The reference to the Blue Book made it quite obvious.

Thanks for the paper reference.

As for Gemstone I was aware of it. :)

So you mean ParcPlace Smalltalk-80 "supports multicore since the early days"?

I think those Smalltalk "processes" are run in the same OS thread and only use one core, so please explain what you mean.

Were you aware of Actra?

After re-reading the Process/ProcessScheduler chapter you are right, it explicitly mentions one VM per CPU.

So from that point I stand corrected, however I would say it was an implementation detail, as the ProcessScheduler could easily have other policies.

There's an enormous chasm between research experiments:

September 1988 "From Objects to Actors: Study of a Limited Symbiosis in Smalltalk-80"

:and well-understood techniques supported by all the programming tools.

Thanks for the paper.
