I am testing our slurm to replace our torque/moab setup here.
The issue I have is to try and put all our node names in the NodeName
and PartitionName entries.
In our cluster, we name our nodes compute-<rack>-<row>
That seems to be problem enough with the abilities to use ranges in
slurm, but it is compounded with the fact that the folks put the nodes
in keeping 1u of space in between.
So I have compute-1-[1,3,5,7,9,11...41]
Why not simply use a comma separated list _generated_ from your
inventory / DNS / /etc/hosts / etc. .?
When you have outliers (2U, 4U -- do they have more resources too!?) it
would make sense to group/partition by resources anyway.
What are you using to manage inventory? Most configuration management
and provisioning tools I know provide you with the necessary tools --
have a look at puppetlabs facter (or alternatives).

Multiple node names may be comma separated (e.g. "alpha,beta,gamma")
and/or a simple node range expression may optionally be used to specify
numeric ranges of nodes to avoid building a configuration file with
large numbers of entries. The node range expression can contain one pair
of square brackets with a sequence of comma separated numbers and/or
ranges of numbers separated by a "-" (e.g. "linux[0-64,128]", or
"lx[15,18,32-33]"). Note that the numeric ranges can include one or more
leading zeros to indicate the numeric portion has a fixed number of
digits (e.g. "linux[0000-1023]"). Up to two numeric ranges can be
included in the expression (e.g. "rack[0-63]_blade[0-41]"). If one or
more numeric expressions are included, one of them must be at the end of
the name (e.g. "unit[0-31]rack" is invalid), but arbitrary names can
always be used in a comma separated list.

Complicating that logic wouldn't make much sense to me.
Mapping host names to partitions shouldn't be too hard to script.
In the worst case you copy the full/per-rack/per-resources host list to
partitions and manually cherry-pick afterwards.
