Abstract: Workload distribution in a system including a non-volatile memory device is disclosed. A request is received including an address associated with a memory location of the non-volatile memory device. A hash value is calculated based on the address. A list of node values is searched, and one of the node values in the list is identified based on the hash value. A processor is identified based on the one of the node values, and the address is stored in association with the processor. The request is transmitted to the processor for accessing the memory location.

Abstract: A device is disclosed. The device may include an input buffer to receive a first low bit width message. A reconstruction circuit may implement a reconstruction function on the first low bit width message, producing a first high bit width message. A computation circuit may implementing a computation function on the first high bit width message, producing a second high bit width message. A quantization circuit may implementing a quantization function on the second high bit width message, producing a second low bit width message. A decision buffer may then store the second low bit width message. The reconstruction function and the quantization function may vary depending on an iteration and a layer of the device.

Abstract: According to one general aspect, an apparatus may include a regeneration-code-aware (RCA) storage device configured to calculate at least one type of data regeneration code for data error correction. The RCA storage device may include a memory configured to store data in chunks which, in turn, comprise data blocks. The RCA storage device may include a processor configured to compute, when requested by an external host device, a data regeneration code based upon a selected number of data blocks. The RCA storage device may include an external interface configured to transmit the data regeneration code to the external host device.
