[EnergyPlus_Support] Re: Multiple instances of EnergyPlus Running at the same time.
Hey Todd,
I uploaded a script in Ruby recently that splits up and runs an annual simulation. I incorporated what I think is a good approach on running multiple simulations, but would like to see yours to see if I am missing anything.
I think this forum should promote the use of scripts (Perl, Ruby, or otherwise) to extend the usability of E+. Could we create a new folder under the Files folder for such things?
I'm currently working on a few other scripts, one is to automatically create plant loops using a simplified input approach, like writing the HVAC LOOP like a grocery list and have the script deal with creating the nodes and connections. Without dealing with a fancy GUI. Hopefully I can have something working for simple systems by the end of the month.

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.

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.
