Hi All Some time ago, I posted a question (message 704) to this list about Determinism/Non-Determinism in Executable UML, which Marc was kind enough to answer...
My quick stab at the question inserted below. I am hoping your question provokes some further discussion. ... I think the confusion may center around the...
The problem posed in question 704 <http://tech.groups.yahoo.com/group/executableuml/message/704> was Suppose you have a PIM expressed in Executable UML...
Hi Marc ... written, all 'send signal' actions occur at the end of the procedure's execution." You seem to be suggesting that the semantics of the Executable...
If by "suppose we made a rule", one means "suppose the modelers and architects on a given project together agree to make a rule for that project that said...",...
... I actually put that wording into the Wikipedia entry. I'm not sure what prompted me to use "deterministic system" vs "system", but the Wikipedia...
Hi Lee ... This is not true if the two objects are on different computers, and the signal and query mechanisms are implemented using different communication...
... What I meant was, if you use an architecture that ensures a strictly synchronous signaling mechanism on a single-threaded system (no side effects), then...
Yeah, we should all be contributing to this and related entries such as MDA, Domains, etc. I had been meaning to start an entry for Sally Shlaer as well....
Hi Lee ... Exactly. And if this is possible, the Wikipedia entry is wrong (or at least misleading). I would suggest that it be changed, to avoid trouble from...
... If ExecutableUML were truly deterministic it would no longer be useful for interacting with a physical world that was not in fact deterministic. I would...
Hi All Just to make my own point of view clear, and lest my position be seen as gratuitous pedantry: There are some languages that deal with concurrency but do...
On Thu, Oct 9, 2008 at 12:11 AM, Ashley at Metamaxim ... I would agree that it is misleading, perhaps even fundamentally so. Properly understood, any...
Hmmm... Somebody copied where a link would have sufficed. This is the actual problem that should be corrected. I posted as much to the discussion section of...
Someone's not clear on what's in which Domain. J From: executableuml@yahoogroups.com [mailto:executableuml@yahoogroups.com] On Behalf Of Lee Riemenschneider ...
... The TODO list in the discussion tab lists that examples need to be included. I haven't got around to adding any. Maybe a link to Leon's elevator model...
Hello, I red http://www.embedded.com/in_focus/embedded_systems/OEG20021115S0045 which is an article written by steven mellor and leon starr in 2001 (A method...
... I think the wording, that you quoted, is poorly written. Mellor and Starr had the intention to state that both behavioral code generation and translative...
... They are trying to compare a Rhapsody or Rose RT type environment to a xUML environment. If the performance of the former on the actual embedded target...
I have illustrated and explained what is pretty much already covered by Mellor-Balcer regarding Time and Synchronization along with some additional RT model...

Thanks, Marco! Yes, I do plan to put everything, elevator 2.1 included, up on google knol eventually. It is currently in the course I teach. New print ...
I've been meaning to post an entry for Sally on Wikipedia for some time now and, thanks to some useful data from Steve Mellor, I've got a start. Anyone with an...
Excellent article. As for citable documents, I recall that there were handouts at the early tutorials on Reecurive Design at the Embeded Systems Conference....
