Subject [jira] [Commented] (YARN-6852) [YARN-6223] Native code changes to support isolate GPU devices by using CGroups
Date Fri, 08 Sep 2017 08:58:01 GMT

    [ https://issues.apache.org/jira/browse/YARN-6852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16158338#comment-16158338

Zhankun Tang commented on YARN-6852:

[~wangda], Thanks for the patch. I'd like to update FPGA related patch based on current progress.

But it seems the c-e.cfg format and device isolation logic is almost same for GPU and FPGA.
Since the c-e binary is mainly providing cgroups isolation API to the above device resource
handler by executing below privileged command:
container-executor gpu --excluded_gpus=0,1 --container_id=container_x_y_z
Is it valuable that we make a general module so that we don't need to implement one native
module for each hardware accelerator?
container-executor hw-acc --container_id=container_x_y_z --include_hw-acc=0,1 or --excluded_hw-acc=0,1
