Abstract: An approach for identifying missing content is provided. An approach includes: receiving a search string; determining a skill rating associated with a searcher that generated the search string; and searching a database using the search string. The approach also includes: updating at least one of a first score associated with the search string and a second score associated with the database based on the skill rating; and generating an alert based on one of the first score exceeding a first threshold and the second score exceeding a second threshold.

Abstract: Methods and apparatuses that maintain birth time for a file system to optimize file update operations are described. The file system can include a plurality of snapshots or clones of data stored in one or more extents of blocks allocated in a storage device. Each extent may be associated with a time stamp according to the birth time. A request may be received from an executable using the file system to update data in a particular extent associated with a particular time stamp. In response, the current birth time in the file system and the particular time stamp may be compared to determine if the particular extent is not shared by more than one of the snapshots. If the particular time stamp is equal to the current birth time, the particular extent may be updated directly without performing an expensive operation to check whether a reference count of the particular extent is equal to one.

Abstract: Embodiments of the present invention provide a method, system and computer program product for mapping models to relational databases for reporting tools. In an embodiment of the invention, a model mapping method for models of a model driven development (MDD) environment can include initializing a database table and selecting a data source storing a modeling framework representation of a model. A first query can be executed against an application programming interface (API) of the data source supporting a modeling framework query language to retrieve selected elements of the model. Likewise, a second query can be executed against the API of the data source to retrieve selected attributes of the selected elements of the model. Finally, rows of the database table can be populated with the retrieved selected elements of the model and corresponding columns of the database table can be populated with the retrieved selected attributes of the selected elements of the model.

The method further includes locking the first chunk in response to determining that the first chunk is available for editing, sending, to the first editor, a first message indicating that the first chunk has been locked, and sending, to a second editor, a second message indicating that the first chunk has been locked.

Abstract: An aspect of synchronization of time between simulation models includes receiving a specification request for generating a set of target time-series data using a set of source time-series data, obtaining specification information relating to the set of source time-series data, obtaining specification information relating to the set of target time-series data and obtaining the source time-series data; comparing the source specification information and the target specification information to determine if the set of source time-series data are time-aligned with the set of target time-series data, and converting the set of source time-series data to the set of target time-series data upon determination that time alignment is needed.

Abstract: Method and apparatus to provide synchronizing first and second volumes in a continuous data protection system as part of an initialization process, identifying locations in the first and second data volumes having data differences, identifying data locations for entries in a data stream of undistributed data, creating a dirty location map indicating for locations in the first and second volumes whether there is an entry in the data stream, and examining the dirty location map and transmitting data signatures for the identified locations having data differences and not flagged in the dirty location map.

Abstract: A network's evolution is characterized by graph evolution rules. A graph, formed by merging multiple graphs representing the multiple snapshots of the network, that represents an evolutionary network is mined to identify evolutional patterns of the network. A pattern is selected from the identified patterns. Graph evolution rules are generated using identified evolutional patterns. The generated graph evolution rules represent the evolutional patterns of the network, the rules indicating that any occurrence of a child pattern of the selected pattern implies a corresponding occurrence of the selected pattern.

Abstract: A system and method for application aware de-duplication of data blocks in a virtualized storage array is disclosed. In one embodiment, in a method of de-duplication of data, a master list of metadata is created based on a number of occurrences of data blocks within a storage array. A first sublist of metadata is created from the master list of metadata. The first sublist of metadata is provided to a first component of a networked storage system. It is determined whether the data block being written has a corresponding entry in the master list of metadata based on a determination that a data block being written does not have any corresponding entry in the first sublist of metadata. The data block being written is replaced with a pointer based on a determination that the data block being written has a corresponding entry in the master list of metadata.

Abstract: Techniques for optimizing a search are disclosed. In one embodiment, a method for optimizing search on a Web site comprises: receiving from a client computing device a first search request including a first search term, retrieving and rendering to the client computing device first search results including one or more items corresponding to the first search term included in the first search request, receiving from the client computing device a second search request associated with an item of the one or more items rendered with the first search results, retrieving one or more second search terms behaviorally associated with the selected item, and retrieving and rendering to the client computing device second search results corresponding to the one or more second search terms. The second search results may be rendered “in-line.

Abstract: A method for locking resources, including: receiving, by an accelerator, a first request from a first client to lock a first resource; evaluating, by a computer processor of a server, a hash function using an identifier of the first resource as an input to the hash function; identifying, by the computer processor and based on evaluating the hash function, a first hash bucket in a shared memory residing in a physical memory of the server; detecting that the first hash bucket is occupied; and sending the first request to a master lock monitor residing in a user space of the server based at least on detecting that the first hash bucket is occupied.

Abstract: Mechanisms are provided for efficient resynchronization of replicated data. A hash value is generated for a chunk of data replicated from a source node to a target node. The chunk of data may be a file deduplicated and compressed at both a source node and a target node. A current sequence number is determined and a sequence number and hash tuple is maintained for the chunk of data at both the source node and the target node. Sequence numbers are modified whenever the data is modified. Current sequence numbers and sequence number and hash values in the sequence number hash tuples at the source node and the target node may be compared to determine whether data is still synchronized at a later point in time or whether data requires resynchronization.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for distributing content are disclosed. In one aspect, a method includes accessing data specifying a plurality of search queries. Content distribution campaigns (“campaigns”) in which distribution of at least one content item is conditioned on a distribution parameter matching one of the search queries are identified. Two or more similar campaigns are identified, and a search query that matches a distribution parameter in at least one of the similar campaigns is identified as a candidate content distribution parameter. A trend score for the candidate content distribution parameter is determined based on a change in a submission rate of search queries that match the candidate distribution parameter. Suggestion data suggesting the candidate content distribution parameter as an additional content distribution parameter for at least one of the similar campaigns is provided based on the trend score.
