Angel Conde commented on SPARK-24725:
--------------------------------------
Mesos has already the possibility via MPI framework
([https://github.com/apache/mesos/tree/master/mpi]). However that
implementation is 5 year old (and seems to be a proof of concept) and I do not
know whether that approach could be used using Docker images as executors.

> Discuss necessary info and access in barrier mode + Mesos
> ---------------------------------------------------------
>
> Key: SPARK-24725
> URL: https://issues.apache.org/jira/browse/SPARK-24725
> Project: Spark
> Issue Type: Story
> Components: ML, Spark Core
> Affects Versions: 3.0.0
> Reporter: Xiangrui Meng
> Priority: Major
>
> In barrier mode, to run hybrid distributed DL training jobs, we need to
> provide users sufficient info and access so they can set up a hybrid
> distributed training job, e.g., using MPI.
> This ticket limits the scope of discussion to Spark + Mesos. I'm not aware of
> MPI support in Mesos. So we should find someone with good knowledge to lead
> the discussion here.
