MatCUSPARSESetFormat

Sets the storage format of MATSEQCUSPARSE matrices for a particular operation. Only the MatMult() operation can use different GPU storage formats

Synopsis

#include "petscmat.h" 
PetscErrorCode MatCUSPARSESetFormat(Mat A, MatCUSPARSEFormatOperation op, MatCUSPARSEStorageFormat format)

Not Collective

Input Parameters

• A - Matrix of type MATSEQAIJCUSPARSE

• op - MatCUSPARSEFormatOperation. MATSEQAIJCUSPARSE matrices support MAT_CUSPARSE_MULT and MAT_CUSPARSE_ALL. MATMPIAIJCUSPARSE matrices support MAT_CUSPARSE_MULT_DIAG,MAT_CUSPARSE_MULT_OFFDIAG, and MAT_CUSPARSE_ALL.

• format - MatCUSPARSEStorageFormat (one of MAT_CUSPARSE_CSR, MAT_CUSPARSE_ELL, MAT_CUSPARSE_HYB.)
