VM composition and VM warmupZeit: Tue 17.5.2016, 16:00, 60 Minuten
Ort: Science Park 3, Room 218
ZusammenfassungProgramming languages are islands, each disconnected from the rest. We choose a language for a task and, for better or worse, stick with it. Communicating between programs written in different languages is such a slow, arduous, task that we avoid doing it whenever possible.
In this talk I will first show how language composition can lower, and even remove, the barriers between languages. We have pioneered new approaches to the two major challenges in language composition: editing and running composed programs. Using our novel editor 'Eco', users can write source files that contain fragments of multiple languages. We then run multi-language programs using composed meta-tracing VMs. Our preliminary results suggest that performance of composed programs is often competitive with traditional mono-language VMs.
I will then show ongoing research into understanding VM warmup. Our research suggests that the classical model of VM warmup may no longer reflect VM performance in the real world.
