During the tests with htop the loss of power of the threads is significant and we can not keep the fluency between the threads. \r\n\r\n\r\nThe code shows the solution to this problem. Summary: this is the  fall back to the previous version of the code + MKLDNN flag."},"comment":{"url":"https://api.github.com/repos/PaddlePaddle/Paddle/issues/comments/397741756","html_url":"https://github.com/PaddlePaddle/Paddle/pull/11481#issuecomment-397741756","issue_url":"https://api.github.com/repos/PaddlePaddle/Paddle/issues/11481","id":397741756,"node_id":"MDEyOklzc3VlQ29tbWVudDM5Nzc0MTc1Ng==","user":{"login":"mozga-intel","id":36698412,"node_id":"MDQ6VXNlcjM2Njk4NDEy","avatar_url":"https://avatars0.githubusercontent.com/u/36698412?v=4","gravatar_id":"","url":"https://api.github.com/users/mozga-intel","html_url":"https://github.com/mozga-intel","followers_url":"https://api.github.com/users/mozga-intel/followers","following_url":"https://api.github.com/users/mozga-intel/following{/other_user}","gists_url":"https://api.github.com/users/mozga-intel/gists{/gist_id}","starred_url":"https://api.github.com/users/mozga-intel/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mozga-intel/subscriptions","organizations_url":"https://api.github.com/users/mozga-intel/orgs","repos_url":"https://api.github.com/users/mozga-intel/repos","events_url":"https://api.github.com/users/mozga-intel/events{/privacy}","received_events_url":"https://api.github.com/users/mozga-intel/received_events","type":"User","site_admin":false},"created_at":"2018-06-15T21:03:28Z","updated_at":"2018-06-15T21:03:28Z","author_association":"CONTRIBUTOR","body":"@tensor-tang Thank you for your quickly answer.\r\n\r\nI stay in touch with you."}}
