摘要： A unique naming system and method are described for managing object identification by a network of computer systems. The naming system employs data structures stored in the memory of the computer systems containing character strings and corresponding addresses to entries in the data structures and objects in the computer systems. Names employed in a particular computer system that correspond to objects in another computer system are resolved by a border data structure capable of transforming names, delimiters and visas across computer systems.

摘要： An operating system in a digital computer environment is run as a virtual machine on a virtual resource manager. In order to provide a more dynamic environment for the operating system, linkages are made between the operating system device drivers and the corresponding real and virtual devices of the virtual resource manager. This is accomplished by assigning a "token" to the virtual resource manager. A device dependent information file corresponding to the device is created. This file contains adapter dependent information including a hardward port address for the physical device. The "token" is placed in the operating system device driver at the time it is initiated. When the operating system device driver is "opened" to drive the device, it uses the "token" to communicate with the virtual resource manager device driver thereby accomplishing driver to driver binding. This causes the virtual resource manager device driver to use the adapter dependent information in the special file corresponding to the "token" and placed in the process stack.
摘要翻译：数字计算机环境中的操作系统作为虚拟机在虚拟资源管理器上运行。为了为操作系统提供更动态的环境，在操作系统设备驱动器和虚拟资源管理器的对应的实际和虚拟设备之间进行联动。这是通过向虚拟资源管理器分配“令牌”来实现的。创建与设备相对应的与设备相关的信息文件。此文件包含适配器相关信息，包括物理设备的硬式端口地址。 “令牌”在启动时被放置在操作系统设备驱动程序中。当操作系统设备驱动程序“打开”来驱动设备时，它使用“令牌”与虚拟资源管理器设备驱动程序通信，从而实现驱动程序到驱动程序绑定。这导致虚拟资源管理器设备驱动程序在与“令牌”对应的特殊文件中使用适配器相关信息，并将其放置在进程堆栈中。

摘要： A system and method for controlling access to shared resources in a distributed computer system. Access to shared resources is controlled by a local authorization token manager. Only computer processes holding authorization tokens for the requested operation may perform that operation. Each requested operation checks for the proper token. If the token is not held by the process, it is requested. The local token manager resolves token conflicts before granting tokens. A token manager of a distributed file system export protocol also is able to request authorization tokens from the local token manager. The export protocol token manager controls authorization tokens for that particular distributed file system protocol. Multiple different export protocols may request tokens from the local token manager. The shared resources may therefore be shared by multiple different export protocols without conflict. Local processes and processes requesting shared resource operations through an export protocol that does not itself manage tokens are granted tokens through the operation token request mechanism. This mechanism enables local processes to use shared resources without the performance penalty of having to request through a local distributed client process.
摘要翻译：一种用于控制对分布式计算机系统中的共享资源的访问的系统和方法。共享资源的访问由本地授权令牌管理器控制。只有持有所请求操作的授权令牌的计算机进程可以执行该操作。每个请求的操作检查正确的令牌。如果令牌不由进程持有，则被请求。本地令牌管理器在授予令牌之前解决了令牌冲突。分布式文件系统导出协议的令牌管理器还能够从本地令牌管理器请求授权令牌。导出协议令牌管理器控制该特定分布式文件系统协议的授权令牌。多个不同的导出协议可以从本地令牌管理器请求令牌。因此，共享资源可以由多个不同的导出协议共享而没有冲突。通过本身管理令牌的导出协议来请求共享资源操作的本地进程和进程通过操作令牌请求机制被授予令牌。此机制使本地进程能够使用共享资源，而不会因为本地分布式客户端进程请求而导致性能损失。

摘要： Two polygon fill algorithms are presented for filling polygons on a graphics display. The first polygon fill algorithm fills polygons that are strictly convex. The second polygon fill algorithm fills a larger class of polygons than the first polygon fill algorithm which includes polygons being concave in the x direction, and polygons having crossing lines. The first polygon fill algorithm tests the polygon for strict convexity by testing for a consistent turning direction, and by testing for once around in the y direction. The first polygon fill algorithm then stores the maximum and minimum value of the pel selected by the Bresenham algorithm for each scan line of the polygon. The fill line is drawn from the pel having the minimum value to the pel having the maximum value for each scan line of the polygon. The second polygon fill algorithm tests the polygon to ensure that it can be filled with one unique fill line for each scan line of the polygon. The second polygon fill algorithm stores both a minimum value and maximum value for each scan line line of the polygon for each line of the polygon. A fill line is then drawn from the least minimum value to the greatest maximum value for each scan line of the polygon.

摘要： In a distributed data processing system, the authentication of a process at one node for the use of a service at another node is performed in a facility that is separate from the requestor and service process. The separate facility is also replaceable, thereby allowing different authentication policies to be implemented within the distributed data processing system. The requesting process and the service process merely pass the authentication information between themselves without attempting to interpret the work of the separate authentication facility. In addition to authenticating the requestor to the service, the service is also authenticated to the requestor.

摘要： These master system files define the system characteristics that a user at any node in the system can expect to have. The master system files are mounted remotely from each of the nodes of the system and a local copy of the master system files is kept locally reflecting the current contents of the master system file. If a master system file is not available, the local copy is used in read only mode until the node containing the master is available. In addition, each user has its own file tree organization that dictates the necessary remote mounts of directories to enable a user logged on to any node to have the same view of the system that would be obtained from any other node in the system by that user.

摘要： In a computer system with a screen display on which is formed a plurality of at least partially overlapping windows associated with different applications, a depth buffer is added to the display adapter for providing with different applications, a depth buffer is added to the display adapter for providing clipping assistance to the software-based window manager. A refresh buffer stores pixel data for each pixel of the display. The window manager monitors the current depth position of each of the pixels within the display and generates a depth value for each pixel. In response to an input request for window rearrangement, the window manager assigns a new depth value to each pixel in a window affected by the request, requests that each application affected by the rearrangement to retransmit pixel values for the pixels associated with at least the portion of a affected window which will become visible as a result of the rearrangement, and transmits new depth values for at least the pixels within the affected portions of such windows. The depth buffer receives and compares the new depth values with the current depth value for each pixel. If the comparator determines that the new pixel value has a depth value associated with the same window or a window closer to the viewer, the depth buffer notifies the refresh buffer to store the new pixel values for each of the applications affected by the rearrangement.
