MatDenseHIPGetArray#

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

Synopsis#

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().
