    Abstract: A method for communicating with a device may include running, at a device, an operating system, communicating, using a first function of an interconnect, with the device, and communicating, using a second function of the interconnect, with the operating system. The operating system may include communication logic, and the communicating with the operating may include communicating with the communication logic. The communication logic may one or more terminal support drivers, and the communicating with the communication logic may include communicating with the one or more terminal support drivers using a terminal application. The terminal application may run on a host. The second function of the interconnect may be configured to operate with a controller. The communicating with the operating system may include communicating with the operating system based on a privilege information. The host may be a management controller. The method may further include controlling, using the second function of the interconnect, a program on the operating system.

    Abstract: Embodiments of the present disclosure are directed to a method for storing and processing data. The method includes identifying a database in a memory of a host device having one or more rows and one or more columns. A partition having a partition size is identified, and the one or more rows of the database is identified based on the partition size. The data stored in the one or more rows is converted into a column-based format, and the data is stored in a computational storage device in the column-based format. The computational storage device is configured to retrieve the data stored in the column-based format, in response to a query, and process the query based on the data.

    Abstract: A storage device is disclosed. The storage device may include storage to store data, which may include a first storage of a first type and a second storage of a second type. The storage device may support a number of device streams, some of which associated with the first storage and some associated with the second storage. The storage device may also include a streaming capabilities analyzer that may inventory the streaming capabilities for the storage device. Finally, the storage device may include a transmitter to transmit the streaming capabilities of the storage device to a storage manager.

    Abstract: A system and method for processing unstructured source data is described. Input data having a range of V is loaded from off-chip storage to on-chip storage. The input data is partitioned into P temporary parent partitions via the on-chip storage, where a particular one of the P temporary parent partitions has a range of V/P. The P temporary parent partitions are stored from the on-chip storage to the off-chip storage. The P temporary parent partitions are partitioned for generating P temporary child partitions until the target number of T partitions is generated, where data from of the P temporary parent partitions is source data for recursively loading, partitioning, and storing the source data. An application is configured to access partitioned data from the T partitions for generating an output. The accesses of the partitioned data are sequential read accesses of the off-chip storage.

    Abstract: Inventive aspects include a method, apparatus, and system for partitioning and processing graph data for large-scale graphs. Such may include, in a partitioning pre-processing step, assigning a plurality of destination vertices to a plurality of partitions such that each destination vertex of the plurality of destination vertices is uniquely assigned to only one partition from among the plurality of partitions. Such may also include, in a main execution of external graph processing step, (i) loading a given partition of destination vertices from among the plurality of partitions from a solid state drive (SSD) into a main memory of a computing machine, (ii) streaming one or more chunks of source vertex data from the SSD into the main memory of the computing machine, and (iii) performing graph processing based at least on the loaded given partition of destination vertices and the streamed one or more chunks of source vertex data.

    Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include a flash memory to store data and support for a number of device streams. The SSD may also include an SSD controller to manage reading data from and writing data to the flash memory. The SSD may also include a host interface logic, which may include a receiver to receive the commands associated with software streams from a host, a timer to time a window, a statistics collector to determine values for at least one criterion for the software streams from the commands, a ranker to rank the software streams according to the values, and a mapper to establish a mapping between the software streams and device streams.
