Title:
Composition metaprogramming and component metadata
Paul H J Kelly

Abstract:
Performance optimisations very commonly arise from adapting components to their context of use - so optimisation tends to reduce reusability, clarity and long-term software value. Our attack on this problem is to automate the adaptation to context. To make this work in a scalable way, we need to support a marketplace of "domain-specific optimisation components" that encode knowledge specific to a particular application domain, component family or API. This talk reviews a couple of our current projects in this area.
