摘要： A system and method for maintaining data coherency in a system in which data is replicated on two or more servers. Each server is able to update the data replica present on the server. Updates are logged for each server. Reconciliation of server data replicas is aggressively initiated upon the occurrence of predefined events. These events include arrival at a scheduled time, a request for data by a client system, server and network failure recovery. Reconciliation is managed by a coordinator server selected to ensure that at most one coordinator server per network partition is selected. Logged updates are merged and transmitted to each server containing a data replica. The logged updates are applied unless a conflict is detected. Conflicts are collected and distributed for resolution. Reconciliation is managed between servers without regard to operating system or physical file system type.

摘要： In an information processing system including a file shared by computer systems each having a central processing system and a main memory, a method for controlling access to the shared file includes a step of storing blocks read from the file into the main memory when the blocks of the file are updated, and a step of comparing at least a portion of the blocks held in a cache memory with at least a portion of the blocks stored in the main memory. When the comparison of at least the portion of the blocks held in the cache memory with at least the portion of the blocks stored in the main memory indicates mismatching, the block is read from the file into the main memory, and when the comparison indicates matching, the block of the main memory is updated. The data to be updated may be in a resident area, an input/output buffer or a same area.

摘要： A computing system is specifically adapted for the performance of vector operations. A computing system takes two vector streams and orders the elements of those vector streams into a single ordered vector stream. Each vector stream is received in a different receiver register with each vector being clocked down through the computing system. The elements of the vector streams are compared and ordered into a single ordered vector stream.

摘要： A computer implemented method for classifying at least one source dataset of a computer system. The method may include providing a plurality of associated reference tables organized and associated in accordance with a reference storage model in the computer system. The method may also include calculating, by a data classifier application of the computer system, a first similarity score between the source dataset and a first reference table of the reference tables based on common attributes in the source dataset and a join of the first reference table with at least one further reference table of the reference tables having a relationship with the first reference table. The method may further include classifying, by the data classifier application, the source dataset by determining using at least the calculated first similarity score whether the source dataset is organized as the first reference table in accordance to the reference storage model.

摘要： An imprint apparatus forms a pattern on a substrate by curing an imprint material on the substrate while the imprint material is in contact with a mold. The imprint apparatus includes a substrate chuck having a substrate holding region for holding the substrate, a peripheral member arranged to surround the side surface of the substrate held by the substrate chuck, and a control unit configured to control a cleaning process for cleaning at least a partial region of the peripheral member by using a cleaning member including a charging unit. The cleaning process includes an operation for attracting a particle in the partial region to the charging unit by moving the cleaning member relative to the peripheral member while the charging unit faces at least the partial region of the peripheral member.

摘要： The present disclosure is directed toward systems, methods, and non-transitory computer readable media for generating an identity resolution model from a ground truth data set to accurately match users across one or more digital content providers to perform analyses of user activities across the one or more digital content providers. For example, the systems described herein can generate a ground truth data set of known users and utilize the ground truth data set to generate an identity resolution model for one or more digital content providers based on predicted user identities. Furthermore, in one or more embodiments, the systems utilize the identity resolution model to accurately resolve and match user identities between one or more digital content providers and assign universal identifiers to the user identities. Moreover, the disclosed systems can utilize the universal identifiers to provide analytical insights of user actions between the one or more digital content providers.

摘要： A method for detecting a domain name that is associated with malicious behavior includes receiving domain data for a plurality of domain names including a first domain name and a plurality of similar domain names. The domain data includes a first attribute and a second attribute of the first domain name and the similar domain names. The first attribute of the first domain name is compared to the first attributes of the similar domain names to produce a first value. The second attribute of the first domain name is compared to the second attributes of the similar domain names to produce a second value. The first value and the second value are combined to produce a combined value. A likelihood that the first domain name is associated with malicious behavior is determined based on the combined value.

摘要： Multiple items of first address information are identified by a server associated with a first service provider. Each item of first address information is identified from a corresponding item of first account information provided by the first service provider. Multiple items of second address information are identified by the server. Each item of second address information is identified from a corresponding item of second account information provided by a second service provider. For each item of first address information, a determination is made, by the server, that an item of second address information matches the particular item of first address information, and a mapping relationship is established, by the server, between an item of first account information, corresponding to the particular item of first address information, and an item of second account information, corresponding to the item of second address information.
