I introduced them thinking they were on topic, as general ideas to
maybe discuss in the talk. Or rather, to suggest discussing facts
about them in the talk.

Anwyay, some googling found a couple of interesting papers on
(dynamic) auto-parallelization, which are for Java.

are already not satisfactory, as pointed out by Guillem, but the 1st
paper seem to suggest that a JIT can better tune the introduced
Anyway, this seems still research and not production-level technology.
Is the latter available?

Maciej, I first want to apologize if my mail was not indeed useful,
and if I seemed to use pypy-dev as a forum.
But I was trying to discuss the topic of the conference appearance,
given that the topics (of the talk itself) are probably going to be
"Ideas for a JIT for numerical computing in Python" and "Is/Will be
Python better than alternatives, as of today/in the future?". The
"future" part is where all the "buzzwords" came from, even if more
experience could have detailed some of them. And I did want to provide
an overview, so that one can then focus on specific points.
Given the interest and resource on HPC computing, implementing in a
JIT optimizations for static compilers which are suited to HPC could
be useful and could find enough resources, if the optimizations are
worth their cost, and given somebody willing to solve the formidable
challenges I expect of this idea.
