Rados suites are typically scheduled with these parameters:
./teuthology/virtualenv/bin/teuthology-suite -v -m smithi -c <branch name> -s rados --subset 111/120000 -p <priority>
This will generate around 300 jobs from the rados suite. Choose a priority accordingly (100 is usually good for 300+ job runs).
