MatDenseHIPGetArrayRead#
Provides read-only access to the HIP buffer inside a dense matrix. The array must be restored with MatDenseHIPRestoreArrayRead() when no longer needed.
Synopsis#
#include "petscmat.h"
PetscErrorCode MatDenseHIPGetArrayRead(Mat A, const PetscScalar **a)
Not Collective
Input Parameters#
A - the matrix
Output Parameters
array - the GPU array in column major order
Notes#
Data can be copied to the GPU due to operations done on the CPU. If you need write only access, use MatDenseHIPGetArrayWrite().
