Yes they are the same. [root@rocks7 ~]# cp /etc/slurm/slurm.conf rocks7 [root@rocks7 ~]# scp compute-0-0:/etc/slurm/slurm.conf compute-0-0 slurm.conf 100% 2465 3.6MB/s 00:00 [root@rocks7 ~]# scp compute-0-1:/etc/slurm/slurm.conf compute-0-1 slurm.conf 100% 2465 4.7MB/s 00:00 [root@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@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.
