This way, users can try most popular online scheduling algorithms: FCFS, EAST/Hybrid/Conservative backfill. \r\n\r\nI have to believe all of the algorithms is already in the code, but it is currently statically determined [here]( https://github.com/flux-framework/flux-sched/blob/master/sched/sched_backfill.c#L44). \r\n\r\nHow about we devise some ways to pass \"backfill_depth=K\" where K can vary from 1 to unlimited. If it is set to 1, sched will do EAST backfill. If it is set to unlimited, the algorithm becomes conservative backfill. If K is set to be some number, it becomes hybrid. \r\n\r\nI was thinking to pass that as a new option to sched load. But then, if there is a way to pass a option to sched.backfill load, this would even be better.\r\n\r\nThoughts?"},"comment":{"url":"https://api.github.com/repos/flux-framework/flux-sched/issues/comments/224459719","html_url":"https://github.com/flux-framework/flux-sched/issues/159#issuecomment-224459719","issue_url":"https://api.github.com/repos/flux-framework/flux-sched/issues/159","id":224459719,"user":{"login":"dongahn","id":862123,"avatar_url":"https://avatars.githubusercontent.com/u/862123?v=3","gravatar_id":"","url":"https://api.github.com/users/dongahn","html_url":"https://github.com/dongahn","followers_url":"https://api.github.com/users/dongahn/followers","following_url":"https://api.github.com/users/dongahn/following{/other_user}","gists_url":"https://api.github.com/users/dongahn/gists{/gist_id}","starred_url":"https://api.github.com/users/dongahn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/dongahn/subscriptions","organizations_url":"https://api.github.com/users/dongahn/orgs","repos_url":"https://api.github.com/users/dongahn/repos","events_url":"https://api.github.com/users/dongahn/events{/privacy}","received_events_url":"https://api.github.com/users/dongahn/received_events","type":"User","site_admin":false},"created_at":"2016-06-08T01:08:51Z","updated_at":"2016-06-08T01:08:51Z","body":"@SteVwonder: BTW, do you have an idea as to how we can test correctness of various scheduling algorithms for CTS-1 testing?
