    Abstract: A method may include receiving, from a process, a memory allocation request for a memory system comprising a first channel having a first channel utilization and a second channel having a second channel utilization, selecting, based on the first channel utilization and the second channel utilization, the first channel, and allocating, to the process, a page of memory from the first channel. The selecting may include selecting the first channel based on a balanced random policy. The selecting may include generating a ticket based on a random number and a number of free pages, comparing the ticket to a number of free pages of the first channel, and selecting the first channel based on the comparing. The selecting may include selecting the first channel based on a least used channel policy.

    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: A system is disclosed. The system may include a processor that may issue a byte level protocol request including a byte address. The system may also include a first storage device and a second storage device. The first storage device and the second storage device may support a cache coherent interconnect protocol, the cache coherent interconnect protocol including a block level protocol and a byte level protocol. The first storage device and the second storage device are included in a redundant array of independent disks (RAID). The first storage device may include a first address range, and the second storage device may include a second address range. The second storage device may provide a RAID address range associated with the first address range and the second address range. A decoder associated with the second storage device may be configured to receive the request from the processor. The decoder may determine that the byte address in the RAID address range is associated with a target address range.

    Abstract: Systems and methods for prefetching data are disclosed. A processor in communication with a storage device identifies a first address. The processor identifies a first setting associated with the first address. The processor issues a first command to a first storage medium of the storage device based on the first setting. The first command is for performing a first type of memory read. The storage device is configured to retrieve first data associated with the first address in the first storage medium, to a second storage medium of the storage device, based on the first command.
