Radu Berinde Thesis

The general problem of obtaining a useful succinct representation (sketch) of some piece of data is ubiquitous it has applications in signal acquisition, data compression, sub-linear space algorithms, etc. The block attribute parity value and the data parity value are stored on one of the physical storage devices in response to the received write request. The client computer submits the user-identified document link to a server remotely located from the client computer.

Wenguang wang, radu berinde, christos karamanolis, jorge guerra delgado, srinath premachandran techniques for efficiently storing the state of an in-memory table to persistent storage are described. We also present two iterative recovery algorithms, sparse matching pursuit and sequential sparse matching pursuit, that can be used with the same matrices. The server computer queries a cached document server for a document link to a cached copy of a document corresponding to the user-identified document link.

We consider two types of sketches linear and non-linear. In this thesis we focus on sparse recovery, where the goal is to recover sparse vectors exactly, and to approximately recover nearly-sparse vectors. The second set of the logical pointer objects may point to physical data blocks having deduplicated data that comprise data of the corresponding logical data blocks.

A server computer performs multiple operations in response to a user-identified inoperative document link. A block attribute of a second block is determined. The server computer extracts one or more query terms from the user-identified document link.

We show that the errors in the approximations generated by these algorithms do not grow with the frequencies of the most frequent elements, but only depend on the remaining tail of the frequency vector. See provided url for inquiries about permission. We show that they can be used with the popular geometric 1 minimization recovery procedure.

The uniqueness metric may be used to identify files for rebalancing in the distributed storage system. Exemplary methods, apparatuses, and systems maintain hole boundary information by calculating a block attribute parity value. As a result, if a disk is lost, holes can be recovered using the block attribute parity value. A uniqueness metric for each file may indicate a degree of deduplication of the respective data files in the given storage volume. Eric knauft, luke lu, wenguang wang, pascal renauld, radu berinde, ruocheng li a method and system are disclosed for storing client data objects in a deduplicated storage system.

    The replication of a group of data sets is coordinated into a single schedule based on the recovery point objective (rpo) of each data set. A snapshot or clone may be created by making a copy of the root and associating the copied root with the snapshot or clone. The second set of the logical pointer objects may point to physical data blocks having deduplicated data that comprise data of the corresponding logical data blocks. A client computer having one or more processors and memory, while displaying a browser application having a displayed address field, receives a user-identified document link. Wenguang wang, radu berinde, christos karamanolis, jorge guerra delgado, srinath premachandran techniques for efficiently storing the state of an in-memory table to persistent storage are described.

    A second set of the logical pointer objects may be associated with corresponding logical data blocks of a client data object. The client computer submits the user-identified document link to a server remotely located from the client computer. We also show experiments which establish the practicality of these algorithms. At least one of the query terms is different from the user-identified document link. A block attribute of a second block is determined.

    The server computer extracts one or more query terms from the user-identified document link. A server computer performs multiple operations in response to a user-identified inoperative document link. One or more historical entries in the table are selected and one or more historical redo log entries that correspond to the one or more historical entries are generated. Therefore, they provide a non-linear sparse recovery scheme, achieving compression rates that are an order of magnitude better than their linear counterparts. File granular data de-duplication effectiveness metric for data de-duplication in accordance with the present disclosure, files may be deduplicated in a distributed storage system having a plurality of storage volumes. See provided url for inquiries about permission. If necessary bandwidth exceeds available bandwidth, the resulting generated schedule attempts to best satisfy each data sets rpo requirements given the available bandwidth. The deduplicated data may be mapped to logical data blocks that comprise the client data objects. The uniqueness metric may be used to identify files for rebalancing in the distributed storage system. The server computer returns at least one of the extracted query terms, the candidate document links, and the document link to the cached copy to the client computer.

    The server computer returns at least one of the extracted query terms, the candidate document links, and the document link to the cached copy to the client computer. The sparse recovery problem has been subject to extensive research over the last few years, notably in areas such as data stream computing and compressed sensing. For the non-linear case, we present a better analysis of a class of counter algorithms which process large streams of items and maintain enough data to approximately recover the item frequencies.

    One or more historical entries in the table are selected and one or more historical redo log entries that correspond to the one or more historical entries are generated. For the linear sketching case, where the compressed representation of x is ax for a measurement matrix a, we introduce a class of binary sparse matrices as valid measurement matrices. The block attribute parity value and the data parity value are stored on one of the physical storage devices in response to the received write request. The uniqueness metric may be used to identify files for rebalancing in the distributed storage system.
