the 2nd operand of an instruction 100 requiring a real address, an index register number 570 and displacement 580 to calculate a virtual address 600 of a 31-bit size. A real address of a 31-bit size in a section is calculated by combining a page number 930 and a displacement field 630 of the address 600. A real address expansion mode flag 202 is compared with a section identifier 920. When the flag 202 is off and also, the identifier 920 is not zero, a program interrupt is made to occur, a
