Abstract: A topology aware distributed storage system includes a plurality of storage nodes, at least one client node, and a storage manager and metadata store. A user-defined storage policy specifies where data is stored within a topological hierarchy of nodes within the network. A hierarchical ring topology including a hierarchical structure of rings representing an organizational structure of nodes is computed and flattened into a single global ring divided into segments corresponding to a unique range of integers and associated with a replica set responsible for storing a key corresponding to one of the integers. A hash function is performed on a user key received from the client node, and the hashed key is looked up on the flattened global ring stored on each storage node to identify the replica set responsible for storing data corresponding to the hashed key.

Abstract: A system that can detect when abnormal trading activity is occurring and take action to halt the detected abnormal trading activity without human intervention using a computer-implemented anomaly detection and action stage that performs an exponential weighted averaging of trade order flow, on a per symbol basis within a sliding volume based window and a volume based exponential weighted averaging, on a per symbol basis, on trade update messages received during the sliding volume based window and checks for an inflection in covariance between them. A related method is also described.

Abstract: A data feeds platform, comprising a data feed using a data feed protocol. The data feed protocol comprises, a feed header defining at least one identification attribute, a data header defining a data structure comprising data nodes, each data node corresponding to a subset of the data, and a data section, the data section storing the data according to the data structure. A plurality of heterogeneous data protocols is stored. A data input is received in one of the plurality of heterogeneous data protocols. The data input is converted to the data feed protocol, creating the data feed.

Abstract: A computerized method of identifying accounts stored in a database of an account management system, for review under jurisdictionally relevant CIP/AML/KYC requirements is described, as is a computerized account database access tool having a data extraction module, an inclusion rules module, an exclusion rules module and a merge and aggregate module.

Abstract: A data slot may be reserved for a first thread selected from a plurality of threads executed by a computer system. A memory of the computer system may comprise a plurality of log files and a next free data slot pointer. Each log file may comprise a plurality of data slots and each of the data slots may be of a common size. Reserving the data slot for the first thread may comprise attempting to perform a first atomic operation to write to a first data slot pointed to by a current value of the next free data slot pointer an indication that the first data slot is filled. If the first atomic operation is successful, the computer system may update the next free data slot pointer to point to a second data slot positioned sequentially after the first data slot. If the first atomic operation is unsuccessful, the computer system may analyze the second data slot.

Abstract: Computer-implemented systems and methods for managing virtual computing services. A service interface may receive from an administrative user an instruction indicating a configuration change for a first virtual computing service. A plurality of agents comprises a leader agent and at least one other agent. The leader agent may assign to the at least one other agent a plurality of jobs for implementing the configuration change. The at least one other agent may execute at least one of the plurality of jobs, where executing the at least one of the plurality of jobs comprises modifying a configuration of a virtual desktop site associated with the first virtual computing service.

Abstract: Various embodiments are directed to systems and methods for offering a security to potential investors. In various embodiments, a plurality of bids may be received on the security. The bids may be divided by investors into a plurality of investor segments. One of the investor segments may comprise potential investors who are customers of the issuer of the securities. The shares of the offering may be divided into a plurality of tranches where each of the tranches corresponds to one of the investor segments. Shares in a first tranche may be allocated to the corresponding investor segment according to a first allocation method. Shares in a second tranche may be allocated to the corresponding investor segment according to a second allocation method.

Abstract: A method for performing a calculation that includes determining solutions for a plurality of problem modules. The problem modules are of differing complexities, and their solutions are combined to determine a solution to the calculation. The method may include directing each of the problem modules to at least one master server, estimating a complexity for each of the problem modules, determining a threshold complexity level, sending problem modules having a complexity exceeding the threshold complexity level to at least one slave server and obtaining solutions for the problem modules therefrom, determining solutions for problem modules having a complexity not exceeding the threshold complexity level in the master server(s), and combining the solutions for the problem modules to determine the solution for the calculation.

Abstract: A user interface for providing information regarding a subject company to a user. The user interface may comprise a company tile, which may have an indicator of the subject company. A state of the company tile, such as, for example, its color, may indicate a property of the subject company.
