I have 5 test suites which are independent of each other. 
I have to run it against the same environment. Most of my test suites consist of API calls.
The test cases inside the suites should run in sequence as they are dependent on each other.
Is there any way we can run all the test suites in parallel via the pybot command?
When the tests are completely stand-alone and can run completely parallel I have had some success with just writing an execution script that iterates through all the IP addresses of the units on which I would want to run a test in parallel and then calling the test with that IP address as an argument.  I also tell it to only create the output.xml files, naming them based on the hostname or IP address, and then the scrip does post-processing with rebot which creates an aggregated report with all the units.
