MatDenseHIPGetArray

Provides access to the HIP buffer inside a MATDENSEHIP matrix. The array must be restored with MatDenseHIPRestoreArray() when no longer needed.

Synopsis

PetscErrorCode MatDenseHIPGetArray(Mat A, PetscScalar **a)

Not Collective

Input Parameter

• A - the matrix

Output Parameter

• a - the GPU array in column major order

Note

Data can be copied to the GPU due to operations done on the CPU. If you need write only access, use MatDenseHIPGetArrayWrite(). For read-only access, use MatDenseHIPGetArrayRead().
