Distributed Testing

I wish to run tests with more than 1000 users and my machines aren’t powerful enough to handle that kind of traffic. Currently I have to manually ssh into each machine and trigger the tests. I was wondering if Gatling provided a way to do so internally. I’ve read through a lot of the posts on this forum and I believe that distributed testing was supposed to be implemented by 2013. Has the support been added yet? If so, where can I find the documentation to do the same?
