    Abstract: Systems and methods for prefetching data are disclosed. A processor executes a first command for moving first data stored in a storage device. Based on the first command, the processor stores, into a first queue of the storage device, a first address associated with the first data. The storage device further retrieves the first address from the first queue, retrieves the first data from the first storage medium based on the first address, and stores the first data to the second storage medium. In some embodiments, a process for prefetch optimization is also disclosed. A processor identifies a value for prefetching data. The processor runs an application, measures performance of the application, modifies the value based on the performance, and determines that the performance satisfies a criterion.

    Abstract: Inventive aspects include a polar code encoding system, which includes a partitioning unit to receive and partition input data into partitioned input data units. Encoders encode the partitioned input data units, and generate encoded partitioned input data units. Multiplier units perform matrix multiplication on the partitioned input data units and generator matrices, and generate matrix products. Adder units perform matrix addition on the encoded partitioned input data units and the matrix products. A combining unit combines outputs of the encoders into a target code word X. The target code word X may be a length-N code word X, where N=N1+N2+ . . . +Nm, where each of N1, N2, through Nm are a power of two (2).

    Abstract: A method for memory access may include receiving, at a device, a first memory access request for a parallel workload, receiving, at the device, a second memory access request for the parallel workload, processing, by a first logical device of the device, the first memory access request, and processing, by a second logical device of the device, the second memory access request. Processing the first memory access request and processing the second memory access request may include parallel processing the first and second memory access requests. The first logical device may include one or more first resources. The method may further include configuring the first logical device based on one or more first parameters of the parallel workload. The method may further include allocating one or more first resources to the first logical device based on at least one of the one or more first parameters of the parallel workload.
