Notes for COPY

  1. Performs $ y \leftarrow x $
  2. An index file input line looks like:
    <ID> <incX> <incY> <source file> <author name>
  3. For complex with both vector strides 1, the real kernel is called with 2*N.
  4. incX arbitrary incY=1 is interesting since it represents copying to contiguous storage.
