An apparatus and method for making fractional assignments of processing elements to processing nodes for stream-based applications in a distributed computer system includes determining an amount of processing power to give to each processing element. Based on a list of acceptable processing nodes, a determination of fractions of which processing nodes will work on each processing element is made. To update allocations of the amount of processing power and the fractions, the process is repeated.

Method and apparatus for assigning fractional processing nodes to work in a stream-oriented computer system

A method of choosing jobs to run in a stream based distributed computer system includes determining jobs to be run in a distributed stream-oriented system by deciding a priority threshold above which jobs will be accepted, below which jobs will be rejected. Overall importance is maximized relative to the priority threshold based on importance values assigned to all jobs. System constraints are applied to ensure jobs meet set criteria.

A method for dynamically converting electronically encoded HTML document from a text format to an image format. The method includes receiving a request for the content from a client, obtaining the content in text format, determining a content creation preference, and converting the content in text format to content in the image format according to the content creation preference. The method includes replying to the request, wherein the reply includes the content in the image format. The method applies a watermark to the content in the image format according to a watermarking preference. The method generates an image map in accordance with a mapping preference, wherein the image map relates selectable spatial display coordinates to external document identifiers.

Method for generation and assembly of web page content

A method, a system, an apparatus, and a computer program product are presented for a fragment caching methodology. After a message is received at a computing device that contains a cache management unit, a fragment in the message body of the message is cached. Subsequent requests for the fragment at the cache management unit result in a cache hit. A FRAGMENTLINK tag is used to specify the location in a fragment for an included or linked fragment which is to be inserted into the fragment during fragment or page assembly or page rendering. A FRAGMENTLINK tag may include a FOREACH attribute that is interpreted as indicating that the FRAGMENTLINK tag should be replaced with multiple FRAGMENTLINK tags. The FOREACH attribute has an associated parameter that has multiple values that are used in identifying multiple fragments for the multiple FRAGMENTLINK tags.

Method and system for caching message fragments using an expansion attribute in a fragment link tag

A method, a system, an apparatus, and a computer program product are presented for a fragment caching methodology. After a message is received at a computing device, a fragment in the message body is cached. Cache ID rules from an origin server accompany a fragment to describe a method for forming a unique cache ID for the fragment such that dynamic content can be cached away from an origin server. A cache ID may be based on a URI and/or query parameters and/or cookies that are associated with a fragment. After user authentication, a cookie containing the user's role may be used in subsequent requests for role-specific fragments and in the cache identifier for role-specific fragments, thereby allowing requests from other users for role-specific fragments to be resolved in the cache when the users have the same role because these users would also have the same cookie.

Method and system for caching role-specific fragments

A method for managing computer memory, in accordance with the present invention, includes maintaining multiple sets of free blocks of memory wherein a free block is added to a set based on its size. In response to a request for a block of a request size, a set of blocks is searched for a free block which is at least as large as the request size but smaller than the request size plus a threshold. If such a block is found, the block is allocated in its entirety.

System and method for persistent and robust storage allocation

A method, a system, an apparatus, and a computer program product are presented for a fragment caching methodology. Within the request path from a client to a server, a first computing device may attach to a request message a message header that indicates that the first computing device supports fragment processing; a second computing device within the request path processes this request message. When the second computing device receives a response message corresponding to the request message, it can check for a message header directive that indicates that it should cache the response message's fragment only if the response path does not have at least one computing device that supports the processing of fragments; if so, then it forwards the response message without caching its contained fragment.

Method and system for restrictive caching of user-specific fragments limited to a fragment cache closest to a user

A method, a system, an apparatus, and a computer program product are presented for a fragment caching methodology. After a message is received at a computing device that contains a cache management unit, a fragment in the message body of the message is cached. Subsequent requests for the fragment at the cache management unit result in a cache hit. A FRAGMENTLINK tag is used to specify the location in a fragment for an included or linked fragment which is to be inserted into the fragment during fragment or page assembly or page rendering. If a FRAGMENTLINK tag is present within the message body of a message, then the FRAGMENT message header for the message may indicate the presence of the FRAGMENTLINK tag with a directive for the FRAGMENT message header, e.g., using a 'contains-fragment' directive.

Method and system for caching fragments while avoiding parsing of pages that do not contain fragments

A method for preparing rules used for generating text to describe structured data comprises providing a sample of structured data, and providing a text corresponding to the sample of structured data to a pattern matching learning engine, the text comprising at least one value from within the sample of structured data. The method further comprises organizing the text into a hierarchy of syntactic components, and building rules based on the text and the sample of structured data, wherein the rules define an organization of the hierarchy of syntactic components.
