Abstract
Systems, methods and articles of manufacture are disclosed for transposing array data on a SIMD multi-core processor architecture. A matrix in a SIMD format may be received. The matrix may comprise a SIMD conversion of a matrix M in a conventional data format. A mapping may be defined from each element of the matrix to an element of a SIMD conversion of a transpose of matrix M. A SIMD-transposed matrix T may be generated based on matrix M and the defined mapping. A row-wise algorithm may be applied to T, without modification, to operate on columns of matrix M.
