  • DD2 (pyopencl.Buffer [out]) – Buffer object that contains DD2.
  • offDD2 (int [in]) – Offset to DD2 in DD2 buffer object. Counted in elements.
  • DX1 (pyopencl.Buffer [out]) – Buffer object that contains DX1.
  • offDX1 (int [in]) – Offset to DX1 in DX1 buffer object. Counted in elements.
  • DY1 (pyopencl.Buffer [in]) – Buffer object that contains DY1.
  • offDY1 (int [in]) – Offset to DY1 in DY1 buffer object. Counted in elements.
  • DPARAM (pyopencl.Buffer [out]) – Buffer object that contains DPARAM array of minimum length 5 DPARAM(0) = DFLAG DPARAM(1) = DH11 DPARAM(2) = DH21 DPARAM(3) = DH12 DPARAM(4) = DH22.
  • offDparam (int [in]) – Offset to DPARAM in DPARAM buffer object. Counted in elements.
  • commandQueues (pyopencl.CommandQueue [in]) – OpenCL command queues. A list, tuple, or single instance of pyopencl.CommandQueue. Must not be None.
  • eventWaitList (pyopencl.Event [in]) – Event wait list. A list, tuple, or single instance of pyopencl.Event. May be None.
Returns:

A tuple of pyopencl.Event instances, one for each commandQueue supplied.
