hello everybody
I tried the method christophe le page proposed to investigate the computer time. however, i really don't understand how to use this interface. i mean the result looks like that (see attached file)
but what does that mean? and how to use it?
by the way the address for cincom visulworks is:

christophe LE PAGE <le_page@cirad.fr> a écrit :
Hmmmmm...
I’m quite sure that displaying the spatial grid window is VERY time-consuming, so for long and big simulations, it has to be closed.
As for the "simulation panel control" window, even if the current time step is redisplayed at each time step, I would be very surprised that this is causing the major pb you are mentionning.
But bur all the other Cormas GUI windows, fixed, I really don’t believe they can consume time during a simulation run.
What about probes, especially if you save them in a local file?
By the way, here is one way to investigate more deeply the distribution of the computing time used during one time step of your cormas model:
1. Load the parcel "AT Profiling" from VisualWorks main menu
2. Select “Tools -> Advanced -> Profiles -> Time” from VisualWorks main menu: it opens a code editor window called "profile execution time". Read the explanations and do the 3 tests to understand how this tool operates
3. Initialize your cormas model
4. In the "profile execution time" window, enter, select then evaluate the code below:
|c|
c := CormasNS.Kernel.Cormas allInstances first.
self profile: [c runStepByStep]
Bonne traque!
Amicalement,
Clp
