Ask HN: Tools/infrastructure for running tests on multiple hosts simultaneously?

My workflow has me running tests, in an interactive and iterative way on up to 250 hosts at a time, with machines divided into one of a set of up to 6 roles (some may have multiple roles). I currently use GNU Parallel or Python Fabric depending on what I need to do but this requires writing a bunch of custom code for every set of tests I run. Is there anything else out there that could reduce the overhead of my approach?

I have some background in automation, python, and shell scripting - but I cant tell your exact pain points (other than you want to reduce some work). Maybe you can use some python (or some other language) scripting for generating your scripts , but having detailed knowledge of your scenario would be helpful to answer this.
