    • A distributed shared memory management system for a distributed shared memory computer system having a plurality of computers interconnected by a network, each computer having an independent address space and logically sharing data physically distributed to a storage of each computer. Each computer running a program for reading/changing the shared data includes a coherence control designation command for designating to enter a mutual exclusion state in which two or more computers cannot change the logically single shared data, a coherence control release command for designating a release of the mutual exclusion state, and a coherence control execution command for reflecting the contents of the shared data changed between the coherence control designation command and the coherence control release command, upon the logically single shared data in another computer. At least one of the plurality of computers includes a request message queue for storing a coherence control request message issued by the coherence control execution command when the coherence control designation command is executed. The coherence control designation command includes data for designating the order of reading/changing the shared data, and the request message queue includes a counter for storing a current state regarding the control of the order of reading/changing the shared data and a unit for storing a value regarding the control of the order of reading/changing the shared data.

    • A control method of controlling a computer for controlling a resource connected to the computer and shared by a plurality of programs included in the computer includes the steps of storing a control information ID indicating a storage area in the main memory storing control information concerning access between a certain program and the resource in an OS space of a main memory, storing the control information ID in an adaptor connected to the main memory via a bus, and taking out the control information from the storage area included in the OS space, by using the control information ID stored in the adapter. In the case where the adapter runs short of a storage area, information that the adapter runs short of a storage area in the main memory is conveyed via the bus. By using the control information thus taken out, the resource is controlled.

    • A memory disc sharing method in which a plurality of computers share a memory disc through a network, wherein a command in accordance with which the memory disc is accessed is received by a network interface apparatus, and when a requested computer to which a request of the command has been made is any of other computers, the command is transmitted to the any of other computers, and when the requested computer is a computer concerned, the command is stored in a memory disc command queue. The network interface apparatus retrieves the command from the memory disc command queue, and executes the processing of reading out/writing data from/to the memory disc in the computer concerned when a requesting computer from which a request of the command has been made is the computer concerned, and carries out the data transfer between the memory disc in the computer concerned and the requesting computer when the requesting computer is any of other computers.

    • A system for controlling the DMA transfer for a plurality of IO devices has an IO controller for each group of the IO devices. Data is retrieved from memory and stored in the IO controller where it is analyzed. The retrieved data has a structure that permits a group of DMA start request quads to be linked together for parallel or pipeline processing of the DMA transfer requests. Each start request quad has a pointer for additionally retrieving corresponding command data. The command data is set forth in a number of blocks, each linked to the next one by a pointer. When a DMA processing has been completed, the termination or completion status is entered into a specific entry in a completion list for the corresponding IO device. Thus, a determination can be made as to whether specific IO devices have completed a requested DMA processing. Expansion of the system is accomplished by using combinations of main and sub controllers, where one main controller provides the aforementioned data structures for many sub controllers in order to enable the DMA processing to be performed for IO devices connected to the sub controllers with less frequent access of system main memory and the system bus.
    • 用于控制多个IO设备的DMA传输的系统具有用于每组IO设备的IO控制器。 数据从存储器检索并存储在IO控制器中进行分析。 检索的数据具有允许一组DMA启动请求四元组链接在一起以用于DMA传送请求的并行或流水线处理的结构。 每个启动请求四元组都有一个指针,用于附加地检索相应的命令数据。 命令数据在多个块中设置,每个块通过指针链接到下一个块。 当DMA处理完成时,终止或完成状态将被输入到对应的IO设备的完成列表中的特定条目中。 因此,可以确定特定的IO设备是否已经完成了所请求的DMA处理。 通过使用主控制器和副控制器的组合来实现系统的扩展,其中一个主控制器为许多子控制器提供上述数据结构,以便能够对连接到具有较少频率访问的子控制器的IO设备执行DMA处理 的系统主存和系统总线。
