  • X (pyopencl.Buffer [in]) – Buffer object storing vector X.
  • offx (int [in]) – Offset of first element of vector X in buffer object. Counted in elements.
  • incx (int [in]) – Increment for the elements of X. Must not be zero.
  • scratchBuff (pyopencl.Buffer [in]) – Temporary cl_mem scratch buffer object of minimum size N.

  • 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.
