Abstract: A computer system having a chief system control program (CHIEF SCP) running in a real machine as a host where the host controls standard system control programs (SCP's)(SCP(1), SCP(n)) and controls virtual machines (Domains) called guests (GUEST (a), GUEST (p)). Guests operate with interpretive execution as second-level guests. Control is transferred from a second-level guest to the guest SCP or to the chief SCP with only one control interception. Control is transferred directly between the second-level guest and Chief SCP bypassing the first-level guest.

Abstract: A computer system that has means for processing (266) interrupt requests that are generated both by hardware interrupt request generators (260..., 265) and by control software (264). A common register array is provided having locations for the general registers and the control registers and having specifically interrupt register locations (261) for storing interrupt requests. The hardware generators (260..., 265) store the interrupt requests into the interrupt register locations (261). Similarly, the control software (264) reads and writes to the interrupt register locations (261) whereby interrupt requests can be generated and terminated in a unified manner under software and hardware control.

Abstract translation: 一种计算机系统，具有用于处理（266）中断请求的装置，所述中断请求由硬件中断请求生成器（260 ...，265）和控制软件（264）生成。 提供了一个公共寄存器阵列，其具有用于通用寄存器和控制寄存器的位置，并且具有专门用于存储中断请求的中断寄存器位置（261）。 硬件发生器（260 ... 265）将中断请求存储到中断寄存器位置（261）中。 类似地，控制软件（264）读取和写入中断寄存器位置（261），由此可以在软件和硬件控制下以统一的方式产生和终止中断请求。

Abstract: A file system for managing data files for access by a plurality of users of a data processing system that includes internal storage (41) for buffering, external storage (44), and a file user interface (I) by which the plurality of users request access to data files. A first level, coupled to the file user interface (41) for temporary storage of data to be accessed by the plurality of users, and generates requests for transactions with external storage (44) in support of such allocations. A second level is coupled to the first level and the external storage (44) and responds to the request for transactions with the external storage (44) for managing the transactions for storage of data to, and retrieval of data from, the external storage (44).

Abstract: To perform a sort of N records, a two-dimensional tree structure is formed with a tree of subtrees, where each subtree is formed by a plurality of nodes organized in a binary tree. For each leaf node in the tree, there is an ancestor chain of nodes (from child to parent, from parent to grand-parent, from grand-parent to great-grand-parent, ... and so on) that connects each leaf node to the root node. To perform the sort, the processing unit stores codes representing keys into nodes in the two-dimensional tree and performs a tree sort of the keys using the codes. The codes are accessed in the subtrees and processed to determine the sort order of the keys and therefore the sort order of the corresponding records. The size of the subtrees is adapted to the size of the cache.

Abstract translation: 为了执行一种N个记录，使用一棵子树形成二维树结构，其中每个子树由组织在二叉树中的多个节点形成。 对于树中的每个叶节点，连接每个叶子的节点（从小孩到父母，从父母到祖父，从祖父到祖父，等等）的祖先链 节点到根节点。 为了执行排序，处理单元将代表密钥的代码存储在二维树中的节点中，并使用代码执行树的分类。 代码在子树中进行访问，并进行处理以确定密钥的排序顺序，因此确定相应记录的排序顺序。 子树的大小适应高速缓存的大小。

Abstract: A distributed computing system (6) having a distributed protocol stack (12). In a system including one or more general purpose computers or other application processors (8) for running applications (22), the distributed protocol stack (12) off-loads communication or other I/O processing from the application processor (8) to dedicated I/O processors (9) using a STREAMS environment thereby enhancing the performance/capacity of the system. The distributed protocol stack (12) is formed of a STREAMS stack top (15) and a stack bottom (16) so that together the stack top (15) and stack bottom (16) comprise a full stack (12) functionally equivalent to a non-distributed stack running on an application processor (8). Both the application processors (8) and the I/O processors (9) together appear to execute the full protocol stack (12), but the application processor (8) only executes the stack top (15) while the I/O processor only executes the stack bottom (16).

Abstract: A set of scan latches (SL) is partitioned into unique groups (243a, b, c) where each group is addressable by a group initializing circuit (350, 360). The group initializing circuit initializes all the latches of an addressed group to a predefined state thereby quickly loading a test vector into the addressed group of scan latches while leaving other latches undisturbed.

Abstract: A system for program development and execution consisting of a high level programming language based on a four part rule organization (31), consisting of a rule definition, a list of conditions, a list of actions taken upon satisfaction of a corresponding condition, and a list of exception handlers. Data access events are supplied through a table access method (21) which provides an interface to the variety of sources of data (22-30) coupled to the system. A table data store (103) organizes data in an object oriented, relational system, where each table is ordered on a primary key (502). The table access method (21) performs selection and ordering operations on the tables accessible through the table access method (21), implements and triggers invalidation routines upon data access events, and provides a common view of data stored across heterogeneous data stores coupled through servers (203-205) to the table access method (21). Ordered tables (103) are subdividable by additional parameters associated with table names.
