Yes they are the same.

[root at rocks7 ~]# cp /etc/slurm/slurm.conf rocks7
[root at rocks7 ~]# scp compute-0-0:/etc/slurm/slurm.conf compute-0-0
  100% 2465     3.6MB/s   00:00
[root at rocks7 ~]# scp compute-0-1:/etc/slurm/slurm.conf compute-0-1
  100% 2465     4.7MB/s   00:00
[root at rocks7 ~]# md5sum rocks7 compute-0-*
41df7afb1ed37cc24d8151dc8d7e6c1e  rocks7
41df7afb1ed37cc24d8151dc8d7e6c1e  compute-0-0
41df7afb1ed37cc24d8151dc8d7e6c1e  compute-0-1

The cpu limit on ruby partition is 20 cores. The nodes in that
partition are Intel Xeons with the following specs

[root at rocks7 ~]# rocks run host compute-0-5 "lscpu"
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit
Byte Order:            Little Endian
CPU(s):                56
On-line CPU(s) list:   0-55
Thread(s) per core:    2
Core(s) per socket:    14
Socket(s):             2
NUMA node(s):          2

There are 14 physical cores on each cpu and therefore 28 physical
cores which means 56 threads. The requested cores are less that 28 so,
it should be ok. I don't know why slurm said that error.
