  • Patent number: 9779041
    Abstract: Embodiments disclose techniques for enabling the use poll and select subroutines with coherent accelerator block or character devices. In one embodiment, an operating system receives, from an application, a system call to attach a hardware context with the coherent accelerator block or character device. The operating system generates a channel based on a file descriptor associated with the attach system call. The operating system associates the channel with a hardware context selected from a plurality of hardware contexts available to the coherent accelerator, wherein the hardware context is attached to the application. Upon receiving, from the application, a system call to check for exceptions that have occurred on the coherent accelerator block device or character device, the operating system returns an indication of any exceptions which have occurred while the coherent accelerator was using the hardware context to the application.

  • Patent number: 8311993
    Abstract: Some embodiments of the inventive subject matter are directed to performing sub-transactions of a long-lived transaction (LLT) in a sequence (e.g., according to an LLT flow) and writing a log entry at the performance of each of the sub-transactions that specifies results of the sub-transaction. Some embodiments do not require generating any compensating transactions during performance of the sub-transactions. Some embodiments are further directed to detecting that an interruption occurs to the LLT and repeating, or initiating re-performance of the LLT from the beginning of the sequence following the flow of the LLT from its beginning. During the re-performance of the LLT, some embodiments are further directed to checking the log entry at each sub-transaction to determine whether the sub-transaction was performed successfully before the interruption.

  • Patent number: 4897781
    Abstract: In a distributed environment several data processing systems are interconnected across a network system. A distributed services program installed on the systems in the network allows the processors to access data files distributed across the various nodes of the network without regard to the location of the data file in the network. The processing system accessing file, referred to as the client processing system, utilizes a client cache within its operating system to store the data file. Utilizing the client cache minimizes the number of reads and writes that must go over the network to the server processing system where the file physically resides. The system and method of this invention prevents a process in the client processing system from accessing data in the client cache that has been modified at another node in the network. The blocks of data in the client cache are tested for validity in the client processing system by using modification times as measured by the server processing system.

  • Patent number: 4887204
    Abstract: A distrbuted services program installed on each of a plurality of data processing systems in a network allows the processors to access data files distrbuted across the various nodes of the network.To reduce the network traffic overhead when files at other nodes are accessed, and to preserve the file system semantics, i.e. the file integrity, the accessing of the various files are managed by file synchronization modes. A file is given a first synchronization mode if a file is open at only one node for either read or write access. A file is given a second synchronization mode if a file is opened for read only access at any node. A file is given a third synchronization mode if the file is open for read access in more than one node, and at least one node has the file open for write access.If a file is in either the first or second synchronization mode, the client node, which is the node accessing the file, uses a client cache within its operating system store the file.

  • Patent number: 4573138
    Abstract: In order to avoid the problem of the last line of the body text not being justified when it is not the end of a paragraph but is followed by a footer, a converter/processor (13) is provided to modify the print data stream produced by another converter/processor (12) from the revisable or editable text data stream. If during conversion from the revisable data stream to the print data stream a "last body text line" is found and it is not the end of a paragraph, a latch (34) is set. Then, with each line of print data stream text, the latch is checked, and if the latch is set and the text line ends with a carriage return, the carriage return is replaced with a zero-index-carriage return and an index. These act similar to a carriage return in all cases except one--the text line which they terminate may now be justified.
