    摘要: A method for extending the exponent range in an IBM System/370-type floating point arithmetic processor. Very large or very small numbers are represented by a pair of words having sign, exponent, and fraction portions thereof. If the signs of the low- and high-order words of a pair are the same, then the number is deemed to be in the ordinary processor operating range. However, if the signs differ, then the number is deemed to be out of range. In this case, a range extension is obtained by using the exponent field of the low-order word which otherwise would be transparent to the floating point processor.

    摘要: Illustrated is a system and method that includes identifying data stored as an entry in a list. The system and method also includes truncating the entry to create a truncated entry. It further includes transforming the truncated entry into a hash, the hash used to set an index position value within a Bloom filter. The system and method also includes an interface module to transmit the Bloom filter.

    摘要: Various approaches are described for auditing integrity of stored data. In one approach, a data set is provided from a client to a storage provider, and the data set is stored at a first storage arrangement by the storage provider. An auditor determines whether the data set stored at the first storage arrangement is corrupt without reliance on any part of the data set and any derivative of any part of the data set stored by the client. While the auditor is determining whether the data set stored at the first storage arrangement is corrupt, the auditor is prevented from being exposed to information specified by the data set. The auditor outputs data indicative of data corruption in response to determining that the data set stored at the first storage arrangement is corrupt.

    摘要: A storage manager provides data privacy, while preserving the benefits provided by existing hash based storage systems. Each file is assigned a unique identifying code. Hashes of the content-derived chunks of the file are calculated based on the content of the chunk and the code identifying the file. When a request to store a chunk of data is received, it is determined whether a chunk associated with the hash has already been stored. Because hashes are based on privacy-preserving codes as well as content, chunks of duplicate copies of a file need not be stored multiple times, and yet privacy is preserved for content at a file level. In other embodiments, hashes indicating whether a given file is public and/or indicating the identity of the requesting user are also sent with storage requests. These additional hashes enable more robust transmission and storage efficiency, while still preserving privacy.

    摘要: A file sharing system includes authorization-based security to control access to shared files; and a synchronizer which uses the authorization-based security to monitor the shared files for changes and propagating the changes according to sharing relationships. A method for file sharing includes using authorization-based security to control access to a shared file; and monitoring the shared file for changes using a synchronizer which incorporates the authorization-based security to access the shared file.

    摘要: A computer-implemented automated decision support system for designing an auction for a given item includes a structure extractor that estimates unknown elements of market structure of the auction based on auction characteristics data extracted from historical auctions for similar items and a bidding model matching the extracted auction characteristics data. The decision support system also includes a bidding behavior predictor that predicts bidding behaviors of bidders in the auction based on the estimated unknown elements of market structure and characteristics of the auction. In addition, the system includes an optimizer that employs an evaluation criterion to generate an evaluation of the auction based on (1) the estimated unknown elements of market structure and (2) the predicted bidding behavior of bidders. A method of providing an automated auction analysis is also described.

    摘要: A software system with task-specific flexible bindings that enhance the ability to dynamically add and remove resources from availability to tasks and that eliminates the need for coordination of globally unique names. The software system includes a task-specific name space which corresponds to a task executing in the software system. The task-specific name space holds flexible bindings each of which associates a task-specific name used by the task to refer to a desired resource or a set of one or more resources of the computer system and to information that describes the desired resource. The software system includes a resource mediator that obtains a message from the task. The resource mediator keeps information for each resource that identifies a resource handler task for the desired resource by resolving the task-specific name using the flexible binding.
