Abstract: A method includes sending, from an application layer, a chunk size setting to an erasure coding layer. The method further includes receiving, at the application layer, user data. The method further includes aligning, at the application layer, the user data based on the chunk size setting. The method further includes sending the aligned user data to the erasure coding layer. The method further includes partitioning, at the erasure coding layer, the aligned user data into a first data chunk and a second data chunk. The method further includes generating, at the erasure coding layer, a parity chunk based on the first data chunk and the second data chunk. The method further includes sending, from the erasure coding layer, the first data chunk, the second data chunk, and the parity chunk to a storage system.

Abstract: A storage device is disclosed. The storage device may comprise storage for input encoded data. A controller may process read requests and write requests from a host computer on the data in the storage. An in-storage compute controller may receive a predicate from the host computer to be applied to the input encoded data. A transcoder may include an index mapper to map an input dictionary to an output dictionary, with one entry in the input dictionary mapped to an entry in the output dictionary, and another entry in the input dictionary mapped to a “don't care” entry in the output dictionary.

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.

Abstract: According to one general aspect, a computing device may include a computing task memory configured to store at least one computing task. The computing task may be executed by a data node of a distributed computing system, with at least one data node further comprising an intelligent storage medium, wherein the intelligent storage medium comprises at least one controller processor, and a non-volatile memory. The computing device may include a mapping processor configured to: statically decide whether to assign the computing task to be executed by either one of the host processors of the data node or one of the controller processors of the intelligent storage medium based upon at least one rule that indicates whether a performance gain is expected, and assign, according to the static decision, the computing task to be executed by the determined processor.

Abstract: An adaptive mechanism may include a receiver, an Arithmetic Logic Unit (ALU) identifier, and an assignment module. The receiver may receive tasks representing iterations of inexact algorithms. Each task may have a corresponding iteration power level. The ALU identifier may identify a set of available ALUs. Each ALU may have a corresponding ALU power level. The assignment module may assign tasks to available ALUs to optimize a total ALU power used.
