This fixes the issue where Slurm wrongly considers c4a to have smt enabled (threads_per_core=2). In truth, smt is not applicable for Arm machines. Test with the change: ```sh # As indicated from lscpu, c4a always has 1 thread per core linsword_google_com@c4atest-c4ahighmemnode-0:~$ lscpu | grep "per " Thread(s) per core: 1 Core(s) per socket: 72 # Verify the number looks correct with the change linsword_google_com@c4atest-login-001:~$ scontrol show nodes | grep 72 | head -n2 NodeName=c4atest-c4ahighmemnode-0 Arch=aarch64 CoresPerSocket=72 CPUAlloc=0 CPUEfctv=72 CPUTot=72 CPULoad=0.06 ```
