The IDF Editor allows you to do that if you're on windows. See the "Group" one.

Otherwise yes, use a python (or whatever language) script. I would recommend not bothering trying to rename the output files, instead use the -d, --output-directory ARG arg to set the output directory.

I started throwing a small example to get you started, and then I figured I might as well take another couple of minutes and turn it into a github repo so it can be used by others. So here's a crude way of running multiple simulations in parallel using python: just paste your own .epw and .idf into the root folder and python Run_EnergyPlus_Simulations_In_Parallel.py

Under the hood it uses multiprocessing to run simulations in parallel, and offloads to subprocess for runs.

The IDF Editor EP-Launch program allows you to do that if you're on windows. See the "Group" one."Group of Input Files" tab.

Note that if you really want filenames and not output directories to uniquely identify each sim, it'd be terribly easy to add this here on line 49: https://github.com/jmarrec/RunMultipleSimulationsInParallel/blob/0fcea0df1591cabb130a80eceb58e882078e669f/Run_EnergyPlus_Simulations_In_Parallel.py#L49

    shutil.copyfile(out_file, dest_file)

(of course, import shutil at top of file)
