Because the performance of sparse matrix computations depends on its representation format [3], many researchers proposed various formats to store and represent these matrices [4–16, 32]. For example, Fig. 1 illustrates the performance of SpMV with nd24k input matrix using different formats. As...

We present a matrix language compiler CMC which translates annotated MATLAB scripts into Fortran 90 programs. Distinguishing features of CMC include its applicability to programs with sparse matrix computations and its capability of source-level optimization in MATLAB language. Different from other existing...

Similarity matrix constructionSparse matrix formatParallel code optimizationSpectral clustering has many fundamental advantages overk-means clustering, but comes at much higher time complexity and memory requirements mainly due to similarity matrix construction and eigenvectors computation. Thus, spectral ...
An apparatus to facilitate matrix processing is disclosed. The apparatus comprises a matrix accelerator to receive input matrix data, transform the input matrix data into a plurality of sub-blocks, examine a first block of the sub-blocks to determine whether the first block comprises sparse data,...
