Conclusions<br />
• multi-core works best under process memory <strong>isolation</strong>: each<br />
process owns disjoint memory. A good model (actor-like).<br />

• in general need ownership transfer – hardware cost of this is that<br />
of a copy.<br />
• good if ownership transfer is policed by a type system; syntactic<br />
markers give the compiler the right to optimise actual data<br />
transfer.<br />
• substructural <strong>types</strong> provide such a type system<br />
• might need loopholes/exceptions to the type system <strong>for</strong> real<br />
programs (most of the data is still protected).<br />
• Kilim is one solution (a sweet-spot).<br />
