Subject [jira] [Commented] (YARN-6852) [YARN-6223] Native code changes to support isolate GPU devices by using CGroups
Date Tue, 12 Sep 2017 01:15:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-6852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16162318#comment-16162318
] 

Zhankun Tang commented on YARN-6852:
------------------------------------

[~wangda], agree with you. I'll refactor both native and java side code.
But still a concern is that how can we determine which resource should be treated as first-class
citizen? I'm afraid a flexible way with minimal code changes to enable more hardware accelerator
resource type is needed? For instance, just a .so for every device module?
