Abstract: Transform coefficients for blocks of pixels in an original picture are quantized to produce respective sets of quantization indices for the blocks of pixels. The quantization indices for at least some of the blocks are produced by using a quantization step size that is not uniform within each block. Largest magnitude quantization indices are selected from the respective sets of quantization indices for (run, level) encoding to produce the (run, level) encoded picture. For example, MPEG-2 coded video includes a set of non-zero AC discrete cosine transform (DCT) coefficients for 8×8 blocks of pixels. For scaling the MPEG-2 coded video, non-zero AC DCT coefficients are removed from the MPEG-2 coded video to produce reduced-quality MPEG-2 coded video that includes no more than a selected number of largest magnitude quantization indices for the non-zero AC DCT coefficients for each 8×8 block.

Abstract translation: 对原始图像中的像素块的变换系数进行量化，以产生用于像素块的各组量化索引。 通过使用在每个块内不均匀的量化步长来产生至少一些块的量化索引。 从用于（运行，电平）编码的各组量化索引中选择最大幅度量化索引以产生（运行，电平）编码图像。 例如，MPEG-2编码视频包括用于8×8个像素块的一组非零AC离散余弦变换（DCT）系数。 为了缩放MPEG-2编码视频，从MPEG-2编码视频中去除非零AC DCT系数，以产生低质量的MPEG-2编码视频，该视频包括不超过非选择数量的非最大幅度量化索引， 每个8×8块的 - 零AC DCT系数。

Abstract: To permit multiple unsynchronized processors to update the file-modification time attribute of a file during concurrent asynchronous writes to the file, a primary processor having a clock manages access to metadata of the file. A number of secondary processors service client request for access to the file. Each secondary processor has a timer. When the primary processor grants a range lock upon the file to a secondary, it returns its clock time (m). Upon receipt, the secondary starts a local timer (t). When the secondary modifies the file data, it determines a file-modification time that is a function of the clock time and the timer interval, such as a sum (m+t). When the secondary receives an updated file-modification time (mp) from the primary, if mp>m+t, then the secondary updates the clock time (m) to (mp) and resets its local timer.

Abstract: A file server system having solid-state drive primary storage and magnetic disk drive secondary storage aggressively moves newly created files from the primary storage to selected file systems in the secondary storage to match expected access patterns upon the files to different configurations of the file systems and for load balancing upon the file systems in the secondary storage. Upon read access to a file that has been moved to the secondary storage, or upon migration of a newly created file that was read in primary storage after creation, a corresponding stub file containing file mapping metadata is created in the primary storage. The file mapping metadata in the stub file maps the extent of the file to logical storage addresses in the secondary storage.

Abstract: Interactive requests are processed from users of log-in nodes. A metadata server node is provided for use in a file system shared by one or more interactive nodes and one or more batch nodes. The interactive nodes comprise interactive clients to execute interactive tasks and the batch nodes execute batch jobs for one or more batch clients. The metadata server node comprises a virtual machine monitor; an interactive client proxy to store metadata requests from the interactive clients in an interactive client queue; a batch client proxy to store metadata requests from the batch clients in a batch client queue; and a metadata server to store the metadata requests from the interactive client queue and the batch client queue in a metadata queue based on an allocation of resources by the virtual machine monitor. The metadata requests can be prioritized, for example, based on one or more of a predefined policy and predefined rules.

Abstract: This invention is a system and a method for operating a storage server that provides read or write access to a data in a data network using a new architecture. The method of processing I/Os in response to a request by a client of the storage server executes one or more services communicated by a policy engine. The I/Os received from the application are tagged and catalogued to create co-related I/O patterns. The policy engine is then updated with the results of processing the I/Os after executing services on those I/Os.

Abstract: Interrupts and code threads are assigned in a particular way to the core CPUs of a network file server in order to reduce latency for processing client requests for file access. Threads of the network stack are incorporated into real time threads that are scheduled by a real-time scheduler and executed exclusively by a plurality of the core CPUs that are not interrupted by disk adapter interrupts so that the disk adapter interrupts do not interrupt execution of the network stack. Instances of a storage access driver are hard affinity threads, and soft affinity threads include a multitude of instances of a thread of the file system stack for file access request processing so that file access request processing for a multitude of concurrent file access requests is load balanced over the core CPUs.

Abstract: A file server includes active storage containing frequently accessed files, and active/inactive disk drives for containing infrequently accessed files. Groups of the files having become inactive in the active storage are successively migrated to respective evacuated active/inactive disk drives so that each active/inactive disk drive is loaded with files having a similar probability of access when access to the active/inactive disk drive reaches an inactivity threshold for powering down the active/inactive disk drive. Storage of the active/inactive disk drives is reclaimed when an oldest group of the files is archived or when an active/inactive disk drive is evacuated by migrating files from the active/inactive disk drive to storage having been released in other disk drives by promotion of files for client access to the promoted files. Therefore, recovery of storage can be planned and scheduled in advance and performed efficiently in a background process.

Abstract: Embodiments of the present invention are directed to techniques for selecting a data path over which to exchange information between a client device and a storage system by making a selection between a file system server (NAS) data path type (a first data path type) and a direct (SAN) data path type (a second data path type) based on one or more adjustable path selection factors and/or information regarding components of the computer system. For example, a data path may be selected based on one or more performance characteristics of a computer system in which a path selection module is acting and/or any other suitable path selection factor.
