Thanks for the clarification – I’ll try to dig into this and use execute.cpp as a starting point for my problem… Kind Regards, Hubert

For your case, you may want to split your 50 tasks to small task groups. Also the `execute` cli is just an example framework and it can only launch one task group for now, you may want to enhance it if you want to launch multiple task groups.

I’ve seen some recent changes (MESOS-6096<https://issues.apache.org/jira/browse/MESOS-6096>) in the mesos-execute cli supporting grouped tasks which spawns the task-group on an arbitrary or specified agent node. Tested this yesterday and it works great. But if the task group holds a lot of one-off tasks (let’s say 50 tasks each 4 cores,…) how could one achieve that tasks are evenly distributed over several agents, depending on free resources? Don’t know if this is referred to pods, but do you think mesos-execute will support this? Currently I’m using chronos & cook for batch scheduling, but I’d like to achieve that every batch/group of tasks runs in its own temporary framework like it does with mesos-execute Thanks in advance & kind regards, Hubert —————————————————————————— Deutsches Zentrum für Luft- und Raumfahrt e.V.

We finally have some time to focus and shepherd this work. The epic tracking this work is : https://issues.apache.org/jira/browse/MESOS-2449 Design doc: https://issues.apache.org/jira/browse/MESOS-2449 Your feedback on the design will be most welcome. Once we get agreement on the design, we can start breaking down the epic into tickets. Thanks, Vinod & Jie
