Abstract: A Solid State Drive (SSD) is disclosed. The SSD may include ports to receive requests from a host and to send requests to a second storage device. The SSD may include flash storage for data. An SSD controller may process the requests received from the host and generate the requests sent to the second storage device. The SSD may act as a cache for the second storage device.

Abstract: An apparatus is disclosed. The apparatus may include a storage device, which may store a database including a table. The apparatus may also include an accelerator connected to the storage device. The accelerator may include a kernel. A scan, associated with a query, may access data from the table in the database stored on the storage device. A scan priority calculator may calculate a priority of the scan. A kernel assignment unit may assign the kernel to the scan based at least in part on the priority of the scan.

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 system and method for two-level indexing for key-value persistent storage. The method may include: sorting two or more key-value pairs to form a sorted key-value pair set; determining an address of a first key-value pair of the key-value pairs, the first key-value pair including a first key and a first value; determining an address of a second key-value pair of the key-value pairs, the second key-value pair including a second key and a second value; and training a first linear regression model to generate a first line corresponding to the key-value pairs, the training including training the first linear regression model with key-value pairs including the first key-value pair and the second key-value pair.

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.
