  • Patent number: 11662910
    Abstract: A data storage system has multiple tiers of data storage including an upper tier having a lower access latency and a lower tier having a higher access latency. A storage controller of the data storage system receives, via an interface, an access request of a workload for a target file system object, where the target file system object has an associated temperature. In response to the access request for the target file system object, the storage controller accesses the target file system object in the data storage and conditions update of the associated temperature of the target file system object based on at least one of a set including the interface and the workload. The storage controller distributes a collection of file system objects including the target file system object among the multiple tiers based on respective heats of file system objects in the collection.

  • Patent number: 11662989
    Abstract: Pointer alignment in a computer programming to obtain information enabling a compiler to optimize program code. Equivalence classes of pointers are collected in a program using a flow-insensitive yet field-sensitive pointer analysis operation iterating through an entire program code of the program. The equivalence classes of pointers, once collected, are mapped to and recorded in an equivalence class mapping table (ECTable). A portion of the collected equivalence classes of pointers are identified, from the ECTable, as pointer candidates for a pointer alignment computation according to a code pattern analysis of each pointer candidate. The code pattern analysis is based on available alignment information, and whether the alignment information would enable a compiler to optimize pointer references of the candidate pointer. The pointer alignment computation is then performed for each identified pointer candidate to obtain the alignment information used to optimize execution of the program.

The framework uses homomorphic encryption. The data may be gallery entities, and each of the elements in the framework operate on doubly-encrypted information. The service provider compares a representation of an encrypted query entity from the querying agency and representations of encrypted gallery entities from the data owning agency, resulting in doubly-encrypted values of a metric between corresponding compared representations. The querying agency gets result(s), based on the metric, which indicate whether it is probable the service provider has data similar to or the same as query data in the query entity. The elements have to perform communication in order for the querying agency or the data owning agency to get cleartext information corresponding to the query entity.

  • Patent number: 11663060
    Abstract: A call for communication is detected between applications, where the call requires input from a plurality of threads of the applications via editing of a single control message in a queue such that the single control message reflects data from each of the applications. An attempt by a first of the plurality of threads to edit the single control message is detected while a second of the plurality of threads is editing the single control message. A message is sent to the first of the plurality of threads that details a status of the single control message in response to detecting the attempt. The call for communication is responded to using the single control message in response to detecting that each of the plurality of threads has edited the single control message.

  • Patent number: 11663159
    Abstract: A method, apparatus, system, and computer program code for policy-based enforcement in a data virtualization system is provided. Responsive to receiving a query, a computer identifies a virtual object among a set of connected objects that is represented by a set of data assets and their hierarchical relationships. The virtual object corresponds to a subset of the data assets. The computer identifies a subset of objects according to a cumulative transitive closure of the virtual object over the set of connected objects. The computer identifies a set of policies for the subset of objects. For each object in the subset of objects, the computer determines an intermediate decision according to set of policies, whereby a set of intermediate decisions is formed. The computer deterministically reconciles the set of intermediate decisions to generate a resolved decision. The computer provides access to the queried virtual objects based on the resolved decision.

  • Patent number: 11663215
    Abstract: A computer system includes a natural language processing (NLP) unit, a storage unit, a user interface and a search engine. The NLP unit analyzes a content source to identify one or more sections containing searchable content and generate section metadata respective to each identified section included in the content source. The storage unit stores the section metadata and the user interface receives a section-scoped query aimed at searching an identified section corresponding to the at least one first section metadata stored in the storage unit without searching an identified section corresponding to at least one second section metadata stored in the storage unit. Based on the section-scoped query, the search engine analyzes the at least one first section metadata stored in the storage unit without analyzing the at least one second section metadata.

  • Patent number: 11663270
    Abstract: An instruction is provided for performing a vector string search. The instruction to be processed is obtained, with the instruction being defined to be a string search instruction to locate occurrence of a substring within a string. The instruction is processed, with the processing including searching the string specified in one operand of the instruction using the substring specified in another operand of the instruction. Based on the searching locating a first full match of the substring within the string, a full match condition indication is returned with position of the first full match in the string, and based on the searching locating only a partial match of the substring at a termination of the string, a partial match condition indication is returned, with the position of the partial match in the string.

  • Patent number: 11663067
    Abstract: Embodiments of the invention include a computer-implemented method for detecting anomalies in non-stationary data in a network of computing entities. The method collects non-stationary data in the network and classifies the non-stationary data according to a non-Markovian, stateful classification, based on an inference model. Anomalies can then be detected, based on the classified data. The non-Markovian, stateful process allows anomaly detection even when no a priori knowledge of anomaly signatures or malicious entities exists. Anomalies can be detected in real time (e.g., at speeds of 10-100 Gbps) and the network data variability can be addressed by implementing a detection pipeline to adapt to changes in traffic behavior through online learning and retain memory of past behaviors. A two-stage scheme can be relied upon, which involves a supervised model coupled with an unsupervised model.
