hpc desktop launch with node count 2 uses 2 cores on different nodes

Created by: jprorama

It seems that specifying "2" as the number of nodes for an hpc desktop launches a job that has two cores spanning two nodes. From the terminal in such an hpc desktop:

[jpr@c0001 ~]$ srun hostname
c0001
c0002

It would make more sense to use 1 node with two cores for a desktop env. Need to understand how these job parameters are defined/controlled in the underlying resource request. Do we need to distinguish between resource reservation systems?
