Re-run IDF and optimization


I am building a workflow to perform simulation optimization (currently I am using Octopus and OPOSSUM). The objective is to find out the minimum building energy consumption among all cases. However, as the simulation workflow is quite complex, the energy simulation takes time and hence I added “Re-run IDF” component to run several simulations at the same time. Can I still perform simulation optimization if I run several simulations in parallel? Please advise. Thanks.

Also, which plugin would you recommend for performing optimization?
