摘要： A technique for block data transfer is disclosed that reduces data transfer and memory access overheads and significantly reduces multiprocessor activity and energy consumption. Threads executing on a multiprocessor needing data stored in global memory can request and store the needed data in on-chip shared memory, which can be accessed by the threads multiple times. The data can be loaded from global memory and stored in shared memory using an instruction which directs the data into the shared memory without storing the data in registers and/or cache memory of the multiprocessor during the data transfer.

摘要： A system comprising a gateway for interfacing external data sources with one or more accelerators. The gateway comprises a plurality of virtual gateways, each of which is configured to stream data from the external data sources to one or more associated accelerators. The plurality of virtual gateways are each configured to stream data from external data sources so that the data is received at an associated accelerator in response to a synchronisation point being obtained by a synchronisation zone. Each of the virtual gateways is assigned a virtual ID so that when data is received at the gateway, data can be delivered to the appropriate gateway.

摘要： Systems and methods are described for processing ingested data using an online machine learning algorithm as the data is being ingested. For example, the online machine learning algorithm can be an adaptive thresholding algorithm used to identify outliers in a moving window of data. As another example, the online machine learning algorithm can be a sequential outlier detector that detects anomalous sequences of logs or events. As another example, the online machine learning algorithm can be a sentiment analyzer that determines whether text has a positive, negative, or neutral sentiment. As another example, the online machine learning algorithm can be a drift detector that detects whether ingested data marks the start of a change in the distribution of a time-series.

摘要： Example inter-process communication methods and apparatus are descried. One example method includes writing, based on a calling convention, communication information into a register group of a first execution entity of a sending process. First data of target data is written into a stack memory of the first execution entity. The communication information includes a first value indicating a data amount of the first data, and the target data is data to be sent by the sending process to a first receiving process. Information in the register group of the first execution entity is replicated to a context of the first execution entity. The first data from the stack memory of the first execution entity is replicated to a stack memory of a second execution entity of the first receiving process based on the first value in the context of the first execution entity and the address of the stack memory.

摘要： The present disclosure is related to performing speculation in, for example, a memory device or a computing system that includes a memory device. Speculation can be used to identify data that is accessed together or to predict data that will be accessed with greater frequency. The identified data can be organized to improve efficiency in providing access to the data.

摘要： In an example embodiment, a solution is used to provide container volume replication via a container storage replication log and volume buffer synchronization, which is built on top of a container cloud platform whose container metadata and replication runtime configuration are all managed by a storage manager (a service orchestrated by its job scheduler and service orchestrator). This container volume replication ensures the data security for a long-running service in the container. In the case of any disaster, the in-memory database and application data inside of the container can be recovered via volume replication. This provides container volume replication for long-running containerized applications whose states keep changing.

摘要： A method includes creating a publisher configured to send messages over a channel having a shared memory. The method includes creating at least one subscriber configured to receive the messages over the channel by sequentially referencing memory slots of the plurality of memory slots. The method includes determining that the next sequential memory slot is currently referenced by a subscriber. The method includes delaying sending the message by the publisher based on determining that the next sequential memory slot is currently referenced by the subscriber. The method includes receiving an event trigger indicative of message reading by the subscriber. The method includes, responsive to receiving the event trigger, determining that the next sequential memory slot is not currently referenced. The method includes sending the message to the next sequential memory slot based on determining that the next sequential memory slot is not currently referenced.

摘要： A storage system and method for secure host controller memory buffer access are provided. In one embodiment, a storage system is provided comprising a storage area configured to store a database comprising a submission queue and a completion queue dedicated for use by an authorized host, and a controller. The controller is configured to: receive a request to access the storage area; determine whether the request is from the authorized host or from an unauthorized host; in response to determining that the request is from the authorized host, grant the request; and in response to determining that the request is from an unauthorized host, deny the request. Other embodiments are provided.
