摘要： A region comprising a plurality of real pages in a part of a real storage unit is provided with a first key storage unit having a plurality of key storage entries each corresponding to one of the plurality of real pages, while a second region comprising a plurality of real pages in the second part of the real storage unit is provided with a second key storage unit having a single key storage entry. When a real address designated by an instruction to be executed belongs to the first region, an entry corresponding to this address is accessed by a storage protection control circuit. When this address belongs to the second region, the second key storage unit is accessed irrespective of the address. Further, a key within the accessed key information is compared with a key on a program status word (PSW) allocated to a program to determine whether the execution of the instruction is permitted.

摘要： To transfer a file comprising block data at high speed between sequential access type auxiliary memories, a file transmission program inquires of an operating system about the physical storage positions of the block data, determines a reading order to reduce the read access time on the basis of the results of inquiry, and issues read requests sequentially to the operating system according to the reading order. The file transmission program requests the operating system to transmit the read block data. The block data together with respective logical identification data, for example, logical block numbers, are transmitted to a receiving end which may be another computing system. The operating system at the receiving end is requested to secure the number of physical data blocks required to store the block data. The write order of the block data to the physical data blocks is then determined to reduce the access time and the block data are respectively stored in the secured physical data blocks according to the write order. Sequentially, a pair of the logical identifiers of each block data actually written to the data area and physical identification data of the data blocks are stored in the data area.

摘要： A process for partially swapping real storage areas used by a program is utilized in a computer system which executes programs by multiprogramming under control of a virtual storage type operating system. A first portion of a real storage area, allocated to a program to be swapped out, remains allocated to that program while the contents of a second portion of the real storage area are saved in an auxiliary storage so that the second portion is deallocated from that program. The saved contents of the second portion stored in the auxiliary storage are loaded in the real storage when the program is to be swapped in.

摘要： A data processor which specifies either of a predetermined maximum length of an adddress (a bits) and a length of an address less than the former length and at plural registers having a number of length of bits (r bits) of the maximum address length or greater. The data processor reads out lower-order d bits for data or r bits for an address of the one of the plural registers (7) specified by a first instruction to perform an arithmetic or logic operation, and writes the result into one of the plural registers. Moreover, the processor reads out bits having specified length of an address from the one of the plural registers specified in a second instruction to generate an a-bit address, and reads out d for data or r bits for an address from a main storage device (5) in response to the thus-generated address to write the d or r bits into one of the plural registers. Since the data length is consistently d bits irrespective of specified effective length of an address, direct data transfer is enabled between programs each having a different effective length of an address thereby facilitating extension of the length of a storage address and assuring compatibility with conventional data processors.

摘要： A method for allocating real pages larger than a conventional size to a plurality of virtual pages of the conventional size in a system including a real storage containing a plurality of real pages and a storage key for holding storage keys used for storage protection purposes of the real pages. The method includes the steps of (A) allocating one of plural split regions having the conventional size obtained by subdividing one of a plurality of real pages having a larger size equal to a value n being a positive integer larger than 1) times larger than the conventional size, to one virtual page having the conventional size (B) repeating step (A) so that split regions having the conventional size within the one real page and within other real pages having the larger size are allocated to virtual pages having the conventional size. Either a real page of a larger size or a group of consecutively located split regions of the convention size are allocated to a virtual page of a size larger than the conventional size.

摘要： Logical blocks are allocated to a plurality of logically sequential blocks of data by referring to disc array configuration information and a list of candidate logical blocks that may be allocated, so that the drives for retaining the logical blocks assigned to the blocks of data and the drives for holding the parities for these logical blocks will be all different. Thus, a total number of drives which operate in parallel for executing sequential writes to the disc array can be increased to a maximum extent.

摘要： In order to perform format conversion between the formats of a plurality of files without any work by a user, a file system stores a relation between a conversion originating file and a conversion destination file, and synchronously with an issue of a file operation API, the format conversion processes are executed. A user performs only the tasks essential for an application, without taking into consideration various necessary format conversions (either one-step or multi-step). During the user task, it is not necessary to designate a conversion originating file and a timing of format conversion. A user can use always a latest conversion destination file.

摘要： In correspondence to an application, a resource table to manage computing resources which are available for the application is provided in a rule such that a plurality of applications can mutually use distributed computing resources which could be used so far by itself and can effectively use many distributed computing resources and an execution performance can be raised. When a certain application executes a cooperative processing together with another application, resource tables are copied and a new resource table for managing resources of both of them is formed. By referring to a newly formed resource table by each application, each application can use both of the computing resources more efficiently.
