Abstract: A storage device is disclosed. The storage device may include compute engines. The compute engines may include storage for data, a storage processing unit to manage writing data to the storage and reading data from the storage, a data processing unit to perform some functions on the data, and an accelerator to perform other functions on the data. An Ethernet component may receive a request at the storage device from a host over a network. A data processing coordinator may process the request using a compute engine.

Abstract: Systems and methods for memory management are described. An example method can include: performing a first determination that may include: comparing a first parameter associated with a storage device to a second parameter associated with an application. In addition, the method may include performing a second determination based on the first determination, where the second determination may include: inserting data into a storage partition of the storage device; and determining to store a minimum processing unit associated with the data in the storage device.

Abstract: A storage device includes: protected memory including one or more log pages; non-volatile memory; and a storage controller. The storage controller includes: a command fetcher to receive a data request command associated with data including first metadata and second metadata, and execute the data request command in the non-volatile memory; a logger to identify the second metadata, and log the second metadata in the one or more log pages; and a log page fetcher/eraser to retrieve the second metadata from the one or more log pages in response to a separate command.

Abstract: A method for managing compute and I/O tasks in a data processing system includes: providing a thread pool including a plurality of thread groups, each thread group including one or more threads; providing a CPU pool including a plurality of CPU groups, each CPU group including one or more CPU cores; receiving a plurality of tasks comprising I/O tasks and compute tasks; mapping each of the plurality of tasks to at least one thread group in the thread pool; and mapping each of the plurality of thread groups in the thread pool to at least one CPU group in the CPU pool. The mappings between the plurality of tasks and the plurality of thread groups and between the plurality of thread groups and the plurality of CPU groups dynamically change based on performance variables.

Abstract: Systems and methods for processing and distributing a service request. The service request is received from a client, and a location of data is identified. A status of a computational storage device associated with the location is determined. The service request is transmitted to a storage service associated with the computational storage device based on the status. A response to the service request from the storage service, is identified, and the response is provided to the client.
