摘要： Provides load balancing, recovery and reconfiguration control for a data move subsystem comprised of a plurality of interconnected and cooperating data move processors (DMPs). Each DMP processor has an associated queue for receiving queue elements (QEs) from central processing units of a data processing system which specify data move requirements of the data processing system. QEs can be transferred between queues of other DMPs or a common queue to achieve load balancing, recovery and reconfiguration control.

摘要： A control process which enables a non-supervisory "using program" (e.g. application programs) to directly interface one or more shared asynchronous hardware facilities in a computer system. Any using program may request the operating system (OS) to set up a "special environment" with an AHF during which the using program can directly issue requests to the AHF for its services. The OS sets up a session for the using program having the "special environment", which specifies restrictions on storage accesses by the AHF for accesses made on behalf of the using program--to insure system data integrity. These restrictions are not changeable by the using program. The "special environment" exists until the session is ended by the using program or by a terminating condition. The "special environment" is tailored to be different among the different using program concurrently using the same AHF, so that the "special environment" of one using program cannot interfere with the "special environment" of another using program. During a session, work requests for any using program are communicated directly to the AHF from the using program, and completion of any work request is communicated directly by the AHF to the using program without any interruption of the using program or OS involvement.
摘要翻译：能够使非监督“使用程序”（例如应用程序）直接接入计算机系统中的一个或多个共享异步硬件设施的控制过程。任何使用程序可以请求操作系统（OS）与AHF建立“特殊环境”，在此期间，使用程序可以直接向AHF发送其服务请求。操作系统为具有“特殊环境”的使用程序设置会话，该特定环境指定AHF对代表使用程序进行访问的存储访问的限制，以确保系统数据完整性。使用程序不能更改这些限制。存在“特殊环境”，直到会话由使用程序或终止条件结束。 “特殊环境”在不同的使用程序中使用相同的AHF进行了不同的定制，使得一个使用程序的“特殊环境”不能干扰另一个使用程序的“特殊环境”。在会议期间，任何使用程序的工作请求都从使用程序直接发送到AHF，AHF直接将任务完成任务发送到使用程序，而不会中断使用程序或操作系统的参与。

摘要： Provides a software-to-software interface and a software-to-hardware interface between software users and a hardware ADM facility (ADMF) in a data processing system. Such software user presents only virtual addresses to the software-to-software interface in a MSB list. The user list defines virtual address spaces, including a "hiperspace", in a manner that represents physical backing media as different random-access electronic storages, such main storage (MS) and expanded storage (ES). The real data transfers are within or between the backing storages. The user list is transformed into an ADM operation block (AOB), which is assigned an ADM UCB in a UCB queue which is associated with an ADM subchannel. The software-to-hardware interface generates an ORB, containing the AOB address, as an operand of a SSCB instruction which is executed to queue the associated subchannel onto one of plural co-processor queues in the ADMF. The ADMF uses the AOB to perform the requested page moves, and generates an interruption upon completion of each request which is sent to the hardware-to-software interface to remove the associated ADMF request from the ADM software request queue and free the associated ADM UCB for use by another user request.

摘要： Virtual addressing is available to a co-processor to asynchronously control the movement of multiple page units of data between different locations in the same or a different media, e.g. main store (MS) and expanded store (ES), or both may be in ES, or both may be in MS. The co-processor controls the asynchronous page movement in parallel with continuing execution of other instructions by the central processor (CP) which requested the page movement. Each page to be moved is specified by an MSB (Move Specification Block). A set of MSBs are addressed by a special type of channel control word (CCW) in a channel program containing one or more CCWs, some of which may address one or more sets of MSBs (one MSB set per CCW) to control the movement of any number of pages. The CPU executes a special ADM SSCH (start subchannel) instruction that passes the page move work to the co-processor to perform the requested page transfer involving one or more sets of MSBs. Flag fields in source and sink specifications in each MSB contains a plurality of flag bits that define: the associated source or sink media, whether the specified address is to be translated as a virtual address or to be handled as an absolute address, whether replication of the source page(s) is to be done at the sink location, and whether the page(s) are to be erased by only accessing the sink pages to control the writing of a predetermined padding character, such as zero, through-out the content of the sink page(s).
摘要翻译：虚拟寻址可用于协处理器以异步地控制在相同或不同介质中的不同位置之间的多页数据单元的移动，例如，主存储（MS）和扩展存储（ES），或两者可以在ES中，或者两者都可以是MS。协处理器通过请求页面移动的中央处理器（CP）继续执行其他指令来并行控制异步页面移动。要移动的每个页面由MSB（移动规范块）指定。一组MSB由包含一个或多个CCW的信道节目中的特殊类型的信道控制字（CCW）寻址，其中一些可以寻址一个或多个MSB集合（每个CCW设置一个MSB）以控制移动任意数量的页面。 CPU执行特殊的ADM SSCH（启动子信道）指令，该指令将页面移动工作传递给协处理器，以执行涉及一个或多个MSB集合的所请求的页面传送。每个MSB中的源和接收器规范中的标志字段包含多个标志位，其定义：相关联的源或宿介质，指定的地址是否被转换为虚拟地址或被作为绝对地址处理，是否复制源页面将在接收器位置完成，并且通过仅访问接收器页面来擦除页面，以控制写入预定的填充字符，例如零，通过内容页面的内容。

摘要： In a communications channel coupled to multiple duplicated subsystems, a method, interposer and program product are provided for verifying integrity of subsystem responses. Within the communications channel, a first checksum is calculated with receipt of a first response from a first subsystem responsive to a common request, and a second checksum is calculated for a second response of a second subsystem received responsive to the common request. The first checksum and the second checksum are compared, and if matching, only one of the first response and the second response is forwarded from the communications channel as the response to the common request, with the other of the first response and the second response being discarded by the communications channel.

摘要： A method is described for implementing a trusted computing environment within a data processing system where the data processing system includes a single hardware trusted platform module (TPM). Multiple logical partitions are provided in the data processing system. A unique context is generated for each one of the logical partitions. When one of the logical partitions requires access to the hardware TPM, that partition's context is required to be stored in the hardware TPM. The hardware TPM includes a finite number of storage locations, called context slots, for storing contexts. Each context slot can store one partition's context. Each one of the partitions is associated with one of the limited number of context storage slots in the hardware TPM. At least one of the context slots is simultaneously associated with more than one of the logical partitions. Contexts are swapped into and out of the hardware TPM during runtime of the data processing system so that when ones of the partitions require access to the hardware TPM, their required contexts are currently stored in the hardware TPM.

摘要： Connects a host computer system (such as a mainframe or host server system) to a large multimedia (MM) distribution network having wide scalability without being limited by bandwidth constraints in the host system or in any multimedia controller for controlling "on demand" viewing of movies at a large number of set-top-boxes (STBs) with TV sets. Connected to the host system is a network distribution arrangement comprised of a plurality of multimedia (MM) adapters, each MM adapter containing a plurality of MM controllers, each MM controller being connected to a multiplicity of MM pairs, each MM pair being connected to the network for controlling a direct distribution of movies to a large number of STBs. Each MM pair includes a disk adapter and a network adapter connected by a common MM pair bus for transmitting disk data blocks directly to the STBs. The disk adapter controls and receives data from one or more disk devices. The network adapter sends the disk data to the network. In each MM pair, a pair bus connects the network adapter to transmit data from the disk adapter to the network. Data files (movies) are stored on the disks, and any file can be selected by an STB for transmission to the STB. Data blocks are read directly from the disk to the pair bus and then directly through the network to the requesting STB. Any STB may issue interactive commands to control a data file while it is being received.
