Ji Yan commented on SPARK-19320:
--------------------------------
i'm proposing to add a configuration parameter to guarantee a hard limit
(spark.mesos.gpus) on gpu numbers. To avoid conflict, it will override
spark.mesos.gpus.max whenever spark.mesos.gpus is greater than 0.
> Allow guaranteed amount of GPU to be used when launching jobs

> Key: SPARK-19320
> URL: https://issues.apache.org/jira/browse/SPARK-19320
> Project: Spark
> Issue Type: Improvement
> Components: Mesos
> Reporter: Timothy Chen
>
> Currently the only configuration for using GPUs with Mesos is setting the
> maximum amount of GPUs a job will take from an offer, but doesn't guarantee
> exactly how much.
> We should have a configuration that sets this.
