摘要： The present invention relates to a computer system having a disk cache unit between a disk unit and the main storage unit. Ordinarily, the data transfer processing is carried out between the disk unit and the disk cache unit and between the disk cache unit and the main storage unit in this case under control of a director. The present invention is characterized by enabling these two data transfer operations to be executed in parallel and to prevent the director from becoming the bottleneck of the processing due to the concentrated processing requests. For this purpose, the present invention provides for a data transfer between the disk cache unit and a disk unit while a data transfer is taking place between the main storage unit and the disk cache unit.
摘要翻译：本发明涉及一种在盘单元和主存储单元之间具有盘缓存单元的计算机系统。通常，在这种情况下，在导向器的控制下，在盘单元和盘高速缓存单元之间以及盘缓存单元和主存储单元之间执行数据传送处理。本发明的特征在于能够并行地执行这两个数据传送操作，并且防止由于集中的处理请求引导器成为处理的瓶颈。为此，本发明提供了在主存储单元和盘高速缓存单元之间进行数据传输的同时在盘缓存单元和盘单元之间的数据传送。

摘要： An input/output control system has a control unit including a first controller connected between a channel and a data buffer for controlling the transfer of data therebetween and a second controller connected between the data buffer and a plurality of input/output devices for controlling the transfer of data therebetween. A start action of the input/output device is effected in an off-line mode from the control unit. The amount of data stored in the data buffer is checked each time the transfer of data occurs between the channel and the data buffer. In the case of a read processing, when the amount of data stored in the data buffer becomes less than a first predetermined value, data is transferred for preload from the input/output devices to the data buffer. In the case of a write processing, when the amount of data stored in the data buffer exceeds a second predetermined value, data is transferred for after-write from the data buffer to the input/output devices. Each of the first and second predetermined values is determined depending on the amount of input/output devices which are in an active state at that time. When each of the active input/output devices is allocated with m (.gtoreq.2) unit fields of the data buffer each of which has a capacity of K/(mn) where K is the whole capacity of the data buffer and n is the number of the active input/output devices, the first and second predetermined values may be K/(mn) respectively.

摘要： An autonomous resource management method for improving performance of a system in which plurality of process units compete for resources. Previously determined allocation policies are stored in memory along with system status data, control data and an evalution of the effectiveness of the allocation policy. During the operation of the system, the status is detected and an allocation policy is retrieved from memory based on the detected status. The allocation policy is then modified and sent to the scheduler. The effect of modifying the allocation policy is detected and an evaluation of the modified allocation policy is stored in memory. Inferior allocation policies are deleted from memory.
