Hi Jim,

I think it may depend on how the "SelectType=“ is setup in your config.
If it’s set as cons_res, then you should be able to do something like
below:

Sum up the number of total cores from the list of nodes before hand, maybe
this isn’t possible though.  Then do:

srun -n<sum_of_cores> -w node[1-50]

Or

srun -n<sum_of_cores> -w /path/to/node_list_file

Hope that helps.

Best,
Chris
