Yes, i basically plan to use ClearML as user-friendly cluster manager

and it is 🙂
I think the main "drawback" is that you cannot "reserve" nodes for the multi-node training. The easiest solution is to have high-priority queue that is never used, and then have the DDP master process push into the high priority queue, which will ensure these are the next Tasks to be executed (now the only thing that is missing is preemption to running Tasks, but this automation policy is unfortunately not part of the open-source)
wdyt?
