SERVER-21415 added an Linux Oplog Compare variant to the sys-perf project that compares the performance of standalone vs. single-node mongod with oplog. The tasks for this variant is sorted differently as the other variants because Evergreen sorted tasks in other variants by the dependency whereas here we do not have dependency amongst the tasks. To ensure a consistent view of the results across variants, we can force the same display order by putting in similar dependencies for this variant.
