I'm too, interested in this topic. I've found some old presentation from OM developer on Google, but no concrete use case/example so far... How could we utilize multi core for Openmodelica simulation? is it possible?

As far as I am concerned, for now the only automatic parallelization option is to use HPCOM. Here there is a link to a tutorial:

I have tried this example, but when running the .mos file, I only get the results file as in the OMEdit usual simulation and the task graphs (ODE, DAE, schedule and so on) but I don't know how to get the serial and parallel costs.

Which kind of models do you want to parallelize?
