Schedule generator does not account for cost of intriniscs #10

Closed arporter closed 7 years ago

arporter commented 8 years ago

While working on #8 I've realised that the schedule generator quietly ignores the cost of any intrinsic operations - it considers only operators. This is a significant omission because the intrinsics that we do currently recognise (sin, cos, **) are computationally costly. In this issue we'll think about how we might remedy the situation.

Created schedule_intrinsics branch for this issue.

Currently the 'type' of an operator node is the string representing the operation itself, e.g. "+" for a node representing an addition. However, the 'type' of a node representing any intrinsic operation is just "intrinsic". Now that we need to include the cost of intrinsic operations this distinction feels awkward.
