[Dune-devel] Explicit template instantiation

[Christian Engwer]

Hi Simon,

we have made good experience wir explicit instantiations for several application modules. Still there is one aspect I'm concerned about.

We only used it for coarse grained interfaces. How is the situation for fine grained interfaces like most dune-grid interfaces? We rely on inlining for reducing the overhead. How does inlining play with explicit instantiation?

In particular for yaspgrid we might experience a significant performance penalty. Do you have some tests?

Ciao
Christian
