Attendance was good, especially given the very short notice given for
the meeting. Again I apologize, I'd recently returned from Asia, and
several of the people who wanted to attend were leaving the US at the
end of that week.
Emmanuel Bouyer gave a very nice presentation on concurrent processing
and Eiffel. Emmanuel began with a discussion of the limitations the
current SCOOP specification. He explained in particular why SCOOP could
not be used to implement Eiflex. He then presented an overview of the
Eiflex distributed object framework. The Eiflex framework provides a
reliable platform-independent, multithreaded client/server architecture
and is the basis of the Chicago Board of Trade's PRICE system.
Emmanuel then ran a "Dining Philosophers" demonstration that involved a
GUI client and two server processes. One im****tant aspect of the demo
was the fault tolerance. You can kill the servers, but when they are
restarted they will carry on where they left off, having preserved
their state. Eiflex is highly also scalable. At CBOT, Windows clients
connect to over one hundred Solaris servers, with each server running
two hundred or more threads.
After Emmanuel's presentation, the gatherers congratulated Eric and
Karine on their wedding, spent a little time surfing the Team Eiffel
blog for interesting tidbits, and talked about what is going on with
the various Open Source Eiffel projects around the world.
The next meeting will be held in September (too many people are
traveling in August). I promise to give earlier advance notice.
Future meetings will be every other month, with a special effort to
overlap with visits by Eric and Karine.
Emmanuel's presentations were based on those made by Gordon Jones
(Emmanuel's partner at Eiflex) for a conference at York University in
the UK.
