Instead of relying on our own atomics, we should leverage what the compiler, or the OS, is supporting. This patch change the default behavior for builds on OSX or with a compiler supporting gcc-type atomic builtins.\r\n\r\nThis is a replacement for the now defunct #288.\r\n\r\n@goodell and @hjelmn please review."},"comment":{"url":"https://api.github.com/repos/open-mpi/ompi/issues/comments/110642224","html_url":"https://github.com/open-mpi/ompi/pull/633#issuecomment-110642224","issue_url":"https://api.github.com/repos/open-mpi/ompi/issues/633","id":110642224,"user":{"login":"mellanox-github","id":9459943,"avatar_url":"https://avatars.githubusercontent.com/u/9459943?v=3","gravatar_id":"","url":"https://api.github.com/users/mellanox-github","html_url":"https://github.com/mellanox-github","followers_url":"https://api.github.com/users/mellanox-github/followers","following_url":"https://api.github.com/users/mellanox-github/following{/other_user}","gists_url":"https://api.github.com/users/mellanox-github/gists{/gist_id}","starred_url":"https://api.github.com/users/mellanox-github/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mellanox-github/subscriptions","organizations_url":"https://api.github.com/users/mellanox-github/orgs","repos_url":"https://api.github.com/users/mellanox-github/repos","events_url":"https://api.github.com/users/mellanox-github/events{/privacy}","received_events_url":"https://api.github.com/users/mellanox-github/received_events","type":"User","site_admin":false},"created_at":"2015-06-10T07:57:46Z","updated_at":"2015-06-10T07:57:46Z","body":"\nRefer to this link for build results (access rights to CI server needed): \nhttp://bgate.mellanox.com/job/gh-ompi-master-pr/617/\n"}}
