SpMV on GPUs

This research has focused on optimizing sparse matrix representations (i.e. storage formats) for data-parallel accelerators (i.e. GPUs). In addition, it is shown that no sparse matrix representation is consistently superior, with the best representation being dependent on the matrix sparsity patterns. The research then uses machine learning techniques to automatically select the best sparse representation for a given matrix.
