Use multiple cores

[Yuri05]

Use multiple CPU cores for simulation and comparison
(maybe also possible for report creation?)

[msevestre]

• Comparison is almost instantaneous
• Report Creation: No. The creation of the tex code is also instantaneous. Compiling with miktex takes forever.
• Run simulation in //. Theoretically possible. We tried however and it did not work as expected. We had some issues with SimModel instantiated more than once (in population or PI calculation, we only have one instance that we use)

We could try to reproduce the issue with SimModel but this might not be worth our time

We had some issues with SimModel instantiated more than once

Do you have a reproducible example for this?

in population or PI calculation, we only have one instance that we use

I cannot follow. One SimModel Instance can run only sequentially, not parallel.

For my understanding, e.g. in a PI: N SimModel instances are created, 1 per simulation:

No no example. This was a long time ago and not worth investigating. Some issues with xml that could not be parsed when instantiating more than once. Again, because the batch tool was used internally only at the time, no big deal. It was also not based on snapshot and the PI stuff was not implemented. Maybe the issue is fixed

However the problem with // computing would be that the log info would be completely nonsensical. Right now it is sequential. I am not sure how anyone could understand a NON sequential log file..or what needs to be done to support sthg like that

@Yuri05 Do you want to look at that for 7.5.0?

[Yuri05]

yes
