Abstract: A request for determining a unique object identifier for an object located somewhere within a plurality of data processing systems in a network may be received from an application by a single data processing in the network. A local object index containing object attribute records is searched for matches with specified input criteria and any matches are identified. A local search list is then consulted and, if other object indexes require searching, the request is forwarded to the next object index on the list together with an indication of the object index or indexes already searched. The inclusion of an indication of indexes already searched prevents a loop-back condition from occurring. As each object index is searched, the search list is consulted and, if additional object indexes remain to be searched, the request is propagated to the next object index and the results of searching a local object index are returned to an originating data processing system.

Abstract: The present invention is a method and apparatus for retrieving information from a database. Initially, the documents within the database are divided into mutually exclusive subdocuments that generally correspond to paragraphs of text. The present invention further creates a second set of subdocuments that overlap adjacent paragraphs of text. In particular, the location of the overlapping subdocuments depends on the size of the initial paragraphs. This second set of overlapping subdocuments are scored just as the mutually exclusive subdocuments are scored. The scores from both the mutually exclusive and overlapping subdocuments are used in ranking the relevance of documents to a query. The use of both sets of subdocument scores improves the effectiveness of the scoring algorithm.

Abstract: A technique for managing address translation storage buffers (TSBs) supports multiple pools of different TSB sizes and dynamically assigns a process to its own TSB of the proper size as the needs of the process change. A process is assigned a small TSB and the system migrates the process to a larger TSB if needed. One method includes the steps of identifying sizes of TSBs to support, allocating a TSB pool in memory with these sizes, selecting an appropriately sized TSB for a process, and migrating that process to a larger size should the process require more memory. A second method allocates a TSB pool by determining an appropriate size for the TSB pool, determining sizes of TSBs to support, allocating memory for the pool and initializing status block for each size of TSB. A third method selects an appropriate TSB for a process by selecting a smallest supported size of a TSB from the pool.

Abstract: A method is provided for identifying compound terms in a document that is represented by a stream of tokens. The stream of document tokens is scanned for an initial term associated with a compound term and a compound term template is accessed when the initial term is identified. The template includes content, retention, and token specifications for the compound term. The stream of tokens is compared with the template, and when the stream matches the content specification of the template, a token representing the compound term is tagged according to the retention specification and added to the stream of tokens. The tagged token is stopped according to the retention specification represented by its tag.

A computerized system in accordance with the principles of the present invention includes a "bridge" for retrieving data from the non-object-oriented datastore in response to a query request received from an application program and for encapsulating the retrieved data in one or more datastore persistent objects, wherein the query request conforms to a syntax that provides for a qualified retrieval of one or more collections of datastore persistent objects and the datastore persistent objects are materialized as members of one or more of the collections.

Abstract: A system for generating a structured query language query to extract data from a database wherein the database includes a schema defined by a plurality of record sources and a plurality of relationships therebetween. The system includes selecting a field set containing at least one field from among said plurality record sources in said database, and determining a minimal path relationship between each of the plurality of record sources in the database that contain at least one field from the field set. The minimal path relationship includes at least one indirect relationship between two of the plurality of record sources in the database that contain at least one field from the field set. Output from the intelligent joining system is a Structured Query Language (SQL) statement in the syntactical form that a database management system can execute.

Abstract: A parallel computer comprised of a plurality of identical processors, each processor having control and data inputs and outputs for communication with the host computers and separate interprocessor inputs and outputs for communication between the processors. The processors are permanently interconnected through interprocessor communications routers into a first, single n-cube array for purposes of interprocessor communication. The data and control inputs and outputs of the processors are separately connected in parallel to the host computers through a resource allocation means to divide the first, single n-cube array of processors into a multiplicity of smaller second arrays controlled by selected ones of the host computers.

Abstract: The multiplexing character processor of the present invention multiplexes data characters to and from a plurality of communication lines to a Central Processing Unit by bit slicing. Input data present on the plurality of communication lines is sampled at a rate which is at least 16 times the data bit rate and is formulated as a serial data bit stream. Each sample corresponds to a time slice which slice is allocated to a given communication line under the control of a scan list. A high data rate communication line can be placed on the scan list more than once to insure accurate data reproduction. Character assembly and disassembly is performed in an arithmetic logic unit (ALU) under program control, to provide the flexibility to support various communication link protocols. The input data on each communication line may have a different protocol. Synchronization of the serial data bits to the communication lines is performed by a data bit synchronizer DBS.

An interrupt servicing node provides interrupt acknowledge messages including destination data specifying a particular interrupting node at times when the interrupt servicing node is ready to service an interrupt request message. The interrupt servicing node includes storage for specifying the identity of a particular interrupting node and for indicating that an interrupt request is pending from a particular interrupting node. An interrupting node provides to the pended bus an interrupt request message including ID data for identifying the interrupting node as the source of an interrupt request. The interrupting node detects whether an interrupt acknowledge message on the bus includes destination data specifying that interrupting node.
