This switch was motivated by the fact that now\r\non some platforms, its possible for multiple MTLs to\r\nbe initializable, but only one MTL should be selected.\r\n\r\nIn addition, there is a complication with the PSM and\r\nIFO (with PSM provider) MTLs owing to the fact that\r\nthey cannot both intialize the underlying PSM context,\r\ni.e. only one call to psm_init is allowed per process.\r\n\r\nThe mxm component has not been compiled as the author\r\ndoesn't currently have access to a system with a recent\r\nenough mxm installed to allow for a compile.\r\n\r\nThe portals4, ofi, and psm components have been checked\r\nfor compilation.  The ofi and psm components have been\r\nchecked for runtime correctness on a intel/qlogic system\r\nwith up to date PSM installed.\r\n\r\nBunch of impacted MTL authors:\r\n\r\n@bureddy  @regrant @adrianreber \r\n\r\nFixes open-mpi/ompi#735\r\n\r\nSigned-off-by: Howard Pritchard <howardp@lanl.gov>"},"comment":{"url":"https://api.github.com/repos/open-mpi/ompi-release/issues/comments/125245915","html_url":"https://github.com/open-mpi/ompi-release/pull/409#issuecomment-125245915","issue_url":"https://api.github.com/repos/open-mpi/ompi-release/issues/409","id":125245915,"user":{"login":"yburette","id":8826543,"avatar_url":"https://avatars.githubusercontent.com/u/8826543?v=3","gravatar_id":"","url":"https://api.github.com/users/yburette","html_url":"https://github.com/yburette","followers_url":"https://api.github.com/users/yburette/followers","following_url":"https://api.github.com/users/yburette/following{/other_user}","gists_url":"https://api.github.com/users/yburette/gists{/gist_id}","starred_url":"https://api.github.com/users/yburette/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/yburette/subscriptions","organizations_url":"https://api.github.com/users/yburette/orgs","repos_url":"https://api.github.com/users/yburette/repos","events_url":"https://api.github.com/users/yburette/events{/privacy}","received_events_url":"https://api.github.com/users/yburette/received_events","type":"User","site_admin":false},"created_at":"2015-07-27T15:31:33Z","updated_at":"2015-07-27T15:31:33Z","body":"I'm working with this PR.\r\n\r\nWhen I add --mca mtl ofi (but not --mca pml cm), I get the following error:\r\n```\r\n--------------------------------------------------------------------------\r\nWARNING: There are more than one active ports on host 'f011', but the\r\ndefault subnet GID prefix was detected on more than one of these\r\nports.
