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