Running Plecs on multi-core machine

0 votes
Hi !

I tried to run a simulation on a multicore linux machine but I noticed that the simulation's speed is quite the same. (just little bit higher)

Is there a way to increase the speed with this type of machine? A different license? Something to change in Plecs's parameter?

Thank you.

Currently, PLECS uses just a single core for computing a PLECS model. A second core (if available) is only employed for the GUI, e.g. for preparing the graphical output in PLECS scopes. This is why you cannot speed up the simulation of a single PLECS model by having more than two cores.

However, if you run multiple simulations simultaneously, they will automatically distributed to different cores.

Thank you so much!
Are there other ways to speed up the simulation?

I wrote a workarund in python to do that, it generate more variants of the same simulation and then run parallel with gui automatization

 you can find on my github
