If people are willing to spend some time discussing this at GGF17, I would take a stab at rendering both BES and ESI using the SAGA model, and send it out before we get to Tokyo. -- Chris On 20/4/06 15:28, "Ian Foster" <foster@mcs.anl.gov> wrote:
that would be great

And the SAGA model can be used (maybe with some refinement) to model all three of ESI, BES and SAGA state diagrams...
You can probably guess which model I would vote for. :-)

It's certainly very desirable that we end up with a single common model!
We have the ESI model, that reflects experience in GRAM and Unicore; the BES model; and the SAGA model.

independent of BES. Can you explain? Ian.
Ah, but we don't :-) SAGA has a very simple state model (new, running, done, failed, unknown). However, the states have 'substates', which can be queried, and expose the complete BES state model.
The simple model above only exposes those states which can be changed with SAGA calls. As saga calls get added, e.g. for hold, more stated might get exposed on that level.
Please have a look at http://www-unix.gridforum.org/mail_archive/saga-rg/2006/02/png00005.png I hope that state diagram makes that clearer. I am not sure if it is in sync with the current BES states.
Another post to exactly that topic is at http://www-unix.gridforum.org/mail_archive/saga-rg/2006/02/msg00131.html
Cheers, Andre.

Hi all, Per Marvin's comments ... Here is a pointer to the proposal for modelling job states that I made to the SAGA group last February.
