Hey,
While we're at it. I'm implementing reductions, now.
There are two options here :
template<class OP, class VectorType> reduce(VectorType const & v) {
return scalar_expression<VectorType, OP, reduce_type>(v, OP());
}
or
template<class OP, class VectorType> reduce(VectorType const & v) {
return scalar_expression<VectorType, VectorType, reduce_type<OP> >(v,v);
}
the first one is scheduler-friendly, but the second one is more
meta-programming friendly. I'm really confused here, any advice on which
one to choose? I would prefer the first one, since handling the second one
in the scheduler would clearly be a pain, considering that I don't want to
introduce REDUCE_ADD, REDUCE_MAX, etc..., but just a single REDUCE,
operator, and reuse the existing ones. I think several other similar cases
will arise, such as three arguments function, where it is preferable to
create the appropriate tree structure directly from the function call. Am I
right?
