We'll need to add GPU at some point to `ResourceProfile`. @eastcirclek
did you investigate that possibility?
> Allow to specify # GPUs for TaskManager in Mesos

> Key: FLINK-8431
> URL: https://issues.apache.org/jira/browse/FLINK-8431
> 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.
