Notes for CPSC

  1. Performs $ y \leftarrow \alpha x $
  2. An index file input line looks like:
    <ID> <alpha> <incX> <incY> <source file> <author name>
  3. Never called with $\alpha$ of zero (SET is called instead).
  4. Never called with $\alpha$ of one (COPY is called instead).
  5. For complex, if both vector strides are 1, and the imaginary component of $\alpha$ is zero, the real kernel is called with 2*N.
  6. incX arbitrary incY=1 is interesting since it represents copying to contiguous storage.
