[slurm-users] How to implement job arrays with distribution=cyclic

[Roger Moye]

I have a user who wants to control how job arrays are allocated to nodes.   He wants to mimic a cyclic distribution, basically round-robin assignment of each job within the array.   That is, array element 1 as assigned to node 1, element 2 to node 2, and so on until there is an element running on each node.   Then the next element goes on node 1 and the whole thing repeats until all of the array elements are running or the nodes are full.

So it looks like -distribution=cyclic is what we need but we need this applied to the node assignments for a job array.

Is there a way to accomplish this?   Without this, node 1 fills up first before any cores on node 2 are assigned.

Thanks in advance!
-Roger
