Inspector-executor Sparse BLAS Routines

The inspector-executor API for Sparse BLAS divides operations into two stages: analysis and execution. During the initial analysis stage, the API inspects the matrix sparsity pattern and applies matrix structure changes. In the execution stage, subsequent routine calls reuse this information in order to improve performance.

The inspector-executor API supports key Sparse BLAS operations for iterative sparse solvers:

  • Sparse matrix-vector multiplication
  • Sparse matrix-matrix multiplication with a sparse or dense result
  • Solution of triangular systems
  • Sparse matrix addition
