An index file input line looks like:
<ID> <alpha> <beta> <incX> <incY> <source file> <author name>
The kernel will never be called with
beta == 1.0
(AXPY is called instead).
The kernel will never be called with
beta == 0.0
(CPSC is called instead).
The kernel will never be called with
alpha == 0.0
(SCAL is called instead).
For complex, if both vector strides are 1, and the imaginary components of alpha and beta are both zero, the real kernel is called with
2*N
.
