Subject [jira] [Commented] (FLINK-8431) Allow to specify # GPUs for TaskManager in Mesos

Dongwon Kim commented on FLINK-8431:
------------------------------------

[~eronwright] What I need to do next is to cope with the new Mesos components that are proposed
by FLIP-6. I found flink-1.5-SNAPSHOT has two other scripts, {{mesos-appmaster-flip6-job.sh}}
and  {{mesos-appmaster-flip6-session.sh}} besides {{mesos-appmaster.sh}}. I want to know how
it works by executing them but I cannot find any document. 

* Is further modification needed to cope with FLIP-6 components?
* Can you explain how to execute FLIP-6 components? I cannot find any document regarding {{mesos-appmaster-flip6-job.sh}}
and  {{mesos-appmaster-flip6-session.sh}}.
* When I execute {{mesos-appmaster-flip6-session.sh}}, a new framework appears in Mesos UI
but there's no hyperlink to the framework. Is this the dispatcher introduced in Flink-1.5?

> Mesos provides first-class support for Nvidia GPUs [1], but Flink does not exploit it
when scheduling TaskManagers. If Mesos agents are configured to isolate GPUs as shown in [2],
TaskManagers that do not specify to use GPUs cannot see GPUs at all.
> We, therefore, need to introduce a new configuration property named "mesos.resourcemanager.tasks.gpus"
to allow users to specify # of GPUs for each TaskManager process in Mesos.
