Eron Wright commented on FLINK-8431:
-------------------------------------
Good news, it appears that Fenzo supports generic scalar resources as of 0.10.0

See {{com.netflix.fenzo.TaskRequest}} and
{{com.netflix.fenzo.VirtualMachineLease}}.
It should be possible to extend
{{org.apache.flink.mesos.runtime.clusterframework.LaunchableMesosWorker}} to
convey a GPU requirement as a generic scalar resource. We just need to update
the Fenzo dependency to a newer version. I'm not aware of any impediment to
using the latest version, but be sure to add me to the PR review.
> Allow to specify # GPUs for TaskManager in Mesos

> Project: Flink
> Issue Type: Improvement
> Components: Cluster Management, Mesos
> Reporter: Dongwon Kim
> Assignee: Dongwon Kim
> Priority: Minor
>
> 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.
