I need to run many do files concurrently. Using parallel and batcher packages, I have experimented with how many I can run. For whatever the reason, when the number of concurrent do files passes 20-24 range, they all get bugged down. The reason is NOT the cpu or RAM resources as I have plenty of those on the server I am running the do files. To overcome this I have installed a couple of Virtual Machines, but they get bugged down after 7-8 concurrent do files and they are much slower. So, with VMs I am not even getting 1/3 of the efficiency running the files as on running them on metal.

Before, starting to purchase more hardware for independent Stata installations, I figured I should explore if multiple Stata Installations on the same Operating System (of course in different locations on the same hard disk) would work. Before I try and possibly mess things up with my current set up, I thought I should ask to see if anybody could offer any insight.
