The new default behaviour should be more stable than before.\r\nUnfortunately testing everything is quite hard, because tests will not catch if a file was written in a background thread, or in a temporary location first. So before merging we should give this a thorough manual testing.\r\nAlso reviewing the diffs is a pain, because the logic was very complicated (and still is, although its simpler now). I found it easier to just look at the old state and the new state separately.\r\nSomewhat unrelated changes that occur in this pull request:\r\n- previously we supported writing in the background for file formats other than vtu and hdf5 (e.g. gnuplot). I found it easier and more readable to separate this into another branch of the if-loop and did not reimplement this feature. I guess that is fine, since nobody should use an ascii output for models so large that they require writing in a temporary storage and/or in a background thread.\r\n- previously we wrote .pvtu,. pvd and ,.visit files even for other output formats (except hdf5). Was this a glitch? They did not seem to work in Visit or Paraview anyway. I removed this behaviour.\r\n"},"comment":{"url":"https://api.github.com/repos/geodynamics/aspect/issues/comments/184261968","html_url":"https://github.com/geodynamics/aspect/pull/752#issuecomment-184261968","issue_url":"https://api.github.com/repos/geodynamics/aspect/issues/752","id":184261968,"user":{"login":"bangerth","id":7504421,"avatar_url":"https://avatars.githubusercontent.com/u/7504421?v=3","gravatar_id":"","url":"https://api.github.com/users/bangerth","html_url":"https://github.com/bangerth","followers_url":"https://api.github.com/users/bangerth/followers","following_url":"https://api.github.com/users/bangerth/following{/other_user}","gists_url":"https://api.github.com/users/bangerth/gists{/gist_id}","starred_url":"https://api.github.com/users/bangerth/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/bangerth/subscriptions","organizations_url":"https://api.github.com/users/bangerth/orgs","repos_url":"https://api.github.com/users/bangerth/repos","events_url":"https://api.github.com/users/bangerth/events{/privacy}","received_events_url":"https://api.github.com/users/bangerth/received_events","type":"User","site_admin":false},"created_at":"2016-02-15T15:45:39Z","updated_at":"2016-02-15T15:45:39Z","body":"I suppose that a lot of smaller clusters only have NFS, and that people run a lot of jobs on them with 100 or 200 cores. For these, I don't think that the current strategy is inherently a bad idea."}}
