Abstract: A method, a device and computer program for recording a plurality of events in an encoded tracer variable in a security-oriented computer program, wherein each event is recorded as a value in the encoded tracer variable, where in order to simultaneously record multiple events from the values for the events, a total value is first calculated which is then recorded in the encoded tracer variable, such that multiple independent consistency criteria can be advantageously processed simultaneously to detect and propagate errors or other events and such that by virtue of the simultaneous processing, many dynamic effects are prevented during the detection and propagation of errors/events, thus allowing for the necessary reduced complexity of security programs.

Abstract: Techniques are described for identifying root cause anomalies in time series. Information to be used for root cause analysis (RCA) is obtained from a graph neural network (GNN) and is used to construct a dependency graph having nodes corresponding to each time series and directed edges corresponding to dependencies between the time series. Nodes corresponding to time series that do not contain anomalies may be removed from this dependency graph, as well as edges connected to these nodes. This edge and node removal may result in the creation of one or more sub-graphs from the dependency graph. A root cause analysis algorithm may be run on these one or more sub-graphs to create a root cause graph for each sub-graph. These root cause graphs may then be used to identify root cause anomalies within the multiple time series, as well as sequences of anomalies within the multiple time series.

Abstract: Aspects of the disclosure are directed to a low-latency, low-overhead fault tolerant remote memory framework, which packs similar-size in-memory objects into individual page-aligned spans and applies erasure coding on these spans. The framework fully utilizes efficient one-sided remote memory accesses (RMAs) to swap spans in and out using minimal network input/outputs (I/Os), with compaction techniques that reduce remote memory fragmentation. The framework can achieve lower tail latency and higher application performance compared to other fault tolerance solutions, at the cost of potentially more memory usage.

Abstract: Various devices, such as storage devices or storage systems are configured to avoid ungraceful shutdowns utilizing recycled power. Storage devices typically generate heat during normal operations. Energy recycling modules disposed on various components of the storage device recycle this heat. This recycled heat can be captured and converted into electricity that can be stored for later discharge and use. These energy recycling modules can be a series of semiconductors that utilize various natural effects to convert heat applied on one side of the module into electricity that can be delivered to various power storing components. The stored power can be utilized in the event of a sudden power loss in order to power one or more components necessary to perform a graceful shutdown. In this way, even when power is totally cut off from the storage device, there is enough stored recycled electricity that an ungraceful shutdown can be avoided.
