Class EstimatorBitsetMM

  • public class EstimatorBitsetMM
    extends SparsityEstimator
    This estimator implements a naive but rather common approach of boolean matrix multiplies which allows to infer the exact non-zero structure and thus is also useful for sparse result preallocation. For example, the following paper indicates that this approach is used for sparse spGEMM in NVIDIA cuSPARSE and Intel MKL: Weifeng Liu and Brian Vinter. An Efficient GPU General Sparse Matrix-Matrix Multiplication for Irregular Data. In IPDPS, pages 370–381, 2014.
