I discovered that it is still a bad idea to use an iterator from begin(row) to end(row) because end(row) jumps to the beginning of the next _relevant_ row. This is too bad on 10g unknowns. Thus, I removed the use of the iterators in the Trilinos sparse matrix and Trilinos sparsity pattern in favor of column_number.\r\n- When working with more than 5000 processors, the approach to use a nonlocal graph that is filled with a dummy on each processor (in order to guarantee some Epetra-internal layout switching) is too bad. On >7000 cores my computations often got completely stuck because the communication model by Trilinos seems to end up in a black hole. Sometimes my cluster complained which allowed me to find the bug.\r\n- parallel::distributed::Vector has been extended to the >4g case.\r\n- DoFHandler::distribute_mg_dofs had a bug in computing the index sets for locally owned level dofs. (Another PR will be opened during the next days with fixes to MGTransferPrebuilt.)","created_at":"2015-09-22T13:37:59Z","updated_at":"2015-09-22T14:55:40Z","closed_at":null,"merged_at":null,"merge_commit_sha":"1c4bb6627322224674f434adf8e05f46c5e7aefb","assignee":null,"milestone":null,"commits_url":"https://api.github.com/repos/dealii/dealii/pulls/1648/commits","review_comments_url":"https://api.github.com/repos/dealii/dealii/pulls/1648/comments","review_comment_url":"https://api.github.com/repos/dealii/dealii/pulls/comments{/number}","comments_url":"https://api.github.com/repos/dealii/dealii/issues/1648/comments","statuses_url":"https://api.github.com/repos/dealii/dealii/statuses/cdaf9caf4f8193fdd1368c62ca7299fab80a545c","head":{"label":"kronbichler:master","ref":"master","sha":"cdaf9caf4f8193fdd1368c62ca7299fab80a545c","user":{"login":"kronbichler","id":8276200,"avatar_url":"https://avatars.githubusercontent.com/u/8276200?v=3","gravatar_id":"","url":"https://api.github.com/users/kronbichler","html_url":"https://github.com/kronbichler","followers_url":"https://api.github.com/users/kronbichler/followers","following_url":"https://api.github.com/users/kronbichler/following{/other_user}","gists_url":"https://api.github.com/users/kronbichler/gists{/gist_id}","starred_url":"https://api.github.com/users/kronbichler/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/kronbichler/subscriptions","organizations_url":"https://api.github.com/users/kronbichler/orgs","repos_url":"https://api.github.com/users/kronbichler/repos","events_url":"https://api.github.com/users/kronbichler/events{/privacy}","received_events_url":"https://api.github.com/users/kronbichler/received_events","type":"User","site_admin":false},"repo":{"id":22549298,"name":"dealii","full_name":"kronbichler/dealii","owner":{"login":"kronbichler","id":8276200,"avatar_url":"https://avatars.githubusercontent.com/u/8276200?v=3","gravatar_id":"","url":"https://api.github.com/users/kronbichler","html_url":"https://github.com/kronbichler","followers_url":"https://api.github.com/users/kronbichler/followers","following_url":"https://api.github.com/users/kronbichler/following{/other_user}","gists_url":"https://api.github.com/users/kronbichler/gists{/gist_id}","starred_url":"https://api.github.com/users/kronbichler/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/kronbichler/subscriptions","organizations_url":"https://api.github.com/users/kronbichler/orgs","repos_url":"https://api.github.com/users/kronbichler/repos","events_url":"https://api.github.com/users/kronbichler/events{/privacy}","received_events_url":"https://api.github.com/users/kronbichler/received_events","type":"User","site_admin":false},"private":false,"html_url":"https://github.com/kronbichler/dealii","description":"The
