Title: The Cog VM evolution
Type: Talk

Abstract: In 2008, the Squeak VM repository made by Dan Ingalls was
forked to give birth to the high-performance Cog VM, which is now the
default VM for multiple Smalltalk dialects such as Pharo, Squeak or
Cuis. Since the fork, new features and performance enhancements have
been introduced every year. This talk sums up all the main features
and main performance tweaks that were added to the Cog VM in
chronological order from 2008 to today. The focus is on the execution
engine: Memory management, interpretation, JIT compilation and FFI.
The talk lastly discusses the current work in-progress and short-term
future work.

Bio: Clément Béra is a PhD student working on virtual machines for
object oriented languages at Inria, Lille. He is now focusing on
runtime optimisations for the Cog virtual machine and its Smalltalk
clients.
