   @jomach Sorry, I don't have time to work on this anymore. I don't think Mesos allows you to specify a gpu per Spark app. GPUs are exposed as a scalar resource (like CPUs), so the app just requests a number of gpus. (See http://mesos.apache.org/documentation/latest/gpu-support/) When starting the Mesos agents, you can specify which GPUs to expose as resources but that's only on cluster startup, not per app.
