I wrote a script (Perl) that makes simultaneous execution of
multiple E+ runs easy. It doesn't break up an individual run as you allude,
but handles all the thorny logistical issues that result from E+'s use of
hard-coded filenames and such. We use it to distribute runs across a small
Linux cluster. I donated the script to the E+ folks but don't believe they've
done anything with it. Contact me if you're interested.

Why do "fill in" and "fill out" mean the
same thing?

Running at the same time.
Ah I see....
To run E+ from another folder and avoid simulation conflicts, you just need to
run it from in a separate folder.
1. The .ini file pointing to the root installation folder. like [program]
dir=C:\ENERGY~1\)
2. A idf file named "In.idf"
3. A EPW file names "In.epw"
Then while in the separate folder, run.
C:\EnergyPlusV4-0-0\energyplus.exe
The RunEplus makes sure old files are gone, changes the name of the weather and
idf files to the above.
I'm writing a small threaded ruby script to divide an annual simulation into
the number of cpus-cores to speed up the runtime and then eventually add up the
energy, find the peaks, and underheated hours, using the eso or the sql output.
I have an 8-core computer and want to take advantage of it. I'll post the first
part of it if anybody is interested.
