See the Node's Weight parameter in man slurm.conf.
That can probably be used for what you want.
Weight The priority of the node for scheduling purposes. All things
being equal, jobs will be
allocated the nodes with the lowest weight which satisfies
their requirements. For
example, a heterogeneous collection of nodes might be placed into
a single partition for
greater system utilization, responsiveness and capability. It
would be preferable to
allocate smaller memory nodes rather than larger memory nodes
if either will satisfy a
job's requirements. The units of weight are arbitrary, but
larger weights should be
assigned to nodes with more processors, memory, disk space,
higher processor speed, etc.
Note that if a job allocation request can not be satisfied using
the nodes with the low‐
est weight, the set of nodes with the next lowest weight is
added to the set of nodes
under consideration for use (repeat as needed for higher weight
values). If you abso‐
lutely want to minimize the number of higher weight nodes
allocated to a job (at a cost
of higher scheduling overhead), give each node a distinct Weight
value and they will be
added to the pool of nodes being considered for scheduling
individually. The default
value is 1.

Subject: [slurm-dev] node ordering?
is it possible to specify an order to job distribution to nodes that
are in more than one partition? for instance, i have 10 nodes and the
default partition is 1 through 10 but i want to add a new partition
that is 5 through 10 but i want the have jobs sent to the nodes in
reverse order, 10 through 5. i can get close with the ordering of
NodeName entries but not quite what i want.
