Abstract: Systems and methods are described for managing high volumes of alerts to increase security, reduce noise, reduce duplication of work, and increase productivity of analysts dealing with and triaging alerts. A work unit queue may be configured to buffer or smooth workflows and decouple heavy processing which may improve performance and scalability to prevent duplicate assignments. Queueing services provide lag times to prevent over-assignment or double assignment of alerts to work units. System security may be improved by creating an authentication or verification step before allowing users to update alert statuses such that only users with work unit tokens that match alert tokens may update alert statuses.

Abstract: Various embodiments include techniques for performing speculative remote memory operation tracking in a multiprocessor computing system. Conventionally, transfers of data between processors and other components of a computing system require memory synchronization operations to determine that the data is valid and coherent before the data is transferred from a destination to a requesting source. Existing techniques for performing these memory synchronization operations are increasingly inefficient as the number of components in a computing system increases, particularly for remote memory operations. The disclosed techniques track remote memory operations and speculatively perform these memory synchronization operations. As a result, a given memory synchronization operation is often complete prior to the corresponding remote memory operation arrives at the destination, leading to improved efficiency and performance of remote memory operations in complex computing systems.

Abstract: Methods and systems for a retractable handheld exercise apparatus. The methods and systems generate a movement similar to upper body ski poling whereby a pair of handheld units [A] are connected to a fixed object by an attachment means [B] and are moved in an upper body walking motion to and from the fixed attachment point along a cable [C]. The apparatus includes functionality to increase or decrease tension which changes the amount force required to pull the unit away from the fixed point. In this way, the apparatus provides a simulation of uphill or downhill movements. Models with greater relative tension could be offered for individuals of greater weight as well as those who desire more vigorous exercise. Handles with varying sizes and cords of varying length would accommodate individuals with different hand and arm size, respectively. Handles with greater absolute weight would increase the difficulty overall while removable weight bands allow users to vary the weight of the unit by routine.
