Abstract: An improved mechanism for tracking the execution progress of a task is disclosed. In one implementation, the execution progress of a parent task and one or more child tasks is monitored. The parent task spawns the one or more child tasks, and the child tasks execute concurrently with the parent task. In addition to monitoring the execution progress of the tasks, an overall execution progress value is determined for the parent task. In one implementation, the overall execution progress value is determined based, at least partially, upon the execution progress of the parent task and the execution progress of at least one of the child tasks. By taking the execution progress of the child tasks into account, the overall execution progress value reflects not just the progress made by the parent task itself but also the progress made by the child tasks that it spawned.

Abstract: Efficient development of conventional web applications suggests extensive and thorough knowledge of web page delivery technologies such as HTML, Java, and JSPs. A rendering framework to define the static, cosmetic, “window dressing” type of content, replicated across multiple pages, in a single JSP template file which can then incorporate or include the dynamic, active content from other files, mitigates development inefficiencies. Such a rendering framework represents each screen output page by a file including the active content, while avoiding replication of the static content. Such inclusions may be nested in a hierarchical manner to enumerate the static content in one file and allow a web application to include active content according to a hierarchical inheritance. Metadata components, such as XML files, include the active content according to a predetermined declarative syntax, thereby facilitating implementation, which the framework then interprets into a resulting output page such as a JSP page.

Abstract: Systems and methods are described for providing queue pair numbers for a queue pair to more effectively track and manage the frequency of use and re-use of queue pair numbers on a queue pair context basis in an InfiniBand™ device. The present invention uses a counter for each queue pair context to set the changeable portion of the queue pair number. A reference count for each queue pair context is also used to track the quantity of queue pair numbers currently allocated to a queue pair context. The present invention sets, tracks and manages the values of the counter and the reference count for each queue pair context in conjunction with queue pair operations to provide a systematic queue pair numbering scheme. By tracking and/or setting values of the counter and reference count for a queue pair context, the present invention re-uses queue pair numbers efficiently and in a predictable and repeatable manner.

Abstract: A system that facilitates distinguishing between soft errors and the onset of hardware degradation in a computer system. During operation, the system receives notifications of correctable-error events from a plurality of memory components. The system then averages numbers of correctable-error events from the plurality of memory components to generate an average number of correctable-error events across the plurality of memory components. The system subtracts the number of correctable-error events for a given memory component in a given time interval from the average number of correctable-error events to generate a residual number of correctable-error events for the given memory component in the given time interval.

Abstract: The present invention is directed toward dynamic downloading of keyboard keycode data to a networked client. According to one or more embodiments of the present invention, a user logs into a networked client by presenting a smart card to a card reader attached to the client (or by some other authentication mechanism) and enters a PIN into the keyboard. The keycodes entered by the user logging into the client are obtained, translated into ASCII characters, and presented to the smart card. If the PIN is correct, the user is able to log in, otherwise the log in fails. In one embodiment, when the user enters the PIN, a translation table is downloaded from the server into the client. The client uses the translation table to convert the keycodes to ASCII text and presents the ASCII text to the smart card for authentication.

Abstract: A method and mechanism of enforcing community access control in a computer network, wherein access to objects by users and processes is controlled. A Multi-Community Node (MCN) processes information for users in multiple communities and must enforce a community separation policy. The enforcement method and mechanism use a database of associations of sets of communities corresponding to users, processes, and system objects. Upon receiving a request for access to an object by a user, the MCN permits access if a user community set (UCS) of the user is a superset of an object community set (OCS) of the object; otherwise, access is denied. Upon receiving a request for access to an object by a process, the MCN permits access if an application process community set (ACS) of the process is a superset the OCS of the object; otherwise, access is denied.

Abstract: Methods, systems, and articles of manufacture provide a single multi-language source code file and effects single-language executable files from the multi-language source code file. A program extracts text elements in the first language from the source code. The extracted text elements include context information that identifies a location of the text element in the first language in the source code. Translations of the extracted text elements in a second language are obtained. The translations of the text elements in the second language are merged into the source code at merge locations based on the context information. Versions of the source code in the first language and the second language are then generated.

Abstract: Embodiments of the present invention are directed to a method and apparatus for integration of URL's into standard file systems of a local computer. In one embodiment of the present invention, the file system (e.g., a Uniform File System (UFS)) of a local computer is integrated with an Internet protocol, such as the Hyper Text Transport Protocol (HTTP). Once the protocol has been integrated into the file system of the local computer, applications running on local computer can access any Web based documents under that protocol. Thus, the local applications (and/or users) can access these Web based documents (and/or files) as if they are local files even though the documents are actually located on the Internet (and away from the local computer). In a further embodiment, the applications (and/or users) are able to access these Web based documents by utilizing a relating apparatus that relates the applications (and/or users) to their corresponding Web based documents.

Abstract: One embodiment of the present invention provides a system that buffers data inside of a byte-stream protocol at a transport layer on a client, which is receiving the data from an external source. The system operates by receiving a configuration parameter at the transport layer from an application executing on the client, wherein the configuration parameter specifies a condition upon which data buffered at the transport layer is to be sent to the application. The system then buffers data destined for the application at the transport layer on the client, and sends the buffered data to the application when the condition specified by the configuration parameter is met. Buffering data at the transport layer on the client facilitates more efficient processing of system calls.
