摘要:
A system for ensuring high reliability in a block service disk array system while promoting high performance by logically writing all changes to strides on the array while physically writing ahead to a log only a subset of the changes. Specifically, for changes of only a strip or so, the changes are written to a log, along with a commit record, and then written to disk, later deleting the changes from the log. In contrast, for relatively larger changes, i.e., for an entire (or nearly entire) stride, the old stride is not overwritten by the new, but rather is written to a new location on the disk, with the new and old locations and a commit record (but not the new stride itself) being logged and with the entries for the locations in the stride mapping table swapped with each other. In an alternate embodiment, blocks can be written to temporary locations in a RAID-1 area and lazily moved to home locations in a RAID-5 area of an array of disks.

A method of writing to cache in a clustered environment. A first node in a storage cluster receives a request to write data from a user application. The first node determines if the data is owned by a remote node. If the data is owned by a remote node, the data in the remote node may be invalidated, if necessary. Such invalidation may not be necessary if a global cache directory is utilized. Thereafter, the data is written in a cache of the first node. Additionally, the data is written in a cache of a partner node of the first node. Confirmation of the cache write in the partner node is then received in the first node.

The present invention provides a method, Web server and computer system for converging a desktop application and a Web application. The method may comprise: in response to a request from a client user for using a target desktop application, starting a desktop application initialization process on the Web server and determining an appropriate corresponding hosting server for the user; preparing and provisioning desktop application environment on the corresponding hosting server and starting the target desktop application; transmitting the corresponding hosting server's address to the client so as to make desktop application interaction between the client and the corresponding hosting server; and in response to the completion of the desktop application interaction, stopping and exiting the target desktop application on the corresponding hosting server.

In general, this disclosure describes techniques for coding video data for random access. In particular, this disclosure proposes to code a syntax element that indicates if a dependent picture may be successfully decoded in the event of a random access request to a clean decoding refresh (CDR) picture and may be required for decoding the pictures following the clean decoding refresh (CDR) picture in display order.
摘要:
Aspects of this disclosure relate to a method of coding video data. In an example, the method includes obtaining, from an encoded bitstream and for any view component of a first view, reference view information indicating one or more reference views for predicting view components of the first view. The method also includes including, for decoding a first view component in an access unit and in the first view, one or more reference candidates in a reference picture list, where the one or more reference candidates comprise view components in the access unit and in the reference views indicated by the reference view information, where the number of reference candidates is equal to the number of reference views. The method also includes decoding the first view component based on the one or more reference candidates in the reference picture list.

Aspects of this disclosure relate to a method of coding video data. In an example, the method includes obtaining, from an encoded bitstream, one or more network abstraction layer (NAL) units for each view component of a plurality of view components of encoded video data, where each view component of the plurality of view components corresponds to a common temporal location, and where the one or more NAL units encapsulate at least a portion of the encoded video data for the respective view components and include information indicative of a decoding order of the respective view components. The method also includes obtaining information, separate from the NAL units, indicating relationships between view identifiers for the views and the decoding order of the view components. The method also includes decoding the encoded video data of the plurality of view components in the decoding order based on the received information.

A DNA library, and a preparing method thereof, a method of determining DNA sequence information, an apparatus and a kit for detecting SNPs, and a method for genotyping may be provided. The method for preparing the DNA library may comprise the steps of: digesting a genomic DNA sample using a restriction endonuclease to obtain a digested product, wherein the restriction endonuclease comprises at least one selected from the group consisting of Mbo II and Tsp 45I; separating the digested product to obtain DNA fragments having a length of 100 bp to 1,000 bp; end-repairing the DNA fragments to obtain an end-repaired DNA fragments; adding a base A to the end of the end-repaired DNA fragments to obtain DNA fragments having a terminal base A; and ligating the DNA fragments having the terminal base A with sequencing adaptors to obtain the DNA library.

Aspects of this disclosure relate to, in an example, a method that includes identifying a first block of video data in a first temporal location from a first view, wherein the first block is associated with a first disparity motion vector. The method also includes determining a motion vector predictor for a second motion vector associated with a second block of video data, wherein the motion vector predictor is based on the first disparity motion vector. When the second motion vector comprises a disparity motion vector, the method includes determining the motion vector predictor comprises scaling the first disparity motion vector to generate a scaled motion vector predictor, wherein scaling the first disparity motion vector comprises applying a scaling factor comprising a view distance of the second disparity motion vector divided by a view distance of the first motion vector to the first disparity motion vector.

A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. The system might include controlling the sequence, timing and construction of block requests, time based indexing, variable block sizing, optimal block partitioning, control of random access point placement, including across multiple presentation versions, dynamically updating presentation data, and/or efficiently presenting live content and time shifting.
