indicates the operation of CUSPARSE (GPU) matrices whose operation should use a particular storage format. Requires the txpetscgpu package to use. Configure with --download-txpetscgpu to build/install petsc with the txpetscgpu library.

Synopsis

typedef enum {MAT_CUSPARSE_MULT_DIAG, MAT_CUSPARSE_MULT_OFFDIAG, MAT_CUSPARSE_MULT, MAT_CUSPARSE_SOLVE, MAT_CUSPARSE_ALL} MatCUSPARSEFormatOperation;
Not Collective

MAT_CUSPARSE_MULT_DIAG - sets the storage format for the diagonal matrix in the parallel MatMult
MAT_CUSPARSE_MULT_OFFDIAG - sets the storage format for the offdiagonal matrix in the parallel MatMult
MAT_CUSPARSE_MULT - sets the storage format for the entire matrix in the serial (single GPU) MatMult
MAT_CUSPARSE_SOLVE - sets the storage format for the triangular factors in the serial (single GPU) MatSolve
MAT_CUSPARSE_ALL - sets the storage format for all CUSPARSE (GPU) matrices
