[jira] [Resolved] (YARN-8888) Support device topology scheduling

     [ https://issues.apache.org/jira/browse/YARN-8888?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Zhankun Tang resolved YARN-8888.
--------------------------------
    Resolution: Won't Fix

Resolve it due to the GPU topology algorithm is better implemented in the plugin for now.

Abstraction for all device topology is too early now.

See YARN-8821 for GPU topology scheduling.
