by _jeff.science@gmail.com_ on 2013-02-13 20:03:36 -0600**\n\n___\nHydra seems to have magic support for PBS and other common schedulers such that mpiexec automagically does the right thing without any arguments.  I don't believe that this exists for the Cobalt scheduler.\n\nWe have an ALCF user running on Eureka, which is a traditional cluster that runs Cobalt, who struggled to get the procs per node right, or at least wasn't sure what would happen by default.  He eventually just set \"-machinefile $COBALT_NODEFILE\"  and everything was fine (he wanted 1 ppn).\n\nI wonder if it is possible to develop support for Cobalt within Hydra.  If this is a lot of work, it probably isn't worth it, but I wonder if it is as simple as telling Hydra to query COBALT_NODEFILE when it is asserted to be in the environment (i.e. because the user passes --with-cobalt to Hydra's configure).\n\nI'm not sure this request is perfectly well-defined but I assume that Pavan will be able to figure out what I mean and tell me whether or not this request is stupid or not worth the effort.\n\nPS Why is there no component in the Trac drop-down for Hydra?  I thought it was designed to be semi-standalone."},"comment":{"url":"https://api.github.com/repos/raffenet/mpich-migrate-test/issues/comments/237334715","html_url":"https://github.com/raffenet/mpich-migrate-test/issues/1793#issuecomment-237334715","issue_url":"https://api.github.com/repos/raffenet/mpich-migrate-test/issues/1793","id":237334715,"user":{"login":"raffenet","id":1410792,"avatar_url":"https://avatars.githubusercontent.com/u/1410792?v=3","gravatar_id":"","url":"https://api.github.com/users/raffenet","html_url":"https://github.com/raffenet","followers_url":"https://api.github.com/users/raffenet/followers","following_url":"https://api.github.com/users/raffenet/following{/other_user}","gists_url":"https://api.github.com/users/raffenet/gists{/gist_id}","starred_url":"https://api.github.com/users/raffenet/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/raffenet/subscriptions","organizations_url":"https://api.github.com/users/raffenet/orgs","repos_url":"https://api.github.com/users/raffenet/repos","events_url":"https://api.github.com/users/raffenet/events{/privacy}","received_events_url":"https://api.github.com/users/raffenet/received_events","type":"User","site_admin":false},"created_at":"2016-08-03T18:52:19Z","updated_at":"2016-08-03T18:52:19Z","body":"**Originally by _davidjgoodell@gmail.com_ on 2013-02-14 11:27:01 -0600**\n\n___\nI just added a \"hydra\" component for you."}}
