Abstract: A storage manager may be used to perform a refinement operation on a coding matrix as part of a coding operation (e.g., an encoding operation or a decoding operation) in a storage system, such as an object-redundant storage system. The refinement operation may include identifying a plurality of computations to be performed as part of the coding operation, where the plurality of computations have common terms and operations. The refinement operation may include refining a coding matrix associated with the coding operation based on the identified computations and precomputing the identified computations. The precomputed computations may be used instead of performing the computations when performing the coding operation.

Abstract: A storage manager may be used to perform a coding operation (e.g., an encoding operation or a decoding operation) on a data object using a refined version of a coding matrix in a storage system, such as an object-redundant storage system. The coding operation may include identifying a coding matrix for the data object and retrieving a refined version of the identified coding matrix from a data store of pre-refined coding matrices. The refined version of the coding matrix may identify two or more computations to be performed as part of the coding operation, where the two or more computations have common terms and operations. The coding operation may include determining one or more precomputed results of the two or more identified computations. The precomputed results may be used instead of performing the computations when performing the coding operation.
