The workflows of `trackingPhase1PU70` are replaced with workflows of the previous seeding (`trackingPhase1QuadProp`, suggestions for better name are welcome) to be kept as a reference for some time. Full cleanup of `trackingPhase1PU70` will come later (after the pre2 dust settles).\r\n\r\nHere are MTV plots for 1000 ttbar+35PU events in 900pre1 (using 810pre16 DIGI-RAW as an input)\r\nhttps://mkortela.web.cern.ch/mkortela/tracking/validation/CMSSW_9_0_0_pre1_caseeding/\r\n\r\nTiming decreases by ~5 % for the full trackingOnly reco job (becomes ~10 % when excluding most expensive other-than-iterative-tracking modules, mostly validation).\r\n\r\nThe previous seeding is kept workflows 10024.[45] (full/trackingOnly), so there should be no changes between old 10024.[01] and new 10024.[45].\r\n\r\nTo minimize merge conflicts the developments are based on @ebrondol's #16858 (in the hope of getting this in pre2).\r\n\r\nTested in CMSSW_9_0_X_2016-11-30-2300. No changes expected for phase0, phase1 changes are described above, and for phase2 there are changes because of #16858 (but no changes on top of that).\r\n\r\n@rovere @VinInn @felicepantaleo @ebrondol @mtosi "},"comment":{"url":"https://api.github.com/repos/cms-sw/cmssw/issues/comments/265940055","html_url":"https://github.com/cms-sw/cmssw/pull/16911#issuecomment-265940055","issue_url":"https://api.github.com/repos/cms-sw/cmssw/issues/16911","id":265940055,"user":{"login":"slava77","id":4676718,"avatar_url":"https://avatars.githubusercontent.com/u/4676718?v=3","gravatar_id":"","url":"https://api.github.com/users/slava77","html_url":"https://github.com/slava77","followers_url":"https://api.github.com/users/slava77/followers","following_url":"https://api.github.com/users/slava77/following{/other_user}","gists_url":"https://api.github.com/users/slava77/gists{/gist_id}","starred_url":"https://api.github.com/users/slava77/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/slava77/subscriptions","organizations_url":"https://api.github.com/users/slava77/orgs","repos_url":"https://api.github.com/users/slava77/repos","events_url":"https://api.github.com/users/slava77/events{/privacy}","received_events_url":"https://api.github.com/users/slava77/received_events","type":"User","site_admin":false},"created_at":"2016-12-09T05:57:10Z","updated_at":"2016-12-09T05:57:10Z","body":"if #16885 is merged on Friday, this will likely need a rebase\r\n"}}
