Each node is equipped with GPU. I compiled CaffeOnSpark with GPU mode and also changed configuration in the solver. However, while I followed tutorial on GetStarted_local and deployed mnist training on multiple nodes (standalone mode), the computation was carried out by CPU instead of GPU. On the contrary, training on single node through CaffeOnSpark used GPU successfully. \r\n\r\nSo my question is how to switch on GPU mode on multiple nodes.\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/yahoo/CaffeOnSpark/issues/comments/232724628","html_url":"https://github.com/yahoo/CaffeOnSpark/issues/109#issuecomment-232724628","issue_url":"https://api.github.com/repos/yahoo/CaffeOnSpark/issues/109","id":232724628,"user":{"login":"GnosisYu","id":16881130,"avatar_url":"https://avatars.githubusercontent.com/u/16881130?v=3","gravatar_id":"","url":"https://api.github.com/users/GnosisYu","html_url":"https://github.com/GnosisYu","followers_url":"https://api.github.com/users/GnosisYu/followers","following_url":"https://api.github.com/users/GnosisYu/following{/other_user}","gists_url":"https://api.github.com/users/GnosisYu/gists{/gist_id}","starred_url":"https://api.github.com/users/GnosisYu/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/GnosisYu/subscriptions","organizations_url":"https://api.github.com/users/GnosisYu/orgs","repos_url":"https://api.github.com/users/GnosisYu/repos","events_url":"https://api.github.com/users/GnosisYu/events{/privacy}","received_events_url":"https://api.github.com/users/GnosisYu/received_events","type":"User","site_admin":false},"created_at":"2016-07-14T16:52:13Z","updated_at":"2016-07-14T16:52:13Z","body":"@guchensmile , my case is similar to yours. Do you check the utility of CPU? I think your training also used the GPU instead of CPU."}}
